1.	If accidently the calorimeter remained open to atmosphere for some time during the experiment, due to which the steady state temperature comes out to be 30^(@)C, then total heat loss to surrounding during the experiment, is (Use the specific heat capacity of the liquid from previous questions).
Answer» `20 kcal` `15 kcal` `10 kcal` `8 kcal` SOLUTION :Heat given by the SPHERE `=(1000)(1//2)(80-30) = 25000 cal` Heat absorbed by the water calomiter SYSTEM `=(900)(1)(30-20)+(200)(1//2)(30-20)` `=10,000 cal` So heat loss to surrounding =`15000 cal`.
