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,
