Hint: Ideal gas is described as a gas that comprises a set of point particles that are moving randomly. The interactions between the particles happen through elastic collisions. The ideal gas equation is PV=nRT, Where, P stands for pressure, V stands for volume, n is mole number of electrons, R stands for gas constant and T stands for temperature.
Complete Step by Step Solution:
Let's discuss the given options one by one.
There is the absence of the force of attraction (intermolecular) in an ideal gas. Therefore, its liquefaction is not possible by applying low temperature and high pressure. Therefore, the statement given in option A is true.
As we discussed, in an ideal gas, there is an absence of interaction between the molecules. Therefore, the statement given in option B is true.
The ideal gas equation is PV=nRT. This indicates at any temperature, PV is proportional to the quantity of gas. Therefore, the statement given in option D is true.
All the molecules of an ideal gas move at different speeds. Therefore, the statement given in option C is wrong.
Hence, option C is right.
Note: It is to be noted that, the ideal gas law formula follows the absolute pressure of 105 Pa and the standard temperature is of 273.15 K. Under various conditions of temperature and pressure, many gases behave alike to an ideal gas.
