Term
1st law of Thermo/Law of Conservation of Energy (for heat)
Definition

ΔU = Q-W

change in internal energy equals energy added minus the work

Term
2nd law of Thermo (2)
Definition

heat flows from hot to cold objects

natural processes tend to move toward a state of greater disorder

Term
Efficiency, e (2nd law)
Definition
e = W/Q (work/heat input)
Term
Carnot Cycle (2nd law)
Definition

no friction and each leg is irreversible

Isothermal expansion, Adiabatic expansion, isothermal compression, adiabatic compression

 

Term
Isothermal
Definition
temp does not change
Term
Adiabatic
Definition
no heat flow in or out of the system
Term
Entropy, s (3)
Definition

ΔS = Q/T = heat/temp

entropy never decreases in an isolated system

measure of disorder

Term
Heat energy and specific heat equation
Definition

ΔQ = mcΔT

water always has the highest specific heat, c
