Question

Which will absorb more heat, 10 g of ice at 0° C or 10 g of water at 0° C?

Answer 1

The latent heat of melting of 1 g ice at 0° C is 334 J.

10 g of ice at 0° C require 334 × 10 = 3340 J energy to melt down to 10 g of water at 0° C.

Thus, this much additional energy 10 g ice can absorb as compared to 10 g water at 0° C.
