A mixture of ideal gases is cooled upto liquid helium temperature (4.22K)(4.22K) to form an ideal solution.
A.True
B.False
C.Ambiguous
D.Data insufficient

Explanation

Solution

The concept of ideal gas is hypothetical. It consists of randomly moving particles, in which there is no interaction between these particles.

Complete step by step answer:
Before proceeding towards the answer, we need to develop the basic concept of ideal gas, real gas and their properties.
An ideal gas is one that should follow all the assumptions of kinetic theory of gases, and thus it must follow the gas laws at all the range of temperature and pressure. They have definite mass and velocity, but do not have volume. It does not undergo condensation and has no triple point. Volume occupied by the gas in the container is negligible.
On the other hand, a real gas is something that does not abide by the gas laws, all standard values of temperature and pressure. It deviates from ideal behavior, when volume is increased. These gases have fixed mass, volume and velocity. Volume occupied by the gas in the container is not negligible.
In the real scenario, there is no such thing as an ideal or perfect gas. This concept is theoretical.
Real gases deviate from ideal behavior because of the following two assumptions of kinetic theory of gases- (1) volume of ideal gas compared to the container is negligible, but in the case of real gases, the particles consists of some significant volume; (2) in case of ideal gas, there is no interaction between the constituting gaseous particles, but in the real scenario, the particles of real gas do exert force on each other.
So, a mixture of ideal gases cannot be cooled upto 4.22K4.22K , i.e., liquid helium temperature to form an ideal solution, because there will be no force of attraction between the molecules. So, the given statement is false.

So, the correct option is B.

Note:
Because of the low boiling point of liquid helium, it finds its application in many cryogenic systems as a refrigerant, when temperatures below the boiling point of nitrogen are needed. It is also used in NMR spectrometers, as a source of conducting magnetic fields.
