Heat Capacity

Flash cards for lecture 4 of thermo

What is heat capacity and what’s its equation.

Heat capacity, Cs, refers to the heat supplied divided by the temperature change. 

What is he unit for heat capacity per unit mass

Heat capacity per unit mass = J K^-1 g^-1

What’s the symbol and units for Molar heat capacity

Molar heat capacity, Cm, has units of J mol^-1 K^-1 

Equation for q using molar heat capacity

q = n Cm ΔT 

What are the two values for Cm when gaseous

For gases, there are two values of Cm 

• Molar heat capacity at constant pressure Cp in J K^-1 mol ^-1 

• Molar heat capacity at constant volume Cv in J K^-1 mol ^-1
