How much heat energy is required to convert 0.1000kg of ice at -10.0 C into water at 50 C?

Answer 1

Add heat required for these three component steps:
(1) raising T of ice by 10 C
(2) melting the ice at 0 C
(3) raising T of water by 50 C

Look up the C value for ice and the heat of fusion. You already know the value for liquid water.
