Water boils at 100 degrees Celsius and turns into steam. Which similarity or differences are there between the water at 100 degrees Celsius and the steam at 100 degrees Celsius?

Question

a. The particles will have more space between them as a liquid, but they will be moving at the same speed in both states,
b. The particles will have more space between them and will be moving at higher speeds as steam
c. The particles will have more space between them as steam, but they will be moving at the same speed in both states
d. The particles will have more space between them as a liquid, but they will be moving faster as steam

Answer 1

The correct answer is:

b. The particles will have more space between them and will be moving at higher speeds as steam.

In this explanation, at 100 degrees Celsius, the liquid water has particles that are close together, while in the steam phase, the particles are much farther apart. Additionally, the steam particles move more rapidly due to the energy added to them during the phase change, leading to higher speeds compared to the liquid water particles.
