Question

Which of the following substance has strongest interparticle forces?

• A. Steam
• B. Water
• C. Petrol
• D. Wax

Answer 1

The correct option is D

Wax

• There are three types of matter- solid, liquid and gas.
• In solid particles are closely packed with each other and there is least interparticle space between them.
• In liquid particles interparticle space is present between them.
• In gas interparticle space is maximum as comparatively liquid. As the particles are loosely packed in space.

Explanation for the correct answer-

Option (d) Wax is in solid state ,so its particles are closely packed with each other and least interparticle space between them. so it has strongest interparticle forces.

Explanation for the incorrect answer-

Option (a) Steam is in gaseous state, so interparticle space is maximum

Option (b) Water is in liquid state, so interparticle space is less than gaseous particles.

Option (c) Petrol is in liquid state, so interparticle space is less than gaseous particles.

Therefore option (d) Wax is the correct answer.
