Answer 1

The correct response is:

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

Here's why:

1. Space Between Particles: In the liquid state (water at 100°C), particles are relatively close together due to intermolecular forces. In the gaseous state (steam at 100°C), particles are much farther apart because these forces are significantly weaker in gases.

2. Movement of Particles: In steam, the particles not only have more space but also have higher kinetic energy, which means they move faster compared to the liquid state.

An ice cube tray full of water is put into a freezer. Which energy change occurs in the particles in the water as it undergoes a phase change from a liquid to a solid?(1 point)
Responses

The potential energy increases due to the looser arrangement of the particles.
The potential energy increases due to the looser arrangement of the particles.

The potential energy increases due to the tighter arrangement of the particles.
The potential energy increases due to the tighter arrangement of the particles.

The potential energy decreases due to the looser arrangement of the particles.
The potential energy decreases due to the looser arrangement of the particles.

The potential energy decreases due to the tighter arrangement of the particles.

Answer 3

The correct response is:

The potential energy decreases due to the tighter arrangement of the particles.

Here's why:

• When water freezes and undergoes a phase change from liquid to solid, the particles lose kinetic energy and come closer together, resulting in a tighter arrangement.
• As the particles settle into a more ordered and stable structure (solid state), the potential energy of the system decreases. In the solid state, the molecules are more closely packed and have less potential energy compared to their arrangement in the liquid state.
