1
Q
What is convection?
A
When more energetic particles move from the hotter region to the cooler region and take heat energy with them
2
Q
What is conduction?
A
The process where vibrating particles pass on their extra kinetic energy to neighbouring particles

A
Heat transfer is faster between a body and its surroundings
