Question
What is the equation used to calculate the change in thermal energy when the temperature of a system changes?
Answer
The equation is change in thermal energy = mass x specific heat capacity x temperature change.
Explanation
This question tests the student's understanding of the relationship between thermal energy, mass, specific heat capacity, and temperature change. It requires recall of the specific formula used in calculations related to thermal energy changes.
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.
