P2-Energy Transfers by heating Flashcards
1
Q
why are metals good thermal conductors?
A
They have free electrons to carry energy
2
Q
what is specific heat capacity?
A
the amount of energy required to raise 1kg of material by 1℃
3
Q
specific heat capacity equation
A
Energy=mass(kg)x specific heat capacity(J/Kg℃)x temperature change(℃)
4
Q
Why are metals good thermal conductors and non metals not so good
A
metals are good thermal conductors because they have free electrons to carry energy. non metal solids are usualy poor conductors because they need atomic vibrations to carry energy
