Aimee Johnson · Answer 1

The heat that ice will need to melt at 0 °C is equivalent to the latent heat of fusion of water, which has a value of 334 Joules per gram.

Grams of water = 20 x 1000

H = ml; where H is the heat, m is the mass of water, l is the latent heat of fusion of water.

H = 20000 x 334

= 6.68 x 10⁶ Joules

The answer is C
