Hi,
What is the difference between Molar Heat Capacity and Specific Heat Capacity? Thank you.

Specific heat capacity measures the amount of heat energy required to raise the temperature of one unit mass, usually one gram, of a substance by one degree Celsius (or one Kelvin). The formula for specific heat capacity is: q=mcΔT (c is the specific heat capacity)
Molar heat capacity measures the amount of heat energy required to raise the temperature of one mole of a substance by one degree Celsius (or one Kelvin). The formula for molar heat capacity is: q=nCmΔT (Cm is the molar heat capacity)

Hello! The difference lies in the quantity of substance being considered: specific heat capacity refers to the heat capacity per unit mass, while molar heat capacity refers to the heat capacity per mole of substance.
