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: Interpret data from a specific heat capacity investigation, including temperature change and energy supplied.. 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 Temperature Change
Students often confuse the temperature change with the total energy supplied during a specific heat capacity investigation.
Emphasize that temperature change is the difference between the initial and final temperatures, and it is essential to relate this to the energy supplied using the specific heat capacity equation.
