JAMB Physics 1997 Question 21

Question 21

Quantity of Heat

Equal masses of copper and rubber are raised to the same temperature. After sometime, the copper was observed to be at a lower temperature because

  1. A.the specific heat capacity of copper is lower than that of rubber
  2. B.copper expands more than rubber
  3. C.the specific heat capacity of rubber is lower than that of copper
  4. D.rubber expands more than copper
Show the answer and explanation

Answer: A (the specific heat capacity of copper is lower than that of rubber)

Explanation

Copper has a lower specific heat capacity, so losing the same amount of heat makes its temperature fall more than rubber's.
