Question
- A. Joules per kilogram per degree Celsius
- B. Kilograms per meter
- C. Joules per meter
- D. Degrees Celsius per kilogram
Answer
Joules per kilogram per degree Celsius
Explanation
Specific heat capacity is measured in joules per kilogram per degree Celsius, which indicates the amount of energy required to change the temperature of one kilogram of a substance.
Common mistake
Misunderstanding Specific Heat Capacity
Students often confuse specific heat capacity with total thermal energy, thinking it represents the total energy needed to heat a substance rather than the energy required to raise the temperature of one kilogram by one degree Celsius.
Clarify that specific heat capacity is a property of a material that indicates how much energy is needed to change the temperature of one kilogram of that material by one degree Celsius, and emphasize the distinction between specific heat capacity and total thermal energy.
