A rigid container holds $3 \,\text{kg}$ of air. The air is stirred so that its pressure changes from $500 \,\text{kPa}$ to $2000 \,\text{kPa}$, while its temperature is held at $50^\circ\text C$ . The heat transferred is $200 \,\text{kJ}$. Assume the air to behave like an ideal gas with $c_v = 0.714\,\frac{\text{kJ}}{\text{kg}\cdot\text{K}}$. Find the final temperature, the change in internal energy, and the work done.
I am generally confused by what is happening in this question. I imagine we are going from one state to another where the temperature is held constant, and heat is transferred as the pressure rises. Why is it asking for final temperature? Am I miss understanding what is going on?
