Hard · Level 86 · high humidity,saturation,rain
View options
  1. High humidity and air close to saturation
  2. Completely dry air
  3. Zero water vapour
  4. Only polar ice
Hard · Level 86 · relative humidity,actual vapour,temperature
View options
  1. No, because different temperature means different saturation capacity
  2. Yes, because relative humidity is absolute vapour amount
  3. Yes, because every place has the same temperature
  4. No, because vapour has no relation with weather
Hard · Level 86 · surface area,evaporation,water molecules
View options
  1. Larger open surface area exposes more water molecules to air
  2. Larger surface area turns water solid
  3. Smaller surface area always causes more evaporation
  4. Surface area has no relation with water
Hard · Level 86 · water vapour,weather,latent heat
View options
  1. Because it is linked with clouds, rain, and latent heat exchange
  2. Because it is more abundant than nitrogen
  3. Because it removes gravity
  4. Because it dries oceans completely
Hard · Level 86 · cloud droplets,rainfall,condensation
View options
  1. Because they need coalescence or ice processes to grow to falling size
  2. Because droplets have no mass
  3. Because every droplet goes to space
  4. Because condensation is opposite to rain and unrelated
Hard · Level 86 · sweat evaporation,humidity,comfort
View options
  1. Because the evaporation gradient becomes weak
  2. Because vapour never forms on skin
  3. Because the body has no temperature
  4. Because moist air is always icy
Hard · Level 86 · temperature dew point spread,condensation,humidity
View options
  1. Because air is far from saturation
  2. Because vapour can never become liquid
  3. Because dew point has no relation with humidity
  4. Because higher temperature always increases condensation
Hard · Level 86 · diurnal variation,relative humidity,temperature
View options
  1. Afternoon temperature increases saturation capacity
  2. Vapour stops existing in the afternoon
  3. The Sun turns air into water
  4. Air pressure is always zero in the afternoon
Hard · Level 86 · moist air,density,water vapour
View options
  1. Because water vapour has lower molecular weight than average dry air
  2. Because water vapour is always solid
  3. Because moist air has no gas
  4. Because dry air has no gravity
Hard · Level 86 · coastal humidity,night cooling,relative humidity
View options
  1. Falling night temperature can bring air closer to saturation
  2. The sea disappears at night
  3. Vapour does not form at coasts
  4. Air contains only dust at night
Hard · Level 86 · saturation,rainfall,relative humidity
View options
  1. Because after saturation, enough droplet growth and uplift are still needed
  2. Because (100%) humidity means zero vapour
  3. Because rain occurs only in dry air
  4. Because saturated air cannot form clouds
Hard · Level 86 · cold region,evaporation,temperature
View options
  1. Because water molecules get less energy to become vapour
  2. Because ice contains no water
  3. Because air disappears in cold
  4. Because icy regions never have the Sun
Hard · Level 86 · vertical distribution,water vapour,atmosphere
View options
  1. Because main sources are surface and oceans, and cold upper air has lower capacity
  2. Because gravity increases aloft and destroys vapour
  3. Because vapour comes only from space
  4. Because temperature is always higher aloft
Hard · Level 86 · evaporation,boiling,water vapour
View options
  1. Evaporation occurs at the surface at any temperature, while boiling occurs throughout liquid at a fixed temperature
  2. Evaporation occurs only in solids and boiling in gases
  3. Neither requires energy
  4. Boiling occurs only in clouds
Hard · Level 86 · condensation,cold surface,misty glass
View options
  1. Because vapour in air condenses into tiny droplets on the cold surface
  2. Because glass turns vapour into dust
  3. Because air disappears on a cold surface
  4. Because the Sun hides in glass
Hard · Level 86 · humidity,heat index,sweat evaporation
View options
  1. Because sweat evaporation decreases and body cooling becomes weaker
  2. Because humidity turns the body into fire
  3. Because temperature cannot be measured in moist air
  4. Because vapour creates the Sun
Hard · Level 86 · evaporation,cool air,saturation
View options
  1. Because both energy and vapour accepting capacity will be low
  2. Because water availability stops evaporation
  3. Because cold air has no gas
  4. Because saturated air is dry
Hard · Level 86 · rising air,cooling,relative humidity
View options
  1. Because cooling reduces saturation capacity
  2. Because vapour immediately disappears
  3. Because air pressure always becomes zero
  4. Because rising does not affect evaporation
Hard · Level 86 · warm air,moisture capacity,condensation
View options
  1. If moisture is available, more vapour and stronger condensation may become possible
  2. Warm air always remains completely dry
  3. Clouds never form in warm air
  4. Warm air permanently stops rain
Hard · Level 86 · temperature inversion,fog,humidity
View options
  1. Because cold moist air gets trapped below and mixing is reduced
  2. Because inversion instantly makes air dry
  3. Because inversion turns vapour into soil
  4. Because the Sun goes inside the ground during inversion
