Energy changes in a system, and the ways energy is stored before and after such changes
Question
- A. change in thermal energy = mass x specific heat capacity x temperature change
- B. change in thermal energy = mass + specific heat capacity + temperature change
- C. change in thermal energy = mass / specific heat capacity x temperature change
- D. change in thermal energy = mass x specific heat capacity - temperature change
Answer
change in thermal energy = mass x specific heat capacity x temperature change
Explanation
This equation shows how the change in thermal energy is calculated based on mass, specific heat capacity, and the temperature change.
Common mistake
Confusing Energy Stores
Students often confuse the decrease of one energy store with the increase in another without understanding the relationship between them.
To fix this, clearly link the concepts by explaining how energy is conserved and transferred between stores, ensuring to illustrate specific examples of energy transformations.
