Question

A copper block of mass 5.0 kg is heated to a temperature of 500°C and is placed on a large ice block. What is the maximum amount of ice that can melt?

[Specific heat of copper 0.39 J g–1 °C–1 and latent heat of fusion of water : 335 J g–1]

• A. 1.5 kg
• B. 5.8 kg
• C. 2.9 kg
• D. 3.8 kg

Answer 1

Answer: (A)

1.5 kg

Answer 2

The correct option is(C): 2.9 kg.

mL = Δ Q = ms Δ T

$⇒m=\frac{5×0.39×10^3×500}{335}$

= 2.9 kg
