What happens to the gas volume at a given pressure?

Answer 1

The gas takes on the size and shape of the container it's in. So if you make the volume of the container smaller (compress it) the volume of the gas is smaller as well. However, this comes at a higher pressure exerted, so there is no spontaneous mass creation.

Well, by definition, compress means "to make smaller; to press or squeeze together; or to make something occupy a smaller space or volume." Therefore, the very word "compress" implies a decrease in volume. So if you wanted to know what happens when you compress a gas, you are squeezing it into a smaller space, or decreasing the volume.

If you were to let the gas maintain a constant temperature as you compress it, then pressure would increase. If you were to let the gas maintain a constant pressure, then temperature would decrease.

If you were to rephrase your question to "what happens to the volume of gas if put under pressure," then the gas' volume would decrease. For the temperature to remain constant and the pressure to increase, a gas must decrease in volume to occupy a smaller area.

Answer 2

At a constant temperature and amount, the volume and pressure of a gas are inversely related. So if the volume decreases, the pressure will increase. This is because there are more gas particles, therefore more collisions, therefore more pressure. (because pressure is caused by collisions).

Answer 3

If pressure increases, volume decreases.

If pressure decreases, volume increases.

If temperature increases, volume increases, and vice versa.

Answer 4

d = molar mass x p / RT

if the temperature increases the density decreases

Answer 5

As the pressure of a gas increases, the volume will decrease and vice versa.

Answer 6

As a gas is compressed, its volume will decrease. We will also see the density and the temperature of the gas rise as a result of the compression, too.

Answer 7

Gas expands by heating at constant pressure
