Question

using the proper units for energy
which is the metric standard for measuring energy?
which unit is used for specific heat capacity?
if you wanted to compare the abilities of olive oil and peanut oil to gain or lose thermal energy, which unit would you use?

Explanation:

The metric standard for energy is the joule (J). Specific heat capacity is measured in joules per kilogram - degree Celsius (J/(kg·°C)). To compare the abilities of substances like olive oil and peanut oil to gain or lose thermal energy, the specific - heat capacity unit (J/(kg·°C)) is used as it describes the amount of heat energy per unit mass needed to raise the temperature by one degree Celsius.

Answer:

The metric standard for measuring energy: Joule (J)
The unit used for specific heat capacity: J/(kg·°C)
The unit to compare the abilities of olive oil and peanut oil to gain or lose thermal energy: J/(kg·°C)
