What is the formula for defining heat capacity, S, of a substance?

S = Q / T

S = ΔQ * ΔT

S = ΔQ / ΔT (correct)

S = Q * T

What property of a substance determines the change in temperature when a given quantity of heat is absorbed or rejected by it?

Change in temperature property

Nature of substance property

Heat capacity per mole

Specific heat capacity (correct)

What is the SI unit of molar specific heat capacity?

J mol–1 K–1 (correct)

J kg–1 K–1

kg–1 J K–1 mol

K–1 J mol–1
