• Closedly packed but not in an orderly manner

• Particles are far apart

• Particles are fast

How would you classify water?

• vapor

• ice

• liquid

• steam

Which of the following correctly describes the attraction force between particles in solid matter?

• Particles are far apart and experience weak forces.

• Particles are tightly packed and experience strong attractive forces

• Particles move freely and do not interact with each other

• Particles are not held together by any forces.

Can you name a common solid and describe its properties?

• Oxygen is a solid at room temperature.

• Granite is a liquid.

• Sugar is a gas when heated.

• Table salt (sodium chloride) is a common solid.

What is the state of matter of ice?

• liquid

• gas

• plasma

• solid

How do you change a liquid into a gas?

• Freeze the liquid.

• Add salt to the liquid.

• Apply heat to the liquid.

• Stir the liquid vigorously.

Which state of matter that have weak attraction force between the particles?

• Solid

• Gas

• Liquid

How can you illustrate the change from solid to liquid?

• The change from liquid to solid is called freezing.

• The change from liquid to gas is called evaporation.

• The change from solid to gas is called sublimation.

• The change from solid to liquid is called melting.

Which of the following best describes the freezing process?

• Freezing occurs when a liquid turns into gas due to an increase in temperature

• Freezing occurs when a solid turns into a liquid due to a decrease in temperature

• Freezing occurs when a liquid turns into solid due to a decrease in temperature

• Freezing occurs when a gas turns into a liquid due to an increase in temperature

Which of the following are examples of sublimation?

• Dry ice (solid carbon dioxide)

• Ice melting into water

• Snowflakes forming directly from water vapor

• Water turning from liquid to gas
