22

what is Dalton's Law

law stating that the total pressure exerted by a mixture of gases is equal to the sum of the pressure exerted by the individual gases if they were present alone in the container.

what is relative humidity

a gas that is not fully saturated, the ratio of it's actual water vapor content to it's saturated capacity at a given temperature.

31

what is surface tension

the tendency of a liquid to minimize the area of it's surface by contracting. This property causes liquids to rise in a capillary tube, effects the exchange of gases in the pulmonary alveoli, and alters the ability of various liquids to wet another surface.

32

what is thermal conductivity

measure of heat. four methods of heat transfer, conduction, convection, radiation, and evaporation.

33

What is turbulent flow

Fluid molecules forming irregular eddy currents in a chaotic pattern.

34

what is vaporization

is the change of state from liquid to gas. vaporization requires heat energy.

35

what is viscosity

is the force opposing a fluids flow.

36

what is water vapor pressure

the pressure exerted by water in it's gaseous state.

37

what is capillary action

a phenomenon in which a liquid in a small tube moves upward against gravity. Capillary action involves both adhesion and surface tension forces.

38

what are the gas laws

Charles, Daltons, Gay-Lussac, Bernoullis, Pousielles

39

does water vapor exert pressure

no

40

what is BTPS

Body Temperature Pressure Saturated

41

What is a Venturi Tube

a modified entrainment device which widens just after it's jet or nozzle, helps restore fluid pressure. Provides greater entrainment.

42

What is a Pitot Tube

Tube that restores fluid velocity, lessens the effect of downstream pressure on fluid entrainment.

43

47

What are state changes

melting, freezing and sublimation. Melting: the changeover from a solid to a liquid state, Freezing: The changeover from a liquid to a solid due to extreme cold temperatures. Sublimation: Transition from a solid to a gaseous state without becoming a liquid first. This occurs because the vapor pressure is low enough for the intermediate liquid not to appear. Dry Ice is an example of sublimation.
