Question

When a gas is transferred from a small container to a big container, it occupies all the available space. Choose the correct reason for this

• A. The particles of gas are free to move anywhere
• B. The particles of gas has fixed shape
• C. The particles of gas has strong interparticle force
• D. All of these

Answer 1

The correct option is A

The particles of gas are free to move anywhere

Correct option explanation:- (A)

(a) Gases have neither a fixed shape nor a fixed volume and have negligible interparticle force of attraction, so it can easily flow.

Incorrect option explanation:-

(b)Gases have neither a fixed shape nor a fixed volume.Hence, given option is incorrect.

(c) The particles of gas does not have strong interparticle force of attraction, hence given option is incorrect.

(d) Only option (a) is correct, hence all of these cannot be answer.

Final statement:- When gas is transferred from a small container to a big container, it occupies all the available space because gases have neither a fixed shape nor a fixed volume and have a negligible interparticle force of attraction, so it can easily flow. Hence, option A is correct.
