Answer:

Heat required to melt 42 g if ice is 13,860 J

Step-by-step explanation:

The amount of heat required to melt grams of water at 0°C is given as follows;

The mass of the ice (water), m = 42 g

The latent heat of fusion of ice Δ
H_f= 330 J/g

Therefore, heat required to melt 42 grams is given as follows;

Heat required to melt ice = Mass of the ice, m × The specific latent heat of fusion of the ice, Δ
H_f

Heat required to melt 42 g if ice = m × Δ
H_f = 42 g × 330 J/g = 13,860 J

Heat required to melt 42 g if ice = 13,860 J.
