Carbon Dioxide, under pressure and cooled, becomes 'Dry Ice'. It takes on the appearance of a block of frozen water (ice).
Crystallines can liquefy under pressure if it is sufficiently high. Generally the opposite happens where they become more dense and compressed as the pressure increases.
When the pressure is released, some of the liquid will transition into a gas, cooling some of the liquid into dry ice frost or snow, which can be collected and pressed into pellets or blocks. This is similar to what happens when you get frost on the nozzle of a CO2 fire extinguisher. The freezing point of carbon dioxide is -109.3°F or -78.5° C, so dry ice won't stay solid for long at room temperature.

When a parcel of air is forced downward, atmospheric pressure increases, causing the air to become compressed and therefore the temperature is also raised.
The world cools. Any time you release a compressed gas the expansion of that gas causes a cooling effect. That is the same way an air conditioner works. If you take the valve core out of the stem on your car tire you will actually see frost accumulate on the end of the stem.
When carbon dioxide is compressed to atmospheric pressure, it becomes a supercritical fluid with properties of both gases and liquids. It is often used in industrial processes like extraction and as a solvent due to its unique properties.
It is compressed and occupies a smaller volume.
You become a human popsicle
When a fluid is compressed in a confined space, the pressure of the fluid increases. This occurs because the molecules of the fluid are being pushed closer together, leading to a higher density and thus an increase in pressure.
When air is adiabatically compressed, its pressure and temperature increase while its volume decreases. This occurs without any heat exchange with the surroundings.
When a fluid is compressed, the volume of the fluid decreases while the pressure and temperature increase. This leads to an increase in the density of the fluid.

Pressure (such as air in a balloon) can increase with higher temps and decrease with lower temps.
Its density increases.
They both release carbon dioxide,but at different temperatures
When air particles are compressed, the density is increased. There is more pressure within a region or within a container. There are more molecules in a given volume, and this can cause the air to heat up. - The pressure of the air increases, as does its temperature, as its volume decreases.
