Volume measurement by displacement method | Density | Physics
Measuring cylinders help in finding volume of liquids, but what of bodies with irregular shapes? This video shows how to use the water displacement method to measure the volume of bodies. A measuring cylinder or overflow vessel is used to determine two volumes - the volume before a body is immersed and the volume with the body immersed. The reasoning is that the immersed body has displaced its own volume, so by calculating the difference in volume of water, we can find the volume of the body. Once we find the mass of the body, the density can then be calculated as mass/volume. Note that this method only works of the object whose volume is to be measured completely sinks in water.

Amazing video. Truly makes me understand why people call me dense. 👍
the video i was looking for! thank you for making it short and straight to the point!
i love that u went right to the point! great explanation!
This is so helping, now I didn't understand how to measure the density of the floating object.
good teaching , words speaking very clear and high intensty
It is really helpful, i now fully understand it by its nature than just its formula.... Good job😊😊😊
really i like this channel.this helps me in my study.i always thankful for your work.
I have an experiment to do for school and this helped so much!! Thank you! :D

Thank you this really helped i will be using this channel more x
Simply outstanding whole things on just on 2min.
i love this channel very much
This is amazing thank you!!
This helped me study for my test! Thank you so much!
Excellent explanation professor 💐👍
I am now at age 25. I can't understand Density , volume in my whole life Thanku for this video Now I understand what is mass , density & volume
It was very helpful thanks😊May Allah bless you
Thanks. Clearer now.
thank you, sir, it helped a lot
Sir u explained very well
Pretty helpful
Thank you!
Hope it will help me for my practical tomorrow
well done
Thank u sir
It's nice but I didn't understand how to measure the floating stuff

We can sunk it by force and then calculate
To measure a floating object, could you do it like this?: First weigh the very light object on the scale. Say that it weighs 50g. Then you could use fine, almost weightless thread to tether the object to the bottom and pull it under water. The object will displace water. Let's say the level rises to 1600 ml, so amount displaced equals 1600 - 1000 = 600 ml, which is same as 600 cm^3. Now, you'd calculate density at 50g / 600 cm^3 = 0.08 g/cm^3. The answer should be a number less than 1 because water is 1 g/cm^3, and objects that float have a specific gravity less than water, so this seems correct.

there is another way im not sure if it's correct, so basically as you said we weigh the light object let's say its 50g, you could then bring a heavy solid and measure it and see it's volume alone, then you put it above the light object for the light object to sink and you subtract the water and the heavy object which leaves you with the light object. (correct me if im wrong)
if we tether a ball to the bottom of a tank and put the tank on scale and then we cut the thread, shouldn't the scale read higher momentarily until the ball reaches the surface or reaches its terminal velocity?
Thanks
How would you find the volume of sand, air, or cotton?
chem gang
Good
I want to learn for calibration density of water
if we had taken water 700 ml instead of 1000 ml, would the result be same or its independent of water volume?
❤
But this would not work for hollow objects right?
I had a test talking about measuring. Pretty sure I'll fail, but I did my best ;-;...

Can we find if it is float?
Oh yeah yeah
Shout out sa BSEE 1 ndu
I am really sorry but can I ask what do we mean by irregular
Wouldn't the value of gravity count in measuring density?
last min lab report tingz
C/D = 3.17157
Missing margins of error on the displacement and weight process so not sure you can have 3 significant figures in the result.

dont you have to convert milliliters to meter cube

1 milliliter is equal to 1 cubic centimeter So here: 520 g / 220 cm^3 = 2.36 g/cm^3

when he showed us the new water level it was 1220 not 1200 wtf?

it is blocked by the line at which the wat is at, plus they measure it by the meniscus of the water which would have been at 1220ml
