These energy exchanges are not changes in kinetic energy. They are changes in bonding energy between the molecules. "If heat is coming into a substance during a phase change, then this energy is used to break the bonds between the molecules of the substance. The example we will use here is ice melting into water.

a. 5.37 g/kg
b. 10.33 g/kg
c. 3.55 g/kg
d. 4.88 g/kg

The Recommended Dietary Intake I'd protein falls withing the range of 0.8 grams per kg to 1.8 grams per kg
For Reuben
