States of Matter Test - 3

The question is based on statement of Gay Lussac’s law-“ At constant temperature, the pressure of a given mass of a gas is directly proportional to its absolute temperature.”
mathematically; 
PαT (at constant temperature)
or P/T = constant

This question is based on statement of Avogadro's law that states 'Equal volumes of all gases under the same conditions of temperature and pressure contain equal number of molecules'.
V ∝ n (atconstantT and P)

PV=nRT is the correct Ideal Gas equation.

Here, P : Pressure

          V : Volume

          n  : Number of  Moles

           R : Universal Gas Constant

           T  : Temperature

It has comparatively more force of attraction than other gases

The question is based on the statement of Dalton Law of Partial pressures for Gases which states that total pressure exerted by mixture of non reacting gases is equal to the sum of partialpressure of individual gases.

The Kinetic Theory of Gases assumes that no intermolecular forces exerts between the gas molecules.

Real gases have intermolecular forces of interaction due to which there is a difference in the actual pressure values when compared to the ideal gases, the pressure is found to be less than the pressure of ideal gases under similar conditions, similar deviation occurs when the size of molecules is taken into account due to which volume correction is required.

Z=PV/nRT, is a correction factor which describe the deviation of real gas from ideal gas behaviour.  it is defined as the ratio of the molar volume of a gas to the molar volume of an ideal gas at the same temperature and pressure.

This question is based on understanding the concept of molecular interactions between molecule of real gases which is least at low P and High T condition. Thus under these conditions real gases behave as ideal.
