A gas at 5.00 atm pressure was stored in a tank during the winter at 5.0 °C. During the summer, the temperature in the storage area reached 40.0 °C. What was the pressure in the gas tank then?

Question

Using the ideal gas law, the pressure is directly proportional to the temperature in Kelvin. Convert temperatures to Kelvin (5.0 °C = 278.15 K, 40.0 °C = 313.15 K) and use the formula P1/T1 = P2/T2 to find the new pressure: (5.00 atm / 278.15 K) = (P2 / 313.15 K), solving for P2 gives approximately 5.63 atm.
