Science Quiz on States of Matter

Which of the students' claims about the sand in the hourglass is correct?

• Julia claims that the sand is a liquid substance, because when it flows from the top bulb into the bottom bulb, the volume remains fixed.

• Anthony claims that the sand is a gas because the grains flow quickly, and do not create a fixed shape when they settle into the bottom bulb.

• Chase claims that the sand is a solid substance, because the individual sand particles are solids that do not change shape as they flow into the bottom bulb.

• Maria claims that the sand is a liquid substance, because when it flows into the bottom bulb, it settles to take the shape of the container.
