According to Avogadro's law, a volume of a gas depends on

Avogadro's law states that equal volumes of gases at the same temperature and pressure contain the same number of molecules. This means the volume is directly related to how much gas there is (the amount of substance) when temperature and pressure are kept constant. So the key idea is that volume reflects the amount of gas only when temperature and pressure don’t change. The other factors—molecular weight and color—don’t determine the volume for an ideal gas, and temperature alone doesn’t fix the volume because changing temperature changes volume unless pressure is adjusted to keep it constant.
