If you wanted to compare the abilities of olive oil and peanut oil to gain or lose thermal energy, which unit would you use?

To compare how readily olive oil and peanut oil gain or lose thermal energy, compare their specific heat capacities. Specific heat capacity is measured in joules per gram per degree Celsius (J/g°C), the energy needed to change one gram of a substance by one degree Celsius. Calories and joules alone measure energy, not energy per mass and temperature change.
