An ideal monoatomic gas goes through a cyclic process consisting two isochoric and two isobaric lines. The absolute temperature of the gas rise two times both in isochoric heating and isobaric expansion. If number of moles are three, find efficiency of cyclic process. Heat is supplied to a diatomic gas at constant pressure. The ratio [...]
A Carnot engine having a perfect gas gas the working substance is driven backwards and is used for freezing water already at 0 C. If the engine is driven by 500 W electric motor with an efficiency of 60% how long will it take to freeze 15 kg of water? The working temps of the engine are 15 C and 0 C. The system involves no energy losses. Given latent heat of ice =333×10^(3)J kg^(-1).

Two Carnot engines A and B are operated in series. The first one A receives heat at 900K and rejects it to a reservoir at T K. The second engine B receives the heat rejected by the first engine and rejects it to a heat reservoir at 400K. Calculate the value of T, when the efficiency of two engines is the same.
