Current Question (ID: 8228)

Question:

$\text{A gas cannot be liquefied if:}$

Options:

1. $\text{Forces of attraction are low under ordinary conditions}$
2. $\text{Forces of attraction are high under ordinary conditions}$
3. $\text{Forces of attraction are zero under ordinary conditions}$
4. $\text{Forces of attraction are either high or low under ordinary conditions}$

Solution:

$\text{Hint: In the case of Ideal gas, the force of attraction between molecules is zero.}$ $\text{Ideal gas molecules are separated from each other by large space and the actual volume of the gas molecule is negligible with respect to the volume of gas. Due to large intermolecular spaces, there is no force of attraction between the ideal gas molecules and they are completely independent of each other.}$ $\text{Hence, Ideal gas cannot be liquefied as its molecules have no forces of attraction.}$
