A copper block of mass 5.0 kg is heated to a temperature of 500 ∘^\circ 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 ∘^\circ C −- 1 and latent heat of fusion of water : 335 J g −- 1]

Multiple Choice Options

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

Step-by-Step Verified Solution

mL=ΔQ=msΔTmL = \Delta Q = ms\Delta T

⇒m=5×0.39×103×500335\Rightarrow m = {{5 \times 0.39 \times {{10}^3} \times 500} \over {335}}

=2.9= 2.9 kg
