100

What happens if you pour fluid into a container?

It takes the shape of the container.

100
What kind of experiment can we do to measure viscosity?

Use a ramp and see how fast it reaches the bottom. You can also do something like drop something heavy into cups of each fluid and see how long it takes to reach the bottom.

100

What are the three states of matter?

100 bonus points if you can name another one.

Solids, liquids, gases, and (bonus!) plasma.

200

Out of solids, liquids and gases, which are fluids?

Liquids and gases.

200

What is viscosity?

How much a fluid resists flowing. (How thick or runny it is.)

200

What do we call it when liquid turns into a gas?

Evaporation

300

What are the three properties of fluids?

They flow, they spread out evenly when poured, and they exert pressure.

300

How does temperature affect viscosity?

The higher the temperature, the lower the viscosity.

300

What can we add or take away to change the state of matter?

Energy

400

What are the two most common fluids on Earth?

Air and water.

400

Does honey have a high or low viscosity?

High viscosity (flows slowly)

400

If we add heat, what happens to particles?

They have more energy and move faster and farther apart.

500

Does a fluid's volume change if you pour it onto the floor?

No, it always has the same volume.

500

Why do fluids have different viscosities? Name at least one reason.

The strength of attraction between the particles (how much the particles like to stick together), temperature, and the chemical composition of the fluid.

500

What is the standard state of matter?

The state it's in at room temperature.
