Based on the kinetic molecular theory, which statement best explains why gases can be compressed more easily than solids or liquids?

• A. Gas particles have stronger attractive forces than solids.
• B. Gas particles have lower kinetic energy than those in solids.
• C. Gas particles are far apart with negligible intermolecular forces.
• D. Gas particles occupy a fixed position in space.

Answer: (C)

Verified step by step guidance

1. Recall the key postulates of the kinetic molecular theory, which describe the behavior of gas particles, including their motion, spacing, and interactions.
2. Understand that gas particles are much farther apart compared to particles in solids and liquids, meaning the volume of gas particles themselves is negligible relative to the space between them.
3. Recognize that because gas particles are far apart, the intermolecular forces between them are very weak or negligible, allowing the particles to move independently.
4. Consider that when a gas is compressed, the large amount of empty space between particles decreases, which is easier compared to compressing solids or liquids where particles are already closely packed.
5. Conclude that the statement 'Gas particles are far apart with negligible intermolecular forces' best explains why gases can be compressed more easily than solids or liquids.
