Work is done on a adiabatic system due to which its velocity changes from 10 m/s to 20 m/s elevation increase by 20 m and temperature increases by 1K. The mass of the system is 10 kg, Cv = 100 J(kg.K) and gravitational acceleration is 10 m/s2. If there is no change in any other component of the energy of the system, the magnitude of total work (in kJ) on the system is _______
