First Quarter Test 2

Which of the following states of matter has particles arranged most closely together?

• Solid

• Liquid

• Gas

• All of the above

According to Kinetic Molecular Theory, what happens to the particles in a substance as its temperature increases?

• They move faster.

• They move slower.

• They stop moving.

• Their arrangement doesn't change.

What do you call the process of changing a solid into liquid by heating it?

• Melting

• Freezing

• Evaporation

• Condensation

In which state of matter do particles have the most freedom of movement?

• Solid

• Liquid

• Gas

• All of the above have the same freedom of movement.

What term describes the process of a liquid changing into a gas at its surface?

• Melting

• Freezing

• Evaporation

• Condensation

What happens to the particles of a substance during melting?

• Gain energy and move faster.

• Lose energy and move slower.

• Don't change their energy or arrangement.

• Change their arrangement but not their speed.

Which of the following is NOT a factor affecting condensation?

• Pressure

• Temperature

• The color of the surface

• Presence of water vapor in the air

What is the opposite process of freezing?

• Boiling

• Melting

• Evaporation

• Condensation

What happens to the particles as a gas cool down and condenses?

• Gain energy and move faster.

• Gain energy and move slower.

• Lose energy and move closer together.

• Lose energy but maintain the same spacing.

What process is involved in everyday fog formation?

• Melting

• Boiling

• Evaporation

• Condensation
