Physical Properties of Matter

Mike fills a graduated cylinder with 30 mL of water. He then drops a 50 g rock into the cylinder. The water rose to 35 mL as shown in the picture. What is the density of the rock?

Remember D= m/v

• 10 g/mL

• 6 g/mL

• 15 g/mL

• 12 g/mL

Look at the picture. Which substance would be the least dense?

• Blue substance

• Orange substance

• Black substance

• Red substance

What is the volume of the rock? The water level is displaced from 20 mL to 23 mL with the rock.

• 3 mL
• 23 mL
• 20 mL
• 43 mL

In which state does matter completely fill its closed container?

• Gas
• Liquid
• Solid
• Ice

What is a solvent

• A liquid that will dissolve a solid solute

• Another word for solution

• A thing that make drinks change colour

• Usually the solid about to be dissolved

The substance being dissolved in a solution is the?

• solution

• solute

• solvent

• mixture

Beaker#1 has 100 mL of water and Beaker#2 has 500 mL of water. In order to identify common physical properties between both substances, both substances were heated to 100 oC. After a few minutes both substances begin to bubble at the same time.

• This experiment provides evidence that the boiling point is a property independent of the amount of water.

• This experiment provides evidence that the boiling point does change based on sample size.

• This experiment provides evidence that the volume remains constant in the samples.

• This experiment provides evidence of a change in the volume of the samples.

Which would be the most useful for identifying an unknown substance?

• Weight because it does not depend on sample size

• volume because it will depend of the size of the sample

• mass because it will depend on the size of the sample

• density because it does not depend on sample size

which substances could be grouped or sorted based on their physical property of MAGNETISM? Which group would magnetic?

• Iron, Nickel, Cobalt

• Iron, Nickel, Plastic

• Iron, Nickel, Glass

• Iron, Nickel Wood
