Energy changes in a system, and the ways energy is stored before and after such changes
Question
- A. The energy needed to raise the temperature of one kilogram of a substance by one degree Celsius
- B. The total energy stored in a substance
- C. The energy required to change a substance from solid to liquid
- D. The energy released 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: Explain how energy supplied to a material links to its mass, temperature change and specific heat capacity.. 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
Confusing Specific Heat Capacity
Students often confuse specific heat capacity with thermal energy, thinking they are the same concept.
Remember that specific heat capacity is the energy needed to raise the temperature of one kilogram of a substance by one degree Celsius, while thermal energy refers to the total energy within a system due to its temperature.
