Answer:
D) All of the above
Explanation:
When the temperature increases, it means that the kinetic energy of the gas molecules had increased too because the temperature is a way to measure this kinetic energy. When this happens, the velocity of gas molecules increases because kinetic energy and velocity are directed related:
[tex]Ek = \frac{mv^2}{2}[/tex]
Where Ek is the kinetic energy, m is the mass and v is the velocity.
If the velocity increases, there will be more collisions between molecules, so, with more collisions, the pressure, which is the measure of the force a gas makes in the system, will increase. So, all the answers explain why the pressure of a gas increases when the temperature increases.
