Q

Define specific heat

A

Amount of energy required to raise the temperature 1g of a substance by 1 degree celsius

17
Q

What would have a high specific heat capacity, a conductor or an insulator?

A

Insulator, because it holds onto more heat

18

24
Q

What is a conductor

A

a object that can be easily transferred as heat

25
Q

What is absolute zero

A

the temperature at which an objects energy is minimal

26
Q

What is an insulator

A

a poor energy conductor (coat) keeps your body heat in

27
Q

What is the first law of thermodynamics?

A

that the total energy used in any process is conserved

28
Q

What is the second law of thermodynamics?

A

A system moves from a high energy state to a low energy state

29
