Humidity, evaporation, and condensation
Practice questions
What are two major ways to saturate air before condensation?Why are evaporation and condensation complementary in the water cycle?If air temperature rises while the amount of water vapour remains the same, what will happen to relative humidity?Why does condensation become more likely when air approaches its dew point temperature?On a desert day the temperature is very high but relative humidity is low. What is the main reason?Why can coastal air become saturated quickly even when daytime evaporation is high?If relative humidity is 90 percent why is the evaporation rate generally low?Wet clothes dry faster in strong wind. What is the most appropriate humidity-related reason?Why is dew formation more likely in a valley at night?In (RH=\frac{e}{e_s}\times100), what does (e_s) mean?In which situation can condensation be visible even without rainfall?What happens to water vapour when saturated air is cooled further?Why can local humidity be higher in a forest than in an open dry area?Why can mist or fog form when warm moist air moves over a cold surface?Why does relative humidity describe weather comfort better than absolute humidity?On a hot and humid day sweat dries slowly. What is the main geographical reason?If two places have the same actual water vapour but one is cooler, why will relative humidity be higher there?What is the importance of tiny dust or salt particles in cloud formation?Why does condensation occur in moist air rising along a mountain slope?In still air the rate of evaporation may gradually decrease. What is the main reason?
