Which state of matter typically has the highest density?

• Gas

• Liquid

• Solid

• Plasma

What does density primarily measure?

• The total mass of an object

• The amount of space an object occupies

• How tightly packed the molecules of a substance are

• The temperature of a substance

Two cubes, one made of copper and one of aluminum, have the exact same volume. Which cube has a greater mass?

• The copper cube

• The aluminum cube

• They have the same mass

• It depends on the temperature

An object has a mass of 10 grams and a volume of 5 mL. What is its density?

• 0.5 g/mL

• 2 g/mL

• 5 g/mL

• 10 g/mL

An object with a density of 0.7 g/mL is placed in water. What will happen to the object?

• It will float on the surface.

• It will sink to the bottom.

• It will be suspended in the middle of the water.

• It will dissolve in the water.
