States of Matter Quiz

The particles within a substance are in constant motion. The particles in which of these substances have the lowest amount of kinetic energy?

• the wax of a candle at room temperature

• the water in a glass of ice water

• the steam from a cup of coffee

• the ice cube in a glass of tea

An element is a pure substance in which there are how many kinds of atoms?

• 2

• 4

• 3

• 1

Which of the following is NOT a method used to determine if a substance is a mixture or a pure substance?

• chemical separation

• evaporation

• straining with a sieve

• tweezers

Students are comparing two mixtures. The first mixture is of sand and water, while the second mixture is of salt and water.

Which of the mixtures is also homogeneous?

• Neither mixture is homogeneous.

• The sand and water mixture is homogeneous.

• The salt and water mixture is homogeneous.

• Both mixtures are homogeneous.

As liquid water boils, what happens to change the volume of the substance?

• As heat energy is taken away, the volume of the water becomes more definite.

• The heat energy causes the molecules to move more slowly and clump together, taking up less space.

• Heat energy causes the molecules to move faster, so they are farther apart and take up more space.

• The molecules grow larger and take up more space, so the volume increases.

Students were investigating mixtures. During the investigation, they were asked to mix four different types of substances. Which experiment result would show that a heterogeneous mixture was created?

• Results 1 and 2 

• Results 2 and 3 

   

• Results 1 and 3 

• Results 3 and 4

The chart below shows the densities of various substances. Which three statements are true? Select three correct answers.

• The unknown liquid is more dense than iron.

• If mercury was placed in the unknown liquid, it would float.

• Iron and germanium are less dense than the unknown liquid.

• Lead is more dense than the unknown liquid.

• If germanium were placed in the unknown liquid, it would sink.

A student adds glycerin, water, and cooking oil to a glass. Then the student puts a plastic ball in the glass. Which of these has the least density?

• water

• glycerin

• cooking oil

• plastic
