Question Analysis
This question evaluates the student's understanding of the phase change from gas to liquid (condensation) and the factors that influence this process.

Key Concept Explanation
The phase change from gas to liquid (condensation) involves the compression of gas particles, which reduces the distance between them. This reduction in distance increases the interparticle forces, leading to the formation of a liquid.

Step-by-step Solution
1. Identify the initial state: The gas has highly dispersed particles with weak interparticle forces and no fixed shape or volume.
2. Describe the compression process: When the gas is compressed, the space between the particles decreases.
3. Explain the effect on interparticle forces: As the distance between particles decreases, the interparticle forces become stronger.
4. Describe the effect on particle motion: The increased interparticle forces reduce the random motion of the particles.
5. Conclude the phase change: The particles are now hel...
