The hot, desert air of the Sahara often contains ____ water vapor than the cold, polar air farther
north, therefore has a ____ specific humidity.
- more; higher
- less; higher
- less; lower
- more; lower
- less; similar correct answers more; higher
Suppose the dew point of cold outside air is the same as the dew point of the air indoors. If the
door is opened and cold air replaces some of the warm air, then the new relative humidity
indoors would be
- the same as before.
- impossible to tell from the information given
- zero
- higher than before.
- lower than before. correct answers higher than before.
The ratio of the mass of water vapor in a given volume (parcel) of air to the mass of the
remaining dry air describes the
- relative humidity.
- mixing ratio.
- water vapor content.
, - dew point.
- absolute humidity. correct answers mixing ratio.
Which of the following will increase the relative humidity in a home during the winter?
- turning on the oven
- taking a shower and letting the air circulate through the home
- increasing the temperature of the air inside the home
- increasing the thermostat setting
- sealing the house against drafts correct answers taking a shower and letting the air circulate
through the home
Condensation is most likely to happen when air ____ and the speed of the water vapor molecules
____.
- cools; decreases
- warms; decreases
- remains the same temperature; decreases
- warms; increases
- cools: increases correct answers cools; decreases
The lowest temperature that can be attained by evaporating water into the air is known as the
- wind chill temperature.
- wet-bulb temperature.
- frost point.
- heat index.
