States of Matter (Earth and Space Science)

Temperature is a measure of how much the atoms in a substance are moving. Why is a substance hotter in the gas state than in the liquid state?

• Atoms can move to change a liquid’s shape.

• Atoms can be compressed when in the gas state.

• Atoms move more freely in the gas state.

• Atoms move in the gas state but not the liquid state.

When frozen ice cream melts, the atoms in the ice cream

• move further apart.

• move closer together.

• become ions.

• become electrons.

A substance will take on the shape of an open container if it is a

• liquid

• plasma

• gas

• solid

A mass of charged ions that can expand out of an open container would be considered a

• gas

• solid

• liquid

• plasma

If a substance containing neutral atoms can be compressed a lot so that the atoms move closer together and the space between them decreases substantially, the substance is most likely a

• gas

• solid

• liquid

• plasma

If a substance containing charged ions and electrons can be compressed so that the particles have less space between them, the substance is a

• gas

• plasma

• solid

• liquid

The dots in these cylinders represent the shape and density of the particles in the different states of matter. Each dot represents a charged ion, so when two ions are together in a pair, they represent a neutral atom. Which container most likely contains a liquid?

• A

• B

• C

• D

When atoms get more and more energy, they can ionize. What can happen to a gas as more energy is added to its atoms?

• As the atoms move faster, the gas can change into a plasma.

• As the atoms move slower, the gas can change into a liquid.

• As the atoms move faster, the gas can change into a liquid.

• As the atoms move slower, the gas can change into a plasma.

A floating balloon can be formed when the substance helium is released from a compressed container into a flat rubber balloon. Then, the decompressed helium atoms expand and float up, making the rubber balloon expand around them and float with them. What is helium’s state when it does this?

• liquid

• solid

• gas

• plasma
