100 g of ice at C melts completely to water at C by absorbing heat. Taking J/g and ignoring the small change in volume, find the increase in internal energy in kJ (one decimal).
Answer:
33.40
Solution:
The work done on the surroundings is negligible, so J = kJ. The heat is absorbed, and the internal energy rises.
