Question

Responses

he particles in steam and water are different substances, and steam particles are closer together.
he particles in steam and water are different substances, and steam particles are closer together.

The particles are the same size, but steam particles are colder than liquid particles.

The particles are the same size, but steam particles are colder than liquid particles.

The particles in both are gas, but steam particles have more mass than liquid particles.
The particles in both are gas, but steam particles have more mass than liquid particles.

The particles have the same amount of energy, but steam particles are spaced farther apart.

Answer 1

The best response that accurately describes a similarity and a difference between the particles in liquid water at 100ºC and the particles in steam at 100ºC is:

The particles have the same amount of energy, but steam particles are spaced farther apart.

This statement correctly indicates that both water and steam are at the same temperature (100ºC), which means the average kinetic energy of the particles is the same. However, the arrangement and spacing of the particles differ: particles in steam (gas) are much farther apart than those in liquid water.
