Which would happen to the particles of solids, liquids and gases if they are heated?

• atoms move faster and eventually particles contracts or move closer

• atoms move faster and eventually particles expands or move apart

• atoms move slower and eventually particles contracts

• atoms move slower and eventually particles expands

Which of the following is NOT TRUE about solid structure?

• atoms are arranged in row

• atoms are held tightly together

• atoms are vibrating

• atoms move about and change places

Describe the changes in the particles of solids when heat is absorbed?

• The particles of solids move away from each other when heat is absorbed.

• The particles of solids move closer with each other when heat is absorbed.

• The arrangement of particles of solids remain the same when heat is absorbed.

• The arrangement of particles of solids are Not affected with heat and energy.

What do you call the process when solid turns into liquid?

• Evaporation

• Condensation

• Freezing

• Melting

What process occurs when liquid water changes into steam or vapor?

• Evaporation

• Condensation

• Freezing

• Melting

Which of the following statement explains the changes of steam or water vapor into clouds during condensation?

• When particles of steam releases energy, they move closer with each other and forms liquid particles during condensation.

• When particles of steam releases energy, they move away from each other and forms into liquid particles during evaporation.

• During the process of melting, the particles of steam absorbs heat energy.

• During the process of freezing, the particles of steam absorbs heat energy.

Which of the following shows how particles behave when heated?

Heat energy affects the changes that occur with the particles of substances. Which of the following is NOT TRUE?

• When particles of ice absorb heat, the particles move faster, and they expand

• When particles of liquid absorb heat, the particles move faster, and they turn into steam or vapor.
