Question

Thermodynamics.

please answer the 2 questionn, i will give a good feedback. thank you, 

show solution step by step.

First Law of Thermodynamics Conservation of Energy - Closed Systems. 1. One-half kilogram of gas is held in a rigid tank. An external motor does 50 kJ/kg of work on the gas by means of an impeller while the stored energy of the gas increases from 120 kJ/kgt0 160 kJ/kg. Determine the heat transfer in kJ/kg. 2. The stored energy of a fluid in a closed system changes from 500 to 440 Btu/lbm while the fluid performs 30,000 ft-lbf /lbm of work. Compute the heat transfer.
