Tea is ______ than honey.

What is more viscous?

100
If the density of an object is less than the density of the fluid the object will do this.
What is rise?
100

In what states of matter can you find fluids?

Gases and liquids?

200
The resistance of a fluid to flow.
What is viscosity?
200
Particles are constantly in motion is one of the 6 main points of this.
What is the Particle Theory of Matter?
200
Doing this to a liquid makes the substance more viscous.
What is cooling a substance?
200
True or false: To predict whether or not an object will float in a fluid, all you need to know is the weight of the object.
False. You need to know its volume too
200

An important characteristic of fluids is that they can flow.  Fluids can do this because..

Particles in fluids can move around each other

300

The amount of mass in a certain volume.

What is density?

300

The particles of this state of matter are far apart.

What is a gas?

300

increases in flow rate = ________ in __________

what is decrease in viscosity?

300
True or false If something floats, it is said to be buoyant.
True
300

This explains why when you put your hand in a fluid particles move ____________ forces

What is attractive?

400

Fluid that has the particles the most spread out

What is gas?

400

When you do this to a liquid, the particles move faster and farther apart until it turns into a gas.

What is heating up a liquid?

400

Calculate the density of the following: A 2.0 mL sample of a liquid has a mass of 12g.

What is 6.0 g/mL?
