difference between Cp and molar heat capacity

Postby Jaden Haskins 2E » Wed Feb 17, 2021 4:09 pm

On the constants and equations sheet, there is molar heat capacity of water (liquid) and Cp listed as two separate values. They are basically the same number with the same units, one is just rounded up, but I wanted to make sure there was no difference between the two. Cp is just the symbol for molar heat capacity right?

Yes the 2 Cp values listed on the equation sheet are the same. Cp (water) is molar heat capacity at a constant pressure. I believe the value given on the equation sheet is the Cp for liquid water.

Cp: In a system, Cp is the amount of heat energy released or absorbed by a unit mass of the substance with the change in temperature at a constant pressure. ... So, Cp represents the molar heat capacity, C when pressure is constant. The change in temperature will always cause a change in the enthalpy of the system.
