Answer:
The average kinetic energy of the oxygen molecules in the container increases
Explanation:
I searched up, "what happens when the temperature of oxygen gas is increased''
As the temperature increases, the average kinetic energy increases as does the velocity of the gas particles hitting the walls of the container. The force exerted by the particles per unit of area on the container is the pressure, so as the temperature increases the pressure must also increase.
this is the answer google gave me so im not sure of you should 100% trust it but its better than nothing
