What is the total number of joules released when a 5.00-gram sample of water changes from liquid to solid at 0°C?

(1) 334 J (3) 2260 J

(2) 1670 J (4) 11 300 J

Energy released from changing the phase of a substance from the liquid phase to solid phase can be calculated by using the specific latent heat of fusion. The heat of fusion of water at 0 degrees Celsius is 334 J/g. Calculation are as follows:

Energy = 5 grams x 334 J/g

Energy = 1670 J
