Question

A block of mass 2.5 kg is heated to temperature of
500°C and placed on a large ice block. What is the
maximum amount of ice that can melt (approx.).
Specific heat for the body = 0.1 cal/g°C.
(1) 1 kg (2) 1.5 kg (3) 2 kg (4) 2.5 kg​

Answer 1

Answer:

option 2 is correct

Explanation:

latent heat of ice = 79.7 cal/gm

heat given by block = heat absorbed

by ice (latent heat)

2.5*0.1*500 =mass of ice*79.7

mass of ice = 125/79.7 = 1.56 kg
