Question
What happens to the thermal energy of a substance when it is heated, and how does this relate to its temperature change?
Answer
When a substance is heated, its thermal energy increases, leading to a rise in temperature. The amount of temperature change depends on the mass of the substance and its specific heat capacity.
Explanation
This question assesses understanding of the relationship between thermal energy and temperature change. It requires students to explain how energy transfer affects temperature, linking concepts of energy stores and specific heat capacity.
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.
