Q

Pascals principle

A

Principle stating that changes of pressure on the surface of a confined fluid are exerted equally throughout the fluid and at all points on the fluid’s container

17
Q

Positive buoyant

A

Floats

18
Q

Negative buoyant

A

Sinks

19
Q

Boyle’s law

A

Law stating that the volume of a fixed quantity of a confined gas is inversely proportional to its pressure when its temperature is held constant

20
Q

Charles law

A

Law stating that the volume of a fixed quantity of a confined gas is directly proportional to its absolute temperature when its pressure is held constant

21
Q

Bernoulli’s principle

A

Principle stating that total energy (represented by kinetic energy, potential energy, and pressure) for a confined ideal fluid flowing through a pipe is conserved at all locations within the pipe
