8.94 kJ of energy is available to melt 20 g of ice (initially at 0*C) and subsequently to warm the water. What is the water's final temperature in degrees Celsius?
8940 J = 2137 calories
Melting 20 g of ice will require 1600 calories. That leaves you with 537 cal to heat the liquid water. That is enough to heat 20 g up to 27 C.
