Do gases have a volume? What is gas volume? How does volume affect the pressure of a gas? This means that if a gas is heated up and the pressure does not change , the volume will.

So for a fixed mass of gas at a constant pressure, volume ÷ temperature remains the same. One mole of any gas has a volume of dmor 20cmat rtp (room temperature and pressure). This volume is called the molar volume of a gas.

This equation shows how the volume of gas in dmat. Typically we can use the gas laws to calculate what volume a given amount of gas will occupy under a particular pressure. Can a gas have zero volume? Does a gas have a definite volume?

Compressing a gas does work on the gas and therefore increases its temperature. When the gas is first compressed it will have a pressure of 800kPa at some elevated temperature. As it cools, the volume decreases to the value that you want. Use the combined gas law because pressure, temperature and volume are changing. Molecules of a gas, like molecules of any substance, take up a certain amount of space.

So gas molecules can be measured by volume which is the distance (length, width, height) that the molecules. An inflated balloon holds the volume of gas blown into it. Gas does have volume.

Gases have lower density than other states of matter, such as solids and liquids. There is a great deal of empty space between. Eventually, if the gas is compressed enough, the molecules will be close enough to feel molecular forces and change to the liquid phase of matter. So, gas is compressible and does not have fixed. Boyle concluded that volume could only be inversely proportional to pressure for a fixed mass of gas at a constant temperature if gases contained particles that were moving around.

If you have the same number of particles, then the gas will have the greater volume. The particles of matter in the solid state are close together and fixed in place. The gas expands to fill its container. Mass is the actual amount of the gas in terms of say atoms or molecules. Thus, the average volume occupied by one molecule in the gas is larger than the corresponding volume occupied in the liquid by a factor of 1. Since volume varies as the cube of distance, the ratio of the mean separation distance in the gas to that in the liquid is roughly equal to the cube root of 60 or about 12.

These neutral gas particles only change direction when they collide with another particle or with the sides of the container. Gasses are made out of atoms. All atoms have mass. The volume is the space it takes up. Under these conditions, if two gases have the same volume , they must necessarily contain the same molecular quantities.

Volume and pressure are independent of one another. As the volume decreases so does the pressure. Which gas will occupy a greater volume (both at STP)? H2O vapour in a balloon of volume 4.
