Wow! I never knew this fact that fire is actually a PROCESS! Thank you sir for the NOW WE KNOW series' new episode!

The familiar teardrop shape of the flame is an effect caused by gravity. Hot air rises and draws fresh cool air behind it. This is called buoyancy and is what makes the flame shoot up and flicker.

Very informative and some thing new we have learnt today. Excellent job done!🙏🌺💐🌟

Because the flame always burn opposite to the gravity and as cool air comes,It becomes hot and rose up and this cycle continues results in creating tear drop shape

Candle flame has a teardrop shape because of gravity. The pull of gravity keeps colder air down replacing the hot air which rises

Really great presentation 👍🏻 It has tear drop shape because density of gases is most on the down side and least on the top most side

When air is heated, it moves upward and the gravity pulls colder, denser air down to the base of the flame. Thus a continuous cycle of upward moving air or the convection current gets created which gives the flame its teardrop-like shape.

When that cooler air is heated, it too rises up and is replaced by cooler air at the base of the flame.

the heat from the flame heats up the air also which goes up due to its lighter weight and the cooler air comes down and becomes hot again when comes near the flame and goes up again. This leads to an upward shape of flame every time.

When the cooler air is heated it too rises up and is replaced by cooler air at base of candle flame. This creates a continuous cycle of upward moving air around the candle flame and that is due to convection current which gives the flame elongated and tear drop shape. Thank you 💖

Due to heat produced by fire, the air around it gets heated and rises upwards. By the impact of this motion of air around, fire also rises upwards.

The Teardrop shape of the flame is an effect caused by gravity. Hot air rises and draws fresh cool air behind it. This is called buoyancy and is what makes the flame shoot up and flicker.

As the cool air around the flame gets heated it rises up. Due to continuous upward flow of air it puts pressure on the flame and thus the flame takes the shape of a tear drop

The familiar teardrop shape of the flame is an effect caused by gravity. Hot air rises and draws fresh cool air behind it. This is called buoyancy and is what makes the flame shoot up and flicker. And this is why the flame is having a teardrop shape

Flames have this fancy tear drop shape due to effect caused by gravity in which hot air rises and draws fresh cool air behind it .

The flame looks like this because when it burns it heats the nearby air making them lighter and go upward . To fill the space colderair comes in and they also get warm and go upward. In this process flow of air make the flame going upward

The teardrop shape of the flame is mainly because of the transverse air movement around the flame.

The teardrop shape of the flame is due to gravity. Hot air rises while the fresh cool air draws behind it. But, if you light a match in zero gravity, the flame spreads outwards like a balloon. So, we can conclude that the shape of flame due to gravity.

Flame has an unique shape of tear drop, as a result of the gases that are escaping gravity while emitting the light as they are excited

Because of hot air, cold air and gravitation.

🔥 🔥 🔥

It raises against the gravity and it is low weight

😍🤩

Thats what i thought during sleep

Answer => because of the temperature of the flame the surroundings gases heat up and hotter gases are lighter as compared to gases at normal temperature so they rise up That's why a flame always points up and has a tear drop shape !

I think that fire acts as a binding substance of water,air and earth in everything

Because of the air near the flame is hot and far from the flame is cold due to this hot air is less denser than cold air and less denser hot air goes up and it is continue 🔥

Due to atmosphere and convection of gases

The reason behind the tear shape of the flame is because fire uses oxygen to get heated and when it gets heated up it moves upwards the cool air takes the place of the hot air which went upwards. Thank you for the great vdo byjus.😊😊

Flames always point upwards because of gravity that they go upwards. Hot air rises upwards, and as cool air comes being heavier it settles down but it again heated upwards. This is a continuous cycle

@byjusclasses

Sweet, short and correct. Keep it up!!

When the combustion begins, the cooler air around the flame rises up. This causes the flame to be pushed up along with the air. Therefore, the flame has a teardrop shape.

Hot air go goes up and cold air comes down and then the cold air heated and goes up this forms a cycle upward so...

