Heat Capacity (C)
A measure of the energy change needed to change the temperature of a substance:
C = q/dT
T or F: Constant Pressure heat capacities are greater than constant volume heat capacities
True
Two Heat Capacities for any substance:
Constant Volume Heat Capacity: C(v) = q/dT [constant volume]

Constant Pressure Heat Capacity:
C(p) = q/dT [constant pressure]
General Heat Capacity Eqn.
q = C*dT
Specific Heat Capacity Eqn.
q = m*c*dT
Specific Heat of Water
1 cal*g^-1*C^-1

C in Celcius
Coffee Cup Calorimeter
-An example of a const. P/V calorimeter
-Measures heat of reaction

q = dH at const pressure
q = m*c*dT
Bomb Calorimeter
-Measures internal energy change at constant volume

q = dU
q = C*dT

Chemistry (Lecture 5)
Four colligative properties of solutions:
1) vapor pressure
2) boiling point
3) freezing point
4) osmotic pressure

depend upon number, not kind
When does a substance boil?
When its vapor pressure equals the local atmospheric pressure
