The state of matter that shows the largest change in volume when warmed or cooled is gas. Liquids and solids increase and decrease in volume in response to temperature change as well, but not to the same magnitude as gases.

the volume or mass of the matter. it can change states such as solid liquid or gas, which would be deemed to be the same chemical identity, but a different state of matter
Thermal expansion is the tendency of matter to change in volume in response to change in temperature. During thermal expansion, the density of a substance decreases as its volume increases. Volume is the space occupied by a body. So, when a substance expands on heating, it will occupy more space or will have more volume. But its mass does not change because the amount of matter contained in a body cannot change. Therefore, mass divided by increased volume gives a decreased density.
Matter changes both its shape and volume when it is in a gaseous state. Imagine oxygen: if you have a syringe full of oxygen, the oxygen is in the shape of the syringe, but if you let it out, it would readily lose this shape as it escaped into the environment. If you do not let it out, and instead push the syringe, you are compressing the oxygen; in other words, you are making the volume of the oxygen smaller by making it more dense. Oxygen, as with any other gas, does not have a fixed shape or volume.
take up space and have particles
The volume of a gas is subject to change with temperature and pressure.

Conntraction
The matter that can change shape and volume is gas.
Mass :/
Assuming that pressure and the amount of matter are constant (meaning they do not change), volume will increase as temperature increases.
A solid has a definite shape and volume.
gas
gas
it is a solid
Volume!
Liquids. By assuming that temperature and pressure are constant so that volume does not change.
Changes in the states of matter - or phase changes - do entail changes in volume.
