Consider the following statements:

  1. Dew point is defined as the atmospheric temperature below which water vapours begin to condense
  2. The dew point declines with the rise of the air in atmosphere

Which of the above statements is/are correct?

Answer: [C] Both 1 & 2

Both are correct statements
If the air temp increases, its ability to hold water vapour increases. Air temperature decreases with altitude and so decreases the dew point.
