when a solid box is rubbed and due to friction the heat produced is transferred to the system then is the change in temp of the gas inside the box due to work done or Q?????? q1) a thermally insulated closed copper vessel contins water. when the vessel is shaken vigrously the temp rises. amt of heat transferred to the system if we use dQ=mcdT we are definitely gonna get sum value but the question states that the vessel is thermally insulated. is there sth wrong with the formula?????
