Energy change and change of state, Chemistry

Assignment Help:

On a hot summer day in July, Jennifer is trying to make Popsicles.  If she is using 20.6 g of fruit juice how much heat is released when the Popsicle changes from liquid to solid at 0oC?  Assume the fruit juice in the Popsicle is made entirely of water.  The heat of fusion of water is 2260 J/g

As we know,

311_example of Energy Change and Change of State.png

 
Rounding this to 3 significant digits, the Popsicles will release 46600 J of energy.  

Constant temperature during a phase change.
