A golf ball and a ping-pong ball are about the same size. In other words, they have about the same volume. However, a golf ball has more mass than a ping-pong ball. What can you conclude from this information?

• A ping-pong ball contains more matter than a golf ball.

• A ping-pong ball has the same properties as a golf ball.

• A golf ball contains a smaller amount of mass per volume than a ping-pong ball.

• A golf ball has a greater density than a ping-pong ball.

Johnny accidentally drops his toy dinosaur into a graduated cylinder. The dinosaur has a mass of 20 grams and the water level in the cylinder rises from 51 ml to 56 ml. Determine the density of the toy dinosaur. (The formula for density is D = m/V)

• 0.5 g/l

• 55 g/ ml

• 4 g/ ml

• 2 g/ ml

Answer explanation

D = m/V

D = 20g / (56 ml - 51 ml)

D = 20/5

D = 4 g/ml

Using this density column, list the substances in order from LEAST dense to the MOST dense.

• Water - Oil - Air - Syrup

• Syrup - Water - Oil - Air

• Air - Oil - Syrup - Water

• Air - Oil - Water - Syrup

Some lakes, such as the Great Salt Lake, accumulate soluble minerals such as salt. In those lakes, people find it much easier to float than when they are in fresh water. Why is this the case?

• People displace a smaller volume of fresh water than salt water

• This effect is only imaginary because floating depends on the skill of people.

• Fresh water is denser causing people to sink.

• Salt water is denser than fresh water

According to the table, which of these substances is basic? (SC.8.P.8.8)

• rain water

• distilled water

• drain cleaner

• soda water

An extremely strong base would have a pH of:

• 1

• 7

• 9

• 14

How does the picture relate to the particles in a solid?

• The cars are driving fast and switching lanes like the particles in a solid.

• The cars are sliding past each other while driving the speed limit like the particles in a solid.

• The cars are moving so fast you cannot even see them like the particles in a solid.

• The cars are barely moving like the particles in a solid.

What happens when you add energy to a liquid? (SC.7.P.11.1)

• Melting and it will turn into a

  solid.

• Freezing and it will turn into a

  solid

• Evaporation and it will turn into a

  gas.

• Condensation and it will turn into a

  gas.
