Intermediate Activities: Air is a Fluid

1.	Every object on earth or in space can be classified as a solid, a liquid, or a gas. (Check the correct answer.)
	True False

2.	Solid objects have well-behaved molecules and atoms that line up in an even pattern and give the object a specific shape. (Check the correct answer.)
	True False

3.	A block of wood and a crystal of salt are solids. (Check the correct answer.)
	True False

4.	A solid has a fixed shape. (Check the correct answer.)
	True False
