Exam-style question
Try this first
A metal block is heated, and its temperature increases from 20°C to 80°C. What does this data suggest about the thermal energy transfer occurring in the block?.
Model answer
What a good answer should say
- The increase in temperature indicates that thermal energy is being transferred to the metal block, causing its internal energy to rise.
- This suggests that the block is absorbing heat from its surroundings, leading to an increase in molecular motion within the block.
Explanation
Why this works
This answer is strong because it directly relates the observed temperature change to the concept of thermal energy transfer. It shows an understanding of how heat affects the internal energy of a substance, which is crucial for interpreting heating data.
