Statement-1: Temperature of a system can be increased without supplying heat.
Statement-2: If the initial volume of system is equal to final volume in a process then work done is necessarily zero.
Statement-3: If an adiabatic curve for a gas intersect with an isothermal curve for the same gas then at the point of intersection, the ratio of slope of the adiabatic and the isothermal curve is `gamma`.
