NEET Physics Heat Transfer MCQ Question
Type: MCQ-numerical-Medium-Class 11
A copper block of mass 2.5 kg is heated in a furnace to a temperature of 500°C and then placed on a large ice block. What is the maximum amount (approx.) of ice that can melt? (Specific heat copper = 0.39 J/g°C heat of fusion of water = 335 J/g).
A
2 kg
B
5 kg
C
5 kg
D
0.5 kg
Correct Answer
Option B
Detailed Explanation
The heat lost by copper is mcΔT. Equating this to the heat gained by ice (mL), we find the mass of ice melted is 1.5 kg.
