States of Matter and Particle Motion

How do molecules in a solid differ from those in a liquid?

• Molecules in a solid are spread out and take the shape of their container, while those in a liquid are tightly packed.

• Molecules in a solid move freely and collide randomly, while those in a liquid are tightly packed.

• Molecules in a solid move very quickly, while those in a liquid are stationary.

• Molecules in a solid are tightly packed and vibrate in place, while those in a liquid are spread out and move freely.

What happens to particle speed and collision frequency as temperature increases?

• Particle speed decreases and collision frequency remains constant.

• Particle speed remains constant and collision frequency decreases.

• Particle speed increases and collision frequency increases.

• Particle speed decreases and collision frequency decreases.

What is the result of increasing the temperature of a liquid?

• The liquid turns into a plasma.

• The liquid turns into a solid.

• The liquid turns into a gas.

• The liquid remains unchanged.

In which states of matter do particle collisions occur?

• In solids, liquids, and gases

• In both gases and liquids

• Only in gases

• Only in solids

What happens to scent molecules when you spray perfume in a room?

• They remain concentrated in one area.

• They spread out evenly due to collisions.

• They sink to the floor.

• They disappear immediately.
