Models of Solids, Liquids, and Gases

Use the models to answer the question. Models are of solids, liquids, or gases. Which explanation best explains what is happening between the first model and the last model?

• Thermal energy is being added and this causes an increase in particle motion and the particles to move apart.

• Thermal energy is being added and this causes a decrease in particle motion and the particles to move apart.

• Thermal energy is being removed which causes an increase in particle motion and the particles to get closer together.

• Thermal energy is being removed which causes a decrease in particle motion and the particles to get closer together.

Which of the following is a property of a solid?

• The particles move around each other.

• The particles are spread apart.

• The particles move very quickly.

• They have a rigid, fixed shape.

Which of the following is a property of a gas?

• They have a rigid, fixed shape.

• Their particles move less than those of a solid.

• They take the shape of their container.

• They become liquids when they gain thermal energy.

Which of the following is a property of a liquid?

• They have particles that move faster than gas particles.

• Their particles move faster than solid particles, but slower than gas particles.

• They have particles that are fixed in place.

• Their particles move slower than solid particles.

When a solid has turned directly into a gas through the process of sublimation, we could say that ____.

• the thermal energy has been taken away

• the particles of the solid are moving at a slower speed prior to becoming a gas

• the particles of the solid are moving very quickly prior to becoming a liquid.

• the solid has become very cold

Scenario:  You get in your car on a cold winter morning.  The tire pressure warning light is on letting you know that the air in your car tires is low.  Later that afternoon, the weather is much warmer.  You get in your car again and notice that the warning light is no longer on because the air in your tires is no longer low. 

Using the models and explanations, choose the best one that explains why this happened.

• Model A represents the tires in the morning and Model B represents the tires in the afternoon.

• Model C represents the tires in the morning and Model B represents the tires in the afternoon.

• Model B represents the tires in the morning and Model D represents the tires in the afternoon.

• Model C represents the tires in the morning and Model D represents the tires in the afternoon.
