A rigid, sealed metal cylinder contains a fixed mass of gas initially at room temperature. The cylinder is then heated, causing the temperature of the gas to rise.
Which row correctly describes the change in the average kinetic energy of the gas particles and the pressure of the gas?
Average kinetic energy: increases; Pressure: increases
Average kinetic energy: increases; Pressure: stays the same
Average kinetic energy: decreases; Pressure: decreases
Average kinetic energy: stays the same; Pressure: increases
