heat escaping

gem0688

Hi,

Just a quick question, I just want to check that i am on the right lines!

When heat escapes through the top of a container which does not have a lid, is that due to convection? i/e hot air is less dense than cold air, so rises.

Cheers

Out of conduction, convection and radiation, you are correct that convection would account for the majority of the heat loss. There will be a little due to IR radiation, but that won't account for much unless the interior of the container is red hot.
