Liquid water boils at 100°C and undergoes a physical change as it turns into steam (gas). Which statement below is true regarding water in these two states? (as a liquid and as a gas)

Question

particles in steam vs. particles in liquid water at 100 degrees C

(1 point)
Responses

The particles will have more space between them as a liquid, but they will be moving faster as steam at 100°C

The particles will have more space between them as steam, and they will be moving at the same speed in both states at 100°C.

The particles will have more space between them as a liquid, and they will be moving at the same speed in both states at 100°C.

Answer 1

The correct statement is:

The particles will have more space between them as steam, and they will be moving at the same speed in both states at 100°C.

In steam (gas), the particles are much further apart compared to liquid water, and they move faster due to the higher energy state. However, at 100°C, the average kinetic energy of the particles is the same for both the liquid and gas phases because they are at the same temperature.
