both temperature and number of molecules are constant and we only changing the volume which lead to change in pressure. Use the ideal gas law to calculate pressure change, temperature change, volume change, or the number of molecules or moles in a given volume.



Answer :

An ideal gas's equation of state is pV = RT 1. where p refers to gas pressure, V to volume, N to moles, R to the universal gas constant (i.e., 8.3144 j/(o K mole)), and T to the absolute temperature.

Equal VOLUMES of GAS contain the same amount of molecules with constant temperature and pressure.

The quantity of gas molecules present directly relates to the change in pressure of the gas if the temperature and volume remain constant. The pressure is inversely proportional to the volume if both the temperature and the total number of molecules in the gas stay constant.

Avogadro's law, which states that equal volumes of various gases contain an equal number of molecules, applies when temperature and pressure are the same.
