A thermally insulaated, closed copper vessel contains water at `15^(0)C`. When the vessel is shaken vigorously for 15 minutes, the tempreture rises to `17^(0)C`. The mass of the vessel is 100 g and that of the water is 200 g. the specific heat capacities of copper and water are `420 Jkg^(-1) K^(-1)` and `4200 J kg^(-1)K^(-1)` respectively. negalect any thermal expansion. (a) how much heat is transferred to the liquid-vessel system ? (b)how much work has been done on this system? (c ) how much is the increase in internal energy if the system ?
