States of Matter and Particle Behavior

How are particles arranged in a solid?

• They are randomly spaced and move freely.

• They are arranged in a regular pattern and vibrate around fixed positions.

• They are close together but can roll past each other.

• They are far apart and move at great speeds.

How do particles behave in a liquid state?

• They are held in fixed positions and do not move.

• They vibrate around fixed positions.

• They stay close together but can roll past each other.

• They move at great speeds and are far apart.

What are the characteristics of gas particles?

• They are arranged in a regular pattern and vibrate around fixed positions.

• They are close together and roll past each other.

• They have little energy and are close together.

• They have a great deal of energy, move at great speeds, and are far apart.

What happens to the heat energy absorbed by water during boiling?

• It increases the water's temperature.

• It changes the water's state from liquid to gas.

• It makes the water particles vibrate more vigorously.

• It causes the water to expand.

Why does the temperature of a substance remain constant during melting or boiling?

• The substance is losing heat energy.

• The heat energy is being used to change the state of the substance.

• The particles stop moving during these processes.

• The substance has reached its maximum possible temperature.

When a solid is heated and its temperature rises, what happens to its particles?

• They change their size.

• They stop vibrating.

• They vibrate more vigorously around their fixed positions.

• They break free and move randomly.

What is the primary difference between boiling and evaporation?

• Boiling occurs at any temperature, while evaporation occurs only at the boiling point.

• Boiling happens from within the body of the liquid, while evaporation occurs from the surface.

• Evaporation is a faster process than boiling.

• Evaporation changes the state from liquid to gas, while boiling changes it from liquid to solid.
