what is melting point
temperature at which the solid and liquid forms of a substance are in equilibrium.
what is radiation
heat transfer without direct contact.
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.
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.
what is thermal conductivity
measure of heat. four methods of heat transfer, conduction, convection, radiation, and evaporation.
What is turbulent flow
Fluid molecules forming irregular eddy currents in a chaotic pattern.
what is vaporization
is the change of state from liquid to gas. vaporization requires heat energy.
what is viscosity
is the force opposing a fluids flow.
what is water vapor pressure
the pressure exerted by water in it's gaseous state.
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.
what are the gas laws
Charles, Daltons, Gay-Lussac, Bernoullis, Pousielles
does water vapor exert pressure
what is BTPS
Body Temperature Pressure Saturated
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.
What is a Pitot Tube
Tube that restores fluid velocity, lessens the effect of downstream pressure on fluid entrainment.

what is absolute zero
the lowest possible temperature that can be achieved.
what is boiling point
the temperature at which it's vapor pressure exceeds it's atmospheric pressure.
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.
What is temperature
