Explain how gas volume depends on temperature and pressure.

Question

jfraser · Answer

Imagine you've got a container with some number of gas molecules inside. Gases craete pressure by colliding with the walls of the container. The more collisions, the higher the pressure will be.

What will happen to the molecules when the container is heated?

What will happen to the collisions when the container is squeezed?

could this be explaining it in terms of kinetic theory of matter?

jfraser · Answer

partially, yes

anonymous · Answer

any other explanation then

jessicap · Answer

Decrease pressure=increase volume; Increase pressure=decrease volume
Decrease temperature=decrease volume; Increase temperature=increase volume

In other words, volume is inversely proportional to pressure, and directly proportional to temperature.
