14. TRUE OR FALSE: The dew point temperature is a measure of the total amount of water vapor in the air.

15. TRUE OR FALSE: The dew point temperature is a measure of the total amount of water vapor in the air.

16. Water departments in many cities in the desert southwest encourage their customers to water lawns early in the day. This is because the relative humidity is at its HIGHEST LOWEST value in the morning and the rate of evaporation from wet soil will be relatively HIGH LOW. (choose one word from each pair)
