A rigid, sealed metal canister contains oxygen gas. The initial temperature of the gas is 17∘C17^\circ\text{C}17∘C.
Calculate the initial temperature of the gas in kelvin.
The canister is heated so that the temperature of the oxygen inside increases to 45∘C45^\circ\text{C}45∘C. State and explain what happens to the pressure inside the canister. Use your ideas about gas particles.
