The correct Answer is:
To solve the assertion and reason question, we will analyze both the assertion and the reason step by step. ### Step 1: Analyze the Assertion **Assertion:** The gases show ideal behavior when the volume occupied is large so that the volume of the molecules can be neglected in comparison to it. - **Explanation:** In the context of ideal gases, the ideal gas law (PV = nRT) assumes that gas molecules have no volume and do not exert forces on each other. When the volume of the gas is large compared to the volume of the gas molecules, the volume occupied by the molecules themselves becomes negligible. Thus, the gas behaves ideally. ### Step 2: Analyze the Reason **Reason:** The behavior of the gas becomes more ideal when pressure is very low. - **Explanation:** At low pressure, gas molecules are far apart from each other, which minimizes intermolecular forces. This condition aligns with the assumptions of the ideal gas law, leading to more ideal behavior. Therefore, both the assertion and the reason are correct. ### Step 3: Determine the Relationship Between Assertion and Reason - While both the assertion and the reason are true, the reason does not directly explain the assertion. The assertion focuses on the volume aspect, while the reason focuses on the pressure aspect. ### Conclusion - **Final Answer:** Both the assertion and reason are correct, but the reason is not the correct explanation of the assertion.

Assertion: All molecules of an ideal gas more with the same speed. Reason: There is no attraction between the molecules in an ideal gas.

Gases deviate from the ideal gas behaviour because their molecules

When is deviation more in the behaviour of a gas from the ideal gas equation PV=nRT ?

The main reason for deviation of gases from ideal behaviour is few assumptions of kinetic theory . These are (i) there is no force of attraction between the molecules of a gas (ii) volume of the molecules of a gas is negligibly small in comparison to the volume of the gas (iii) particles of a gas are always in constant random motion .

Assertion : The lowest hypothetical or imaginary temperature at which gases are supposed to occupy zero volume is called absolute zero . Reason : Volume of the gas at -273 . 15 C^(@) becomes zero i.e. gas does not exist at this temperature .

Assertion: The heat absorbed during the isothermal expansion of an ideal gas against vacuum is zero. Reason: The volume occupied by the molecules of an ideal gas is zero.

Assertion: The heat absorbed during the isothermal expansion of an ideal gas against vacuum is zero. Reason: The volume occupied by the molecules of an ideal gas is zero.

Which of the following volume (V) –temperature (T) plots represents the behaviour of one mole of an ideal gas at one atmospheric pressure?

If pressure and temperature of an ideal gas are doubled and volume is halved, the number of molecules of the gas

Assertion: On compressing a gas to half the volume, the number of molecules is halved. Reason: The number of moles present decreases with decrease in volume keeping the pressure and temperature constant.
