Worked practice questions

Objects X and Y receive equal thermal energy, but X's temperature rises more. This shows that X has:

  1. a lower melting point than Y
  2. a lower mass density than Y
  3. a higher conductivity than Y
  4. a lower thermal capacity than Y
Show answer and solution

Correct answer: D. a lower thermal capacity than Y

1. Thermal capacity is the energy needed to raise an object's temperature by one degree. 2. Both objects receive the same quantity of energy. 3. The one whose temperature rises more must need less energy per degree. 4. So X has the lower thermal capacity. 5. Thermal conductivity governs how fast heat travels through a body, not how much its temperature rises — confusing the two was the recorded error. _Source: NECTA CSEE 2022 Physics 031, Question 1: Multiple Choice, item (vi)_
