Question

1. Find the energy required to melt 255g of ice at 0°C into water at 0°C

Answer 1

E = 85170 J (/ 85.2 kJ)

Step-by-step explanation:

Take the latent heat of fusion of water be 334J / g.

From the equation E = ml,

E = energy required (unknown),

mass m = 255g,

latent heat of fusion l = 334J / g,

E = 255 x 334

E = 85170 J (/ 85.2 kJ)
