Relative humidity (RH) equation
Mass of H2O in air/Mass H2O that can fit in air
If there is a fixed amount of water in the air, and the air temperature decreases, how does the relative humidity change?
Temperature goes down, the relative humidity goes up.
The average kinetic energy of the gas molecules is a distribution, but the average KE depends only on ________
temperature
pressure =
force/area
Density =
mass/volume
The sum of the kinetic energy and potential energy is the ?
internal energy
______ is directly proportional to the average KE
Temperature
Exchange of sevo into body is _______ ? What law
Diffusion
Grahams law
the rate of effusion is ______ proportional to the square root of the molecular mass? What law?
inversely
Grahams
essentially states that the rate of diffusion of a gas across a permeable membrane is determined by the chemical nature of the membrane itself, the surface area of the membrane, the partial pressure gradient of the gas across the membrane, and the thickness of the membrane
Fick’s Law
Diffusion rate is inversely proportional to? (2)
- membrane thickness
- sq. root of the molecular weight.

directly
henrys
