Q

specific heat. What is it?

A

How fast it accepts or releases heat (low c means faster the change) (high c means takes a while to heat)

Q

sauce and cheese on pizza

A

sauce has a HIGHER specific heat, it holds heat longer (if the specific heat is too high, such as wooden spoon, never reaches temperature to absorb energy)

change in enthalpy

21
Q

Energy is represented by the letter….

A

U

22
Q

delta h= delta u + delta pv

A
23

A
25
Q

Reverse Heat Engine (Fridge) (See Slide)

A
26

A

change in free energy

27
Q

Path indepedent?

A

PpTVHUGS

Pressure, density, temp, vol, heat, energy, gibbs free, entropy

28
Q

isobaric

A

no pressure chamge

29
Q

isochoric

A

isovolumetirc

30
Q
A
31
Q

high specific heat

A

hold heats longer

32
Q

Latent Heat

A

deals with phase change (heat absorbed that does not change temperature)

q=mL

33
Q

Boiling point is when

A

atm pressure is equal to vapor pressure (thus at lower pressures, things boil faster)
