Energy changes in a system, and the ways energy is stored before and after such changes

Question

  1. A. The energy needed to raise the temperature of one kilogram of a substance by one degree Celsius
  2. B. The total energy stored in a substance
  3. C. The energy required to change the state of a substance
  4. D. The energy lost when a substance cools down

Answer

The energy needed to raise the temperature of one kilogram of a substance by one degree Celsius

Explanation

The correct option is "The energy needed to raise the temperature of one kilogram of a substance by one degree Celsius". The energy needed to raise the temperature of one kilogram of a substance by one degree Celsius is right because it directly matches Energy changes in systems: Apply the equation change in thermal energy = mass x specific heat capacity x temperature change.. The other options are less suitable because they change the required Physics relationship, confuse the relevant energy store or use a distractor that does not answer the question.

Common mistake

Misunderstanding Thermal Energy Changes

Students often confuse the equation for change in thermal energy with the equation for specific heat capacity, forgetting to multiply by temperature change.

To fix this, remember that the equation is change in thermal energy = mass x specific heat capacity x temperature change. Ensure you include all three components in your calculations.
