Energy possessed by an object due to its position or arrangement.

The lowest temperature achievable, where molecular motion stops.

Energy of motion; more prevalent in gases than solids or liquids.

Formula: F = (1.8 × C) + 32 for temperature conversion.

The transition from solid to liquid as molecular kinetic energy increases.

Pressure exerted by a vapor in equilibrium with its liquid or solid phase.

A measure of a fluid's resistance to flow; thicker fluids have higher viscosity.

The cohesive force at the surface of a liquid that makes it behave like a stretched elastic membrane.

The process where a liquid turns into a solid by losing heat.

The process where a solid turns into a liquid by gaining heat.

The attractive force between like molecules.

The attractive force between unlike molecules.

The ability of a liquid to flow in narrow spaces against gravity.

The change of state from liquid to vapor, which includes boiling and evaporation.

The process when a liquid turns into vapor due to high kinetic energy overcoming pressure.

The process where a liquid changes to a gas at temperatures below its boiling point.

The invisible gaseous form of water that behaves like other gases.

The ratio of actual water vapor content to the maximum capacity, expressed as a percentage.

The amount of water vapor needed to achieve saturation at body temperature.

The law stating the total pressure of a gas mixture equals the sum of the partial pressures of individual gases.

The principle that the pressure of a gas inversely varies with its volume at constant temperature.

The pressure needed to maintain equilibrium at a substance's critical temperature.

The temperature above which a substance cannot exist as a liquid regardless of pressure.

An irregular, chaotic flow pattern in a fluid, unlike streamlined flow.

A smooth, orderly flow of fluid in parallel layers or streamlines.

As fluid flow increases, pressure and potential energy decrease.

The drop in pressure when a fluid flows through a constriction.

The tendency of a fluid to follow a curved surface.

The flow of electric charge from one point to another due to voltage differences.

The pressure exerted by a single gas in a mixture, calculated using the formula PO2 = 0.21 x 760 torr.

At constant temperature, the volume and pressure of a gas are inversely proportional; as pressure increases, volume decreases (P1 x V1 = P2 x V2).

At constant pressure, the volume of a gas is directly proportional to its temperature (V1/T1 = V2/T2).

When gas volume is constant, pressure and temperature are directly proportional (P1/T1 = P2/T2).

Combines Boyle's, Charles's, and Gay-Lussac's laws to relate pressure, volume, and temperature (P1V1/T1 = P2V2/T2).

Body Temperature and Pressure Saturated; used for gas volume under body conditions.

Factor used to convert gas volumes between different conditions, such as ATPD, BTPS, and STPD.
