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 Jg -1 °C -1 and latent heat of fusion of water: 335 J g -1 ]
Text Solution
Verified by ExpertsThe correct answer is:
C
Heat given by block to get 0°C temperature
Q 1 = 5 x (0.39 x 10 3 ) x (500 - 0)
= 975x10 3 J
Heat absorbed by ice to melt m mass
Q 2 = mx(335x10 3 ) J
Q 1 = 
Q 2
mx(335x10 3 ) = 975xl0 3
m= 
=2.910kg
