In liquid water, the particles are farther apart and move more rapidly than in steam at 100ºC
In liquid water, the particles are farther apart and move more rapidly than in steam at 100ºC

In steam, the particles are closer together and move more slowly than in liquid water at 100ºC.

Answer 1

The correct response is:

Both states have particles with the same average kinetic energy, but in steam, the particles are farther apart and move more freely than in liquid water.

At 100ºC, both liquid water and steam have the same temperature, which means they have the same average kinetic energy. However, in the gaseous state (steam), the particles are much farther apart and have more freedom to move compared to the liquid state (water), where particles are closer together and experience stronger intermolecular forces.
