Here to cram the night before paper 1 in 2019

but do we not need to know about the other ways to cool buildings e.g using aluminium foil behind radiators??

Hi sir, i have a CGP Physics 9-1 AQA complete revision and practice book and it said that there was Conductors and Convections. I havent seen you post a video based on those topics. Is there a chance that they have been removed for the exam???

Do we need to know about convection?

best teacher

cheers shaun

have you missed video about infrared radiation because thats triple for p2?

whatever would i do without you!

can someone explain the colour spectrum thing? i understand white light is the hottest, but some videos tell me that the blue-purple is hotter than the red (like this vid) while others make it seem as though blue/purple is the coolest? does it differ depending on the scenario or? im confused.

Can you do p1 to p4 revision please

Saving my physics mock todat

for convection why do less dense fluids rise? is it density? if so why? and why doesn't the hot dense particles share their kinetic energy through colliding thus resulting in a cold particle again? is kinetic/thermal energy interchangeable?

@Freesciencelessons

3 жыл бұрын

Hi. Thermal energy and kinetic energy are effectively the same on a molecular level. Particles with a greater level of thermal energy will transfer this to particles with a lower level. Less dense fluids rise because in order to sink, an object must displace its own mass of the surrounding fluid. As a region of fluid become less dense than the surrounding fluid, it's not possible for it to displace its own mass, so it rises.

So good

Thanks

I cant find this on the aqa spec or maybe im just not understanding the wording, but is the part about modern houses there?

It's on page 20. "Students should be able to describe how the rate of cooling of a building is affected by the thickness and thermal conductivity of its walls."

I was just wondering how the cavity increases the rate of thermal energy out of the house. Isn't air an insulator?

@amelia-ru4pt

i think its the conductivity of the materials more than the cavity, i.e. bricks conduct heat so insulation is necessary

Air is an insulator, but I believe that the foam, or whatever material they use, in the cavity is a better insulator than air

Yes they're relevant for every year until the spec changes. That might not be for another 4-5 years. If the spec changes, then I'll remake the videos.
