Question

How much mass of ice at 0℃ must melt when ∆Q=948000 J of heat energy is added to it?

Answer 1

The ice melted is nearly 2.8 kg

Explanation:

The quantity of heat required to melt the ice can be found by the relation .

ΔQ = m x L

here L is used for the latent heat of fusion .

Its value is 334 J per gram for ice .

Thus m = $\frac{\Delta Q}{L}$ = $\frac{948000}{334}$  = 2836 gram

or = 2.8 kg approx
