100
Anything that flows
What is a fluid?
100
These are the three states of matter.
What is a gas, liquid or solid?
100
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 float?

100
The circulatory system is an example of a _________ system.
What is a natural system?
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
A mechanical part that moves fluids through something
What is a pump?
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
Doing this to a gas makes this less viscous.
What is cooling the gas?
300
True or false If something floats, it is said to be buoyant.
True
300
A system that uses a compressed gas to do work
What is a pneumatic system?
400
The tendency of an object to rise or sink in a fluid.
What is buoyancy?
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?
400
As you sip juice from a straw you are creating _____ pressure in the container.
What is high pressure?
400
Squeezing an end of a toothpaste tube and it pushing out of the opening is an example of ______
What is Pascal's Law?
500
This states that when you apply pressure to a confined fluid, the fluid will send that pressure out in all directions at the same rate.
What is Pascal's Law?
500
When the temperature of a substance decreases, this happens to its volume.
What is decrease of volume or contraction?
500
For a substance to float in water it needs to have a density less than:_____.
What is 1g/mL?
500
Heating up a fluid creates a _____ pressure.
What is a lower pressure?
500
A system that uses a compressed liquid to do work.
What is a hydraulic system?
