States of Matter
100

 This state of matter has particles that move freely and fill the shape and volume of their container.

Gas

100

This state of matter has particles packed closely in a fixed shape and volume.

solid

100

This state of matter has a definite volume but takes the shape of its container.

Liquid

100

Name the three common states of matter covered in this game.

Gas, solid, liquid

200

Use a white board to draw what gas particles look like.

dots spread out and moving chaotically.

200

Name a solid in the room

Something that actually makes sense.


200

Use a whiteboard to draw particles in a liquid.

Particles somewhat close together but farther apart than in a solid.

200

Define phase change and give two examples.

A phase change is when energy is added to something and it goes from a liquid to Gas or, solid to liquid.

300

What is the relationship between heat and average kinetic energy of gas particles?

When the heat is added to a solid or liquid, energy is added to the particles and the solid becomes either a liquid or gas.

300

Explain how particle motion in a solid differs from particle motion in a liquid. (How are the particles moving in each state of matter?)

In a solid, particles are packed closely together and vibrate. In a liquid the particles are a bit more spread out but move around as a group.

300

When thermal energy is added to a liquid what happens to the particles and what state of matter will it change into.

The particles gain more energy and begin to move and bounce around (no screaming). It becomes a gas.

300

Match each phase change with whether it requires adding energy or removing energy: melting, freezing, evaporation

Melting: adding energy

Freezing: removing energy

Evaporation: adding energy

400

Use a white board to draw what happens when heat is added to a liquid.

Becomes a gas.

400

How does heating a solid make its particles move more and eventually turn into a liquid?

Adding heat (thermal energy) gives the particles kinetic energy and they spread out (melt) and turn into a liquid.

400

Use a white board to draw what happens when heat is added to a solid.

Becomes a liquid.

400

Describe in simple words what happens to particles when a liquid freezes into a solid (mention motion and energy).

When a liquid freezes, its particles lose energy, slow down, and settle into fixed positions so the substance becomes a solid.
