1.	When 20.0 g of ammonium nitrate( NH_(4)NO_(3)) is dissolvedin 125g of waterin a coffee-cup calorimeter, the temperature fallsfrom 296.5 K to 286.4K. Findthe value of q for the calorimeter. (Treat heat capacityof water as the heat capacityof the calorimeter and its contents) .
Answer» SOLUTION :As heatcapacity of water `=` heat ( capacityof CALORIMETER , the heat gained by water `=` heatlost bythe calorimeter `125xx ( 296.5 - 286.4) XX 4.18 J= 5282J = 5.282J`
