ICP Unit 3 Review

Liquids

• Have definite shape and definite volume

• Have definite shape and indefinite (not definite) volume

• Have indefinite (not definite) shape and definite volume

• Have both indefinite (not definite) shape and indefinite (not definite) volume

Which can you compress?

• solids

• liquids

• gasses

• solids & gasses

During a phase change, temperature ________________.

• Increases

• Decreases

• Remains the same

• Increases then decreases

Atoms in a gas

• move in straight lines until they run into the wall or another atom

• vibrate in fixed locations

• slide past one another

• don’t move at all

For which state of matter do the atoms stop moving?

• Solid

• Liquid

• Gas

• None of Them

What does Kinetic Theory say about all matter?

• Only liquids move

• Only gasses move

• It is all in constant motion

• Attractions keeps solids from moving

When a liquid turns into a gas,

• the particles speed up

• the particles slow down

• the particles stop moving

• the particles move at the same speed

What do we call the average kinetic energy of a substance?

• heat

• temperature

• energy

• melting

While water freezes,

• the energy of the particles increases.

• the energy of the particles decreases.

• the energy of the particles stays the same.

• the particles stop moving.

Students sitting in their desks (like they should) best approximates

• a solid.

• a liquid.

• a gas.

• all states of matter.
