Question

What causes gas pressure?

Answer 1

Hint :We know that the If we know whether the gas is ideal or pressurized, we can predict the behavior of their intermolecular attractive forces, and the volume occupied by those gases within a system. An Ideal gas as the names go behaves ideally, under any given temperature and pressure.

Complete Step By Step Answer:
If we know whether the gas is ideal or pressurized, we can predict the behavior of their intermolecular attractive forces, and the volume occupied by those gases within a system. An Ideal gas as the names go behaves ideally, under any given temperature and pressure.
There are three ways to increase the pressure:
Add more gas. More molecules mean more collisions. Like blowing more air into a balloon, the walls of the balloon get tighter.
Decrease the volume. Less space means less room for the atoms to move in and this will lead to more collisions and more pressure.
Increase the temperature. More energy means the atoms will move faster and will collide more often, more collisions and more pressure.
A pressurized opposite does not follow the gas law under a wide range of temperature and pressure, and it also disobeys the kinetic gas equation. E.g., if we compress a pressurized gas, the pressure will increase between the gas molecules, which will result in the dominance of attractive forces, and the gas will convert into liquid (condensation), which is contradictory to the “no attractive forces” statement by the kinetic theory of gases. There are two conditions under which a pressurized gas deviates from the ideal gas behavior; these are Low temperature and High pressure.

Note :
The concept of pressurized gas is hypothetical means there is no such gas which can show ideal behaviors under a wide range of temperature and pressure. However, a pressurized gas can show ideal behavior for a shorter range of temperature and pressure, meaning at low pressure and high temperature a pressurized gas can show ideal behavior.
