Water boils at 100°C and turns into steam.

Question

Which similarities or differences are there between water at 100°C and steam at
100°С?
The particles will have more space between them as a liquid, but they will be moving faster as steam.
The particles will have more space between them as steam, but they will be moving at the same speed in both states.
The particles will have more space between them as a liquid, but they will be moving at the same speed in both states.
The particles will have more space between them and will be

Answer 1

To clarify the properties of water and steam at 100°C, let’s examine the key differences:

1. Phase: At 100°C, water exists as a liquid, while steam is its gaseous form.

2. Particle Arrangement: In liquid water, particles are closely packed together, allowing them to be close but still have some freedom of movement. In steam, the particles are much further apart compared to the liquid water state.

3. Particle Movement: The particles in steam move much faster due to the higher kinetic energy in the gaseous state.

Given these points, the correct statement from your options would be:

• The particles will have more space between them as steam, but they will be moving faster as steam.

This option correctly identifies that steam has particles that are more spread out and that those particles move faster compared to the liquid state of water at the same temperature.