Lets play science 🔥🔥😍😍

It's simple why flame 🔥 has a fancy tear drop shape.... It's why because, when the fire is burning( in a candle) , the bottom of the flame would be using up the air molecules present at its bottomfor its combustion. Now the air molecules present at the bottom as well as around it gets heated due to which it gets lighter in mass again due to which it moves upwards. The denser air at the bottom provides a hemispherical wide bottom. And the lighter air on moving upwards , widens in volume and spread around the surrounding, due to which the flame becames narrower and narrower. This it how the 🔥flame got its unique fancy tear drop shape......

Absolutely right and simple explanation!

The pull of gravity draws colder, denser air down to the base of the flame, displacing the hot air, which rises. This convection process feeds fresh oxygen to the fire, which burns until it runs out of fuel. The upward flow of air is what gives a flame its teardrop shape and causes it to flicker.

Absolutely right!

earth's pull is what makes hot air rise. And this convection shapes flames into their familiar form because of gravity

The reason behind the tear shape of the flame is as the temperature of the air around the flame becomes warm and warm air goes up due to lower density than colder air above. So, the flame also goes with it thus giving a tear shape. By the way, in space, as there is no air and no gravity thus no use of density that's why flames in space are spherical. #ProudBYJUite 💜💜💜

Thank you 1st comment

Thank you BYJU'S 💜

Thanks a lot sir for Explaining this question that I had for a few Weeks, Btw All the flames on Earth Has the Tear Drop shape because a Flame always burns in the opposite of Gravity so on Earth, Gravity is pulling downwards so the flame will go Upwards thus creating a Year Drop Formation, but in Space As there is no Gravity a flame will be of a Semi-Circular Shape

You are right just a slight addition....Due to continuous flow of hot and cold air a convection current cycle sets up....obviously this happens due to gravity and it provides tear drop shape to flames....In space there is no air as well as gravity so burning gases will radiate out in various directions providing circular appearance to flames.

Flame has a tear shape due to hot gases under the flame that rises upward due to lower density and give it it's shape as a tardrop

Air near fire heats up and raising and vaccum space occupied by cool air and again heats and raising upward and the process continues, hence it looks like tear drop.

for gravity

It is in that peculiar shape because hot air rises quickly in the air. It cools down as it rises so the flame is thinner at the top. Go put your hand above the fire to feel the hot air rising.

due to gravity

So flames that burn hot enough will have electrons ripped from their respective atoms making them ions and thus being plasma. So putting a candle in an electric field would be a way to test if there are ions in the flame. Veritasium did this and demonstrated the flames, even low temperature flames from the candle, will be attracted to the positive and negative electrodes and thus flames are made of ions and are a plasma.

Due to Surface tension

because of convenction

sir the flames are like this because of the air that helps it grow upwards and it gives a fancy shape as you told i think so

@byjusclasses

What you are thinking is quite right!

Because of the gravity

When a candle burns, the flame heats the nearby air and starts to rise. As this warm air moves up, cooler air and oxygen rush in at the bottom of the flame to replace it. When that cooler air is heated, it too rises up and is replaced by cooler air at the base of the flame. This creates a continual cycle of upward moving air around the flame (a convection current), which gives the flame its elongated or teardrop shape.

Well sir, I think the flame has shape of a tear drop because of the fact that hot air moves up..

its easy peasy just because of gravity and atmospheric pressure

The flame is in teardrop shape because of gravity and a process called convection

The flame looks like tear shaped because of gravitational force 👍

Gravity

It gets a tear drop shape because of air movement

Bcoz all gases around the flame exhausted so flame take a straight shape-😄

can you please explain what is the difference between light and fire, and can light exist without the spark of fire

The shape of the Flame is due to the gravity present on the Earth we know the hot air rises and the cool one comes down and the complete effect of these two given the Flame it's peculiar shape but if we light up flame in zero gravity it will move outward like balloons

This guy is awesome

For the surface tension may be the flame's shape look alike water droplet.

That shape of flame is due to gravity on earth.

So does it mean that a combustion flame is an impure plasma, as in a plasma with some gas impurities with lesser heat, or was it just in the in-between state because there's not enough energy to turn it into plasma??? 🤔🤔🤔
