Fluid

A

The ability to flow because the atoms can past each other.

18
Q

Buoyant force

A

A force that pushes upward

19
Q

Pressure

A

Amount of force in a fluid

20
Q

Achimedies Principle

A

The upward force on an object is equal to the weight displaced

21
Q

Pascal’s Principle

A

A Change of pressure is transmitted to each part equally

22
Q

Pascals

A

Is the unit of pressure

23
Q

Viscosity

A

The resistance of flow in a liquid or gas

24
Q

Charles’s law

A

Fixed amount of pressure at a constant temperature . If the volume of the gas decreases the temperature will increase.

25
Q

Boyle’s law

A

Fixed amount of pressure at a constant temperature. The volume of a gas will increase as the pressure decreases. (P1)V1=(P2)V2

26
Q

Gay-lassac’s law

A

The pressure of a gas increase with the temperature as long as the volume remains the same.
