Nitrogen gas is being withdrawn at a rate of $0\mathrm{.}2$ mol$/$s from a $1\mathrm{.}75$ m$3$ cylinder. Initially, the

pressure of the gas in the cylinder is $18$ bar and its temperature is $300$ K$.$ The cylinder is wellinsulated. What will be the temperature and pressure of the gas in the cylinder after $6$ minutes?

Assume Nitrogen is an ideal gas with a constant specific heat capacity.
