​ A substance is able to flow freely within a container.  What state of matter is the substance in?

• gas

• liquid

• solid

• plasma

​How are solids and liquids similar?

• ​Solids and liquids both take the shape of their container.

• ​Solids and liquids both have no definite shape.

• ​Solids and liquids both can not move freely.

• ​Solids and liquids are both more dense than gases.

​When heat is added to a liquid, what occurs?

• ​Liquid molecules begin to condense to form a solid.

• ​Liquid molecules begin to slow down to become a solid.

• ​Liquid molecules begin to spread out to become a gas.

• ​Liquid molecules being slow down to become a gas.

​Why do atoms in a solid still vibrate?

• ​Atoms in a solid do not vibrate.

• ​All solids have some thermal energy - causing atoms to vibrate against each other

• ​Some solids have some thermal energy, and some do not.
