Density Quiz Review 2024

When a liquid or gas is hot, is it more or less dense?

• Less dense
• More dense
• The same density
• Variable density depending on pressure

What happens to the liquid or gas that is cool/cold?

• Cool or cold liquids and gases may sink

• Cool liquids and gases will stay exactly where they are

• Cool or cold gases move up and down over and over.

• Cold liquids and gases may rise.

When an object is very dense, what do the particles look like?

• The particles are spread far apart.
• The particles are in a liquid state.
• The particles are in a gaseous form.
• The particles are closely packed together.

In a container filled with liquids of different densities, where ould the most dense liquid be?

• At the top of the container
• In the middle of the container
• At the bottom of the container
• Floating on the surface of the liquid

The formula of density is

• Density = mass/volume
• Density = mass - volume
• Density = mass + volume
• Density = volume/mass

The density definition that we used IN CLASS is

• How much mass there is in the bottom of the container

• How tightly packed or spread out the particles are in a given volume.

• How much volume is in a given mass

• How mass times volume equals what is in the container

As material is cooled, what happens to its density?

• Density decreases.

• Density remains constant.

• Density fluctuates randomly.

• Density increases.

Which liquid is more dense than yellow?

• Blue

• Red

• Green

• Red and Green

In our straw experiment, when we put two liquids in the straw and they layered, it meant that the liquid on the bottom of the straw was MORE dense than the one on top.

• true

• false

The object on the right is more dense than the one on the left.

• true

• false
