Step 1
Which particle model diagram shows a gas?
Answer
The correct answer is B.
In diagram B, the particles are spaced out and randomly distributed, which is characteristic of a gas. Unlike solids and liquids, gas particles have a lot of energy, allowing them to move freely and fill the entire space available to them.
In contrast:
- Diagram A shows particles packed closely together in a regular arrangement, indicating a solid.
- Diagram C also has particles close together, suggesting a liquid.
- Diagram D presents particles that are clustered but not flowing freely, again indicating a solid rather than a gas.
