Question

Water boils at 100 c degrees and turns into steam. Which similarities or differences are there between water at 100 c degrees and steam at 100 c degrees?
A. The particles will have more 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 as a liquid, but they will be moving faster 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 and will be moving at higher speeds as steam.

Answer 1

The correct choice is **D. The particles will have more space between them and will be moving at higher speeds as steam.**

### Explanation:
1. **Space Between Particles:**
- In the liquid state (water at 100°C), particles are relatively close together and have some interactions.
- In the gaseous state (steam at 100°C), particles are much farther apart, resulting in more space between them.

2. **Particle Movement:**
- In the liquid state, water particles move around but are limited by intermolecular forces.
- In the gaseous state, steam particles have enough energy to move freely and are not constrained by these forces, leading to increased speed.

So, steam not only has more space between particles but also the particles move faster compared to liquid water at the same temperature.
