What is density?

• The weight of an object in air

• The amount of "stuff" in a certain amount of space

• The color of an object

• The temperature at which a solid turns into a liquid

Does the size/ amount of an object affect its density?

• Yes, it changes the density

• No, size only affects volume, mass, and weight

• Yes, it makes the object heavier

• No, it changes the color

What is the melting point?

• The temperature at which a liquid turns into a gas

• The temperature at which a solid turns into a liquid

• The temperature at which a gas turns into a solid

• The temperature at which a liquid turns into a solid
