What is the boiling point? Describe the change in energy.

The point at which a liquid changes into a gas; water's boiling point is 212 degrees F/100 degrees C. Energy goes up!

100

The state of matter of a material depends on its what?

Kinetic energy of the particles

100

What is evaporation?

When a liquid changes into a gas ONLY AT THE SURFACE. Energy increases!

100

How does volume affect pressure?

As volume goes down, pressure goes up. 

As volume goes up, pressure goes down.

They have an inverse relationship.

100

What happens to gas when heated? Describe the motion of the particles and describe what happens to pressure.

Pressure increases! Particles move farther apart.

200

What is the freezing point? Describe the change in energy.

The point at which a liquid changes into a solid. Energy goes down!

200

What happens to water vapor on a cool mirror?

Condensation. Energy goes down!

200

What is condensation?

When a gas turns into a liquid. Energy goes down!

200

What happens when gas particles are added?

Pressure increases!

200

Double Jeopardy!

What does decreasing volume do to pressure?

Increases the pressure! The particles are pushed closer together.

300

What is the melting point? Describe the change in energy.

The point at which a solid changes into a liquid. Energy goes up!

300

What is a change in state?

When a substance changes from a solid, liquid, or gas into another state.

300

What is melting?

When a solid turns into a liquid. Energy goes up!

300

What happens to pressure in a sealed container when a vacuum is added?

Pressure goes down!

300

What is the relationship between pressure and volume?

As volume goes down, pressure goes up. As pressure goes down, volume goes up.

400

What is the condensation point? Describe the change in energy.

The point at which a gas turns into a liquid. Energy goes down!

400

How does temperature affect states of matter?

Increasing temperature increases the kinetic energy of a substance and can cause it to change state. Decreasing temperature decreases kinetic energy of a substance and can cause it to change state.

400

What is freezing?

When a liquid turns into a solid. Energy goes down!

400

How does pressure affect boiling point?

Lower pressure lowers the boiling point. This is why pasta cooks at a lower temperature in Denver than it does at sea level.

400

What happens to a balloon when heated? Talk about the particle movement and discuss pressure and volume

Particle motion increases. Energy increases. Pressure increases. Volume increases.

500

Double Jeopardy!

What is the sublimation point? Describe the change in energy.

The point at which a solid changes directly into a gas. Energy goes up!

500

What creates pressure in a gas?

Increase in particle motion, decrease in the bonds that hold particles together; specific examples include an increase in temperature or a decrease in volume or an increase in number of particles.

500

What is deposition?

When a gas turns directly into a solid. Energy goes down!

500

Double Jeopardy! 

Why do tires lose pressure after a cold night? Describe particle motion and volume. What would happen to these tires if you drove in a very hot area?

A lower temperature lowers the motion of the air particles in the tire. The volume of the tire decreases. The pressure of the tire decreases. 

The particle motion would increase, the volume would increase, and the pressure would increase

500

How does a pressure cooker/instant pot work? Talk about pressure and temperature as the food cooks.

A pressure cooker increases the pressure and increases the temperature. Food cooks faster at a hotter temperature and higher pressure.
