Keeping warm Flashcards
1
Q
Heat transfer
A
Conduction
Convection
Radiation
2
Q
Conduction properties
A
Solid
Vibrations
Collisions
An insulator - can’t conduct heat
The vibrations and heat presses from particle to particle
3
Q
Convection properties
A
Liquid
Has
Currents
The particles rise and fall
When convection current are heated, the heat rises to the top
4
Q
Radiation properties
A
Solid, liquid and gas
Vacuum
Infrared EM waves
The hot object gives off waves of heat
5
Q
Heat in homes
A
Thick walls makes conduction slower and the insulation has low thermal conductivity so also it will not allow much heat out - keeps the building warm
