Question

1. particles in a gas are far apart relative to their size. this property would explain which of the following? gas particles are smaller than particles of a solid. gas particles are not attached nor repelled by other gas particles. gases are highly compressible. gas particles have low temperatures.

Explanation:

1. Analyze the first option: The distance between gas particles and their size doesn't imply gas particles are smaller than solid particles. Solid particles are close - packed, but particle size (mass/volume of the particle itself) and inter - particle distance are different concepts. So this option is incorrect.
2. Analyze the second option: The fact that gas particles are far apart relative to their size is not related to the attractive or repulsive forces between gas particles. The forces between gas particles are related to intermolecular forces, not the relative distance of particles to their size. So this option is incorrect.
3. Analyze the third option: If gas particles are far apart relative to their size, there is a lot of empty space between them. When pressure is applied, this empty space can be reduced, which means gases can be compressed easily (highly compressible). This is a direct consequence of the large inter - particle distance relative to particle size.
4. Analyze the fourth option: The temperature of gas particles is related to their kinetic energy, not the relative distance of particles to their size. So this option is incorrect.

Answer:

C. Gases are highly compressible.
