Particles in a solid mostly do this

What is vibrate in place?

100

When particles move faster this kind of energy increases

What is kinetic energy?

100

Liquid to gas

evaporation

100

If temperature is going down over time, energy is being...

What is lost (removed)

100

Why does water boil at a lower temperature on a mountain?

What is lower air pressure?

200

This state has particles that are far apart and move freely

What is a gas?

200

Which has more kinetic energy, solid or gas?

What is gas?

200

gas to liquid

condensation

200

If you see bubbles in liquid this means what

What is boiling?

200

Why do pressure cookers cook food faster?

What is higher pressure raises boiling point?

300

A substance has definite volume but not definite shape

What is a liquid?

300

As temperature increases, particle motion does this.

What is increases?

300

What happens to particle number when water boils?

What is stays the same?

300

Evaporation happens where in a liquid.

What is at the surface?

300

Why does dry ice turn directly into gas?

What is sublimation?

400

In this state, particles are tightly packed but can slide past each other

What is a liquid?

400

Low kinetic energy particles behave like this state of matter

What is a solid?

400

During a phase change, temperature does this.

What is stays the same?

400

On a heating graph, a flat line usually means this.

What is phase change?

400

Why do particles spread out when a liquid becomes a gas

What is increases kinetic energy overcomes attraction?

500

Describe particle spacing and movement of gas

particles are far apart and move quickly/randomly
500

Put in order from lowest to highest energy.  solid, liquid, gas

solid - liquid - gas

500

Solid to gas

What is sublimation?

500

Between minutes where temperature stays constant but energy is added, what is happening?

What is a phase change? (like when it is melting or boiling)

500

At high altitude, hikers must cook food longer because...

What is water boils at a lower temperature so less energy is transferred?
