a calorimeter contains 50g of water at 50*c. the temp falls to 45*c in 10 minutes. when the calorimetr contains 100g of water at 50*c, it takes 18 mins for the temp 2 bcum 45*c. find the water equivalent of the calorimeter. ( ANS:12.5G )
The amount of heat to be desipated will be proportional to mass of water plus water equivalant of calorimeter. If water equivalent is W then (50+W)/(100+W)=10/18 This gives W = 12.5 grams
