An ideal gas at 0 °C is contained within a rigid vessel. The temperature of the gas is increased by 1 C°. What is P_f/P_i, the ratio of the final to initial pressure?

According to Charles' law, at constant pressure, the volume of an ideal gas is directly proportional to its temperature in kelvins. Since the vessel is rigid, the volume is constant, and therefore, the pressure is directly proportional to the temperature in kelvins. The initial temperature is 273 K, and the final temperature is 274 K. Therefore, the ratio of the final to initial pressure is 274/273. Thus, the correct answer is (B).
