Question 91

8.0 g of water at 30∘C30^\circ\text{C}30∘C is poured onto a large block of ice at 0∘C0^\circ\text{C}0∘C. The water cools to 0∘C0^\circ\text{C}0∘C and some of the ice melts.

Assume that all the thermal energy lost by the water is gained by the ice.

What is the mass of the ice that melts?

The specific heat capacity of water is 4.2 J/(g ∘C)4.2\text{ J/(g }^\circ\text{C)}4.2 J/(g ∘C).

The specific latent heat of fusion of ice is 336 J/g336\text{ J/g}336 J/g.
