Properties of Matter

What is the best definition of physical properties?

• Physical properties can be observed without changing the identity of the substance.

• Physical properties describe how a substance changes into a completely different substance.

• Physical properties can only be observe with our physical touch.

• Physical properties are only observed when a new substance is formed.

This property of matter determines how easily a substance will dissolve in a liquid, such as water.

• melting point

• boiling point

• solubility

• viscosity

What two types of measurements make up DENSITY? 

• Mass and Volume
• Temperature and Mass
• Grams and Centimeters
• Volume and Weight

Which liquid is the least dense?

• Oil

• Water

• Syrup

• Plastic bottle

Jack has a rock. The rock has a mass of 14g and a volume of 2cm³. What is the density of the rock? (Density = Mass/Volume)

• 7 mL
• 7 g/cm³
• 28 g/cm³
• 1/7 g/cm³

If an object has a density of 0.6 g/mL and you put it into water, will it sink or float? (Hint: The density of water is 1 g/mL)

• sink

• float

True or False: The density of a specific type of material never changes making density an intensive property.

• True

• False

Calculate the density of the cube. (Density = Mass/Volume)

• 2 g/cm³
• 4 g/cm³

• 10 g/cm³

• 30 g/cm³

You calculated the density of an unknown substance to be 7.8g/cm³. According to the chart, which of the substances do you most likely have?

• Zinc

• Copper

• Tin

• Iron

If I cut a block of gold in half, what happens to its density?

• The density is cut in half because density depends on sample size.

• The density stays the same because density is an intensive property.

• The density doubles since density does not depend on sample size.

• The density is cut in half because density is an intensive property.
