Hard · Level 87 · evaporative cooling,dry air,latent heat
View options
  1. Because evaporation takes latent heat and cools air and surfaces
  2. Because water removes oxygen
  3. Because condensation always produces cooling
  4. Because evaporation does not occur in dry air
Hard · Level 87 · pre rainfall,humidity,weather feeling
View options
  1. Because relative humidity can be very high
  2. Because vapour in air is zero
  3. Because evaporation is always maximum
  4. Because air temperature is always below freezing
Hard · Level 87 · water vapour,clouds,condensation
View options
  1. Because cooling to condensation is required for cloud formation
  2. Because vapour always blocks light
  3. Because more vapour always prevents clouds
  4. Because clouds form only from dust
Hard · Level 87 · clear sky,dew,radiational cooling
View options
  1. It increases radiational heat loss from the Earth surface
  2. It heats the surface more from the Sun
  3. It removes all water vapour
  4. It stops air rising so temperature does not change
Hard · Level 87 · relative humidity,temperature,saturation vapour pressure
View options
  1. Because saturation vapour pressure changes with temperature
  2. Because temperature has no relation with vapour
  3. Because it measures only rainfall
  4. Because it is sea-level altitude
Hard · Level 87 · closed container,saturation,evaporation
View options
  1. Because air has lost capacity to accept additional vapour
  2. Because water temperature automatically becomes infinite
  3. Because vapour cannot exist in a closed container
  4. Because saturation has no relation with evaporation
Hard · Level 87 · fog,visibility,condensation droplets
View options
  1. Suspended tiny water droplets scatter light
  2. Invisible vapour increases light
  3. Fog is only dry dust
  4. Fog makes air a vacuum
Hard · Level 87 · reservoir,local humidity,evaporation
View options
  1. Because an open water surface is a continuous source of evaporation
  2. Because the reservoir completely dries air
  3. Because evaporation never occurs from land
  4. Because the reservoir increases salt in air
Hard · Level 87 · water cycle,evaporation,condensation
View options
  1. Evaporation takes water into air and condensation turns it into cloud droplets
  2. Both permanently destroy water
  3. Both form only groundwater
  4. Neither has any relation with rainfall
Hard · Level 87 · relative humidity,diurnal cycle,temperature
View options
  1. Rain is compulsory in afternoon and stops in evening
  2. Afternoon warming raises saturation capacity and evening cooling lowers it
  3. Vapour always becomes zero in evening
  4. Condensation nuclei disappear in afternoon
Hard · Level 87 · contact cooling,condensation,fog
View options

  2. Conversion of vapour into oxygen
  3. Beginning of condensation due to contact cooling
  4. Complete disappearance of air pressure
Hard · Level 87 · soil moisture,evaporation,low humidity
View options
  1. Because low humidity increases condensation
  2. Because vapour formation in soil is impossible
  3. Because air is already saturated
  4. Because hot dry air accepts more vapour from soil
