Question

4000 calories of heat energy is supplied to crushed ice at 0°C, such that it completely melts to form water at 0°C. If sp. latent heat of fusion of ice is 80 cal g⁻¹, what is the mass of ice?

Answer 1

Given: Q = 4000 calories; L = 80 cal g⁻¹

Heat absorbed by ice (Q) = mL

m = `Q/L`

= `4000/80`

= 50 g
