Nitrogen gas in an expandable container is cooled from, Ask an Expert

Academics

Nitrogen gas in an expandable container is cooled from 50.0°C to 10.0°C with the pressure held constant at 3.00 x 10⁵ Pa. The total heat liberated by the gas is 2.50 x 10⁴ J. Assume that the gas may be treated as ideal. For N2 , CV = 20.76 J/mol K.

(a) Find the number of moles of gas

(b) Find the change in internal energy of the gas and the work done by the gas.
