Fluid

Question 1

Matter

Answer 1

Anything that has mass takes up space and is made of particles.

Question 2

Solid

Answer 2

The state of matter in which the substance has a definite volume and shape. Particles can not move around one another.

Question 3

Liquid

Answer 3

The state of matter in which the substance has a definite volume but no definite shape. Particles move freely.

Question 4

Gas

Answer 4

The state of matter in which the substance has neither a definite volume nor a definite shape. Particles move rapidly and freely.

Question 5

Fluid

Answer 5

Any substance that flows. It can be a liquid or a gas.

Question 6

Viscosity

Answer 6

The measure of how fast a fluid will flow; the “thickness” or “thinness” of a fluid.

Question 7

Flow Rate

Answer 7

The volume of fluid that passes a point in a pipe or tube in a certain amount of time.

Question 8

Mass

Answer 8

The amount of matter in a substance.

Question 9

Weight

Answer 9

The force of gravity exerted on a mass.

Question 10

Density

Answer 10

The amount of mass in a certain unit volume of a substance (mass divided by volume).

Question 11

Average Density

Answer 11

The total mass of an object is divided by the total volume.

Question 12

Buoyancy

Answer 12

The tendency to rise or float in a fluid.

Question 13

Force

Answer 13

A push or pull, or anything, that can cause a change in motion.

Answer 17

The ability to be squeezed into a smaller volume.

Question 18

Compressible

Answer 18

Capable of being squeezed into a smaller volume.

Question 19

Incompressible

Answer 19

Not capable of being squeezed into a smaller volume.

Question 20

Hydraulics

Answer 20

The study of pressure in liquids.

Question 21

Pneumatics

Answer 21

The study of pressure in gases.

Question 22

Pump

Answer 22

A device that moves a fluid through a hose, pipe or into a container.

Question 23

Compressor

Answer 23

A device that compresses air.

Question 24

Balanced Forces

Answer 24

When all the forces on an object are equal and opposite, such that the movement will not change.
