Question Analysis
This question assesses the student's understanding of how pressure affects the phase of a gas and the underlying reasons for this change.

Key Concept Explanation
Gases have large distances between particles and weak interparticle forces. When pressure is increased, the space between gas particles is reduced, bringing the particles closer together. As the distance decreases, the interparticle forces become strong enough to hold the particles together, leading to the formation of a liquid.

Step-by-step Solution
1. State that increasing pressure can cause a gas to liquefy.
2. Explain that increased pressure reduces the distance between gas particles.
3. Describe how the reduction in distance strengthens the interparticle forces, causing the gas to condense into a ...
