A rigid container of fixed volume \(V_0\) holds an ideal gas initially at absolute temperature \(T_0\) and containing \(n_0\) moles. The container is heated uniformly such that its absolute temperature \(T\) increases at a constant rate over time. Simultaneously, gas escapes through a small puncture at a constant molar rate over time. Which of the following best describes the shape of the graph of gas pressure \(P\) as a function of absolute temperature \(T\) for the gas remaining in the container?
