10 Questions
The correct SI terminology for the absolute temperature scale is 'degrees Kelvin'.
False
On the Rankine temperature scale, the boiling point of water occurs at 671.67°R.
True
The formula to convert Fahrenheit (°F) to Rankine (°R) is °R = °F + 459.67.
True
Vapor pressure refers to the pressure exerted by a solid in thermodynamic equilibrium with its condensed phases.
False
If the air pressure inside an air parcel near sea level is 1000 millibars, and the parcel contains 21% oxygen, the partial pressure exerted by oxygen would be 210 mb.
True
The actual vapor pressure of water vapor in the air parcel is 100 mb if the total air pressure is 1000 mb.
False
The freezing point of water occurs at 451.67°R on the Rankine temperature scale.
False
On the Rankine temperature scale, the absolute zero point is at 0°R.
False
If an air parcel contains 78% nitrogen and has a total air pressure of 1000 mb, the partial pressure exerted by nitrogen would be 778 mb.
True
Saturation vapor pressure refers to the pressure exerted by a liquid in equilibrium with its vapor phase.
False
Learn about the concepts of actual vapor pressure, saturation vapor pressure, and relative humidity. Understand how relative humidity is calculated as a percentage of the air's water vapor content compared to its total capacity.
