I couldn't be able to learn this at school for one whole year until now, just learn within 3 minutes.

[dvzdeqi]

I have learned ... kinda a lot ngl great vid.Cheers

You missed Loft insulation materials which can deduce the affect of convection. :)

[vuroe]

im using this over my acc revision books bc this gives way more detail and also useful examples

[Rxbyy]

Your videos are amazing, and are so simple to understand! <3

[harry-jipq]

0:53 is that a sam fisher reference? the cat in the window lol

[flikxify]

Can you further explain more ways to stop emenergy loss like loft insulation etc.

[flikxify]

I’ve told all my friends about you thx

Hi Cognito, why the title included Aerodynamics? I haven't understand what part of video talked about that, it is about the air gap?

[Sandra-bbgq]

We can make the house painted white right?

[jacklogan]

i should have been revising earlier man im cooked 💀

[keroy]

no way i did this in class and didnt understand now i know legit everything

[jonesyjr]

My physics exam starts tomorrow so of course I’m here getting some last minute revision

[idrk]

Double glazing contains an air gap- can’t that cause convection?

[themoviehub]

what does convection and conduction mean any1
