Practice questions
Why can sprinkling water in hot dry air make the environment feel cooler?Why can air feel heavy or sticky just before rainfall?Why is a clear sky possible even when water vapour amount is high?How does a clear sky help dew formation at night?Why is relative humidity called a temperature-dependent indicator?If air in a closed container is already saturated, why will adding more water immediately limit evaporation?What is the direct reason for reduced visibility during fog?Why can air above a reservoir be more humid than air over nearby land?What is the combined role of evaporation and condensation in the atmospheric water cycle?What may be the main reason for relative humidity decreasing in the afternoon and increasing in the evening?If moist air suddenly passes over a cold land surface, which process is expected first?Why can soil moisture decrease rapidly on a hot day with low relative humidity?Relative humidity can decrease even when the actual amount of water vapour in air remains the same. What is the deeper reason?When the difference between dew point and air temperature is very small, which conclusion is most appropriate?If an air mass is cooled without adding moisture, why does relative humidity increase?Why is the unsaturation of air important for the rate of evaporation?Which sequence is correct when rising air reaches the condensation level?Why are condensation nuclei decisive in cloud droplet formation?Under strong night-time surface cooling, in which condition is dew formation most likely?Why can specific humidity be considered a more stable measure than relative humidity?
