An electrical heater supplies heat to a system at the rate of 100 watt. If the system performs work at the rate of 75 joules per second. At what rate is the internal energy increasing?
In changing the state of the gas adiabatically from equilibrium state to another equilibrium state, amount of work is equal to 22.3J is done on the system. if the gas is taken from state A to state B via a process in which the net heat absorbed by the system is 9.35cal, how much is the net work done by the system in the later case?
