Physical Properties

A group of students were investigating density with a jar of water and oil with several objects dropped into the jar. They were given a toothpick, a marble and a large paper clip. Which prediction below do you think is correct?

• water is less dense than oil

• the large paper clip is less dense than oil

• the marble is less dense than oil

• the toothpick is less dense than the oil

. A student moves unknown matter from a half-full jar to another jar. The matter fills the same amount of space and takes the shape of the new jar. The student can classify the substance as —

• a liquid

• gas

• solid

• string

. If a box of wax crayons was left in a hot car all of the following could happen EXCEPT?

• The crayons could change shape

• The colors could mix together

• The wax could become a liquid

• The paper wrappers could melt

Which tools would be needed to measure the size and the mass of a wooden block?

• a stopwatch and a metric ruler

• a graduated cylinder and a thermometer

• a metric ruler and a balance

• a thermometer and a meter stick

A student reads the label on the bottle of salad dressing shown here. Why would the student shake the salad dressing well before using it?

• Vinegar and oil have different densities.

• Vinegar and oil both contain water.

• Vinegar and oil easily form a solution.

• Vinegar and oil are both liquids.
