Why does the pressure increase when the gas is compressed?

Because Volume decreased

boyle law

When we increase the force, the pressure increases. When the pressure increases the number of molecules in unit volume of gas increases and the density increases too. So the gas becomes compressed.

Because farting too much is a problem, and peer pressure can be an issue.

Pressure is caused by collision of the gas particles with the container wall. More specifically, it's due to conservation of momentum as the gas particles change direction. in any case, if you keep the same number of particles and decrease the volume, the number of collisions per area of the container wall increases. Therefore pressure increases.

Compression increases its volatility.

By definition, compression results in an increase in pressure. If it did not, there would be no compression.

Molecules of gas are in a smaller volume so they have more collisions.

Collisions create pressure.

you have the same amount of mass but in a smaller container. Its like compressing a spring. The amount of stuff in it is the same but it's smaller.
