1
Q

A
Radiation
Conduction
Convection
2
Q
What does conduction transfer?
A
Solids
3
Q
What does convection transfer?
A
Liquids and gases
4
Q
What is conduction?
A
The process where vibrating particles pass on their extra kinetic energy to neighbouring particles
5
Q
Why are metals good conductors?
A
They have free electrons so can move faster and can move freely this is why heat travels fast though metals
6
Q
What is convection?
A
When more energetic particles move from a hotter region to the cooler region and take their heat energy with them
7
Q
What happens when a gas cools?
A
The particles slow down and lose kinetic energy
8
Q
What is condensation?
A
When a gas turns to liquid
9
Q
What is evaporation?
A
When a liquid turns to gas
