	The highest relative humidity of the day is most likely to occur in the mid-afternoon.

	True False

	Vapor pressure is that part of the total atmospheric pressure attributable to its water vapor content.

	True False

	Assuming no additional water vapor is added to the air, increasing the air's temperature will increase the relative humidity.

	True False

	Relative humidity is a ratio of the air's actual water vapor content compared with the amount of water vapor required for saturation at that temperature (and pressure).

	True False

The following graph illustrates the water vapor capacity of a kilogram of air at various temperatures (g/kg).

Select the correct point on the graph where air containing 1 gram of water will have the indicated temperature.

Concept Quiz 2

If the air temperature remains constant, evaporating water into the air will __________ the relative humidity and __________ the dew point.

The highest relative humidity of the day is most likely to occur in the mid-afternoon.

Vapor pressure is that part of the total atmospheric pressure attributable to its water vapor content.

Assuming no additional water vapor is added to the air, increasing the air's temperature will increase the relative humidity.

Relative humidity is a ratio of the air's actual water vapor content compared with the amount of water vapor required for saturation at that temperature (and pressure).

The following graph illustrates the water vapor capacity of a kilogram of air at various temperatures (g/kg).Select the correct point on the graph where air containing 1 gram of water will have the indicated temperature.
