(apex) when a cup of water is dropped, as the cup falls, the water in the cup falls out true or false?

Heat is the total potential energy of a substance that can be transferred. true false

4.25g sample of solid ammonium nitrate dissolves in 60.0g of water in a coffee-cup calorimeter, the temperature drops from 22.0 c to 16.9 c. assume that the specific heat of the solution is the same as that of pure water. calculate delta(h) (in kj/mol nh4no3) for the solution proces.
