The gas pressure inside a container decreases when which of the following happens? the number of molecules is increased and the temperature is increased the number of gas molecules is decreased the temperature is increased the number of gas molecules is increased

they both have a y in them

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
