Convection Flashcards
1
Q
What happens during convection?
A
During convection, as liquids and gases are heated, their particles gain energy and move around.
3
Q
What happens to hot air during convection?
A
Because hot air is less dense than cool air, it is pushed upwards by the cooler air around it. Hot air rises.
4
Q
Why is heat transferred by convection in liquids and gases?
A
Heat is transferred by convection in liquids and gases because their particles are able to move around, rather than remaining fixed like the particles in solids.
