Properties of Matter

If objects are classified on their ability to float or sink in a tub of water, which property is being used to classify the items?

• mass

• density

• weight

• volume

What is the density of an object that has a mass of 15g and a volume of 3cm³?

• 30 g/cm³

• 45 g/cm³

• 3 g/cm³

• 5 g/cm³

a cold metal spoon is placed in a cup of hot water for 3 minutes. When removed, the spoon feels warmer. How did the hot water affect the motion of the particles in the spoon?

• it caused the particles vibrated faster

• it caused the particles vibrated slower

• it caused the particles top stop moving

• it caused the particles to move closer together

Liquid A and liquid B are poured into the same container. Liquid B separates and stayed on top while liquid A remained on the bottom. Which explains why the two liquids separated into two distinct layers.

• they are different colors

• they have different volumes

• they have different densities

• they are in different states of matter

heat being added to a solid, turning it into a liquid

• boiling

• freezing

• melting

• condensing
