Equation differences

[Maya F 1E]

When do you use q=mcpΔT vs. just q=cpΔT?

[Maleeha Amir 2E]

It depends on what the question is asking for and if you are given the mass and if the specific heat includes grams in its units.

[Valeria Perez 3J]

The C value you use depends on the information given in the problem. Cp is the specific heat at a constant temperature, Cv is the specific heat at a constant volume, and Csp, aka C, is the specific heat capacity at a constant specific pressure, but specific to a mass or molar quantity rather than just relating energy to temperature.

q=mcpΔT: when calculating the heat transfer for a given quantity of a substance undergoing a temperature change
q=cpΔT : when figuring out a substance's heat transfer without knowing its mass
