If you increase the temperature of a gas, its particles (atoms or molecules) will speed up. If it is in a closed container, the pressure will also increase.

∙ 12y agoIn order to understand what happens to the temperature of a gas when the volume of the gas increases, you must understand a couple of things first.
For starters, a gas is one of the three states of matter (liquids & solids). Yet, what does being called a "gas" actually mean? The main difference between a substance in gaseous, liquid, or solid state is the arrangement, vibrations, and free movement of the molecules.
I'm sure you think of a gas as free-floating particles, which is sort of right. If we put a gas into a closed container, it will assume the shape and volume of whatever is containing it... because the molecules can freely move past each other. Due to the freedom of movement and space, gases are highly compressible. They also vibrate and move at fast speeds, bouncing and colliding with other molecules and the walls of the container.
Now let's get to your question, the temperature or heat or energy of a gas comes from the amount of collisions of the molecules. If you are increasing the volume, you are providing more space between the molecules. Therefore, it is a greater distance for a molecule to collide into a wall or another molecule. As a result, the less collisions, the less heat given off, and the temperature will drop.
But if you meant increasing the volume by adding more gas to the original container, then you are adding more molecules into a fixed space... which will increase the temperature.
I hope that wasn't too confusing!

If the number of moles of gas decrease what happens to the volume?
According to Avogadro's Law, the number of moles is proportional to the volume. Therefore, if the number of moles of gas decreases, the volume also decreases.
What relationship does Avogadro's law described?
the relationship between volume and moles-APEX
How many moles are in a container with a volume of 12.6 L and a pressure of 115 kPa at a temperature of 28.1 C?
The number of moles is 0,579.
What happens to the volume of a gas when the number of moles doubles (all else held constant)?
When the number of moles of a gas doubles and all else is constant, then the volume also doubles.
How many moles of N2 are in a flask with a volume of 250ml at a pressure of 300.0 kPa and a temperature of 300.0 K?
The number of moles is 0,03.
What happens to pressure on the molecule level when the number of moles of gas is increased at constant volumeWhat happens to the number of collisions with the side of the container?
Pressure in a constant volume (container) is directly proportinal to the number of moles and to the absolute temperature (in K)p :=: n * T with ':=:' meaning 'proportianal to' (not: equal to!)The number of collision is related to and determined by the pressure-value only! (pressure is the result ofcollisions only)
What happens to the volume of gas when you double the number of moles of gas while keeping the temperature the same?
The volume is doubled.
Why does pressure increase with an increase in temperature?
PV=nRT where P=pressure, V=volume, n=no. of moles, R=gas constant, T=temperature(K) since volume and the number of moles remain constant, they can be ignored and we can assume:- that P is proportional to T and thus if temperature is increased, pressure will also increase.
How many moles is 15.2L of CH4?
It depends on temperature,pressure and volume.THese are needed to find number of moles
If the number of moles of gas decrease what happens to the volume?
According to Avogadro's Law, the number of moles is proportional to the volume. Therefore, if the number of moles of gas decreases, the volume also decreases.
What happens to the volume of the gas when the number of moles is doubled?
The ideal Gas Law states the following: pV=nRT p=pressure [pa] V=volume [m³] n=number of moles R=constant T=temperature [K] So, if you multiply the number of moles by 2, and all the other variables are not changed, your volume will also be multiplied by 2.

Does Charles law the temperature and number of moles stay constant?
Charles' Law: V1/T1 = V2/T2 The number of moles and the pressure are constant.
What happens to the altitude and boiling point as the pressure is increased?
As altitude increases, pressure decreases, so boiling point decreases, so the liquid would boil at a lower temperature and would not be able to get as hot and remain a liquid. As pressure is increased, boiling point increases, meaning the liquid could get hotter than normal and remain a liquid.PV=nRT - pressure x volume = the number of moles x constant x temperature
