Im doing a worksheet and the book is all confusing lol.
Im going to take an educated guess on them first.
The amount of heat released when one mole of vapor condenses is called its _____. (that I have no idea lol)
These are either: Always, Never, or Sometimes:
1. Melting and vaporization are exothermic processes. (I think Never true)
2. In order to convert 1 mole of H20(L) to 1 mol of H2O(g), 40.7 kj must be supplied. ( Always true?)
3. When ice metls the temperatures of the ice increases until the entire sample becomes liquid. (Sometimes true?)
4.When ammonium nitrate dissovles in water, the solution gets cold. This is an example of an exothermic reaction. (Always true?) Yeah yeah these are newsbish easy questions I should know, but the book is confusing,(and the class is really boring)
Jschen you should be our teacher and do experiments with food inside the bomb calorimeter=D
