Consider $1$ $\text{kg}$ of an ideal gas at $1$ bar and $300$ $K$ contained in a rigid and perfectly insulated container. The specific heat of the gas at constant volume $c_{v}$ is equal to $750 \:J \cdot kg^{-1}\cdot K^{-1}$. A stirrer performs $225$ $\text{kJ}$ of work on the gas. Assume that the container does not participate in the thermodynamic interaction. The final pressure of the gas will be _____________ bar *(in integer).*
