In which of the following case evaporation of water will be slowest?
  • A tray of water kept in sunlight
  • A glass of water kept in a room.
  • A kettle of water kept on a burner
  • A bucket of water kept on rooftop
Drops of water appear on outer surface of the glass containing water with ice because of
  • Evaporation
  • Condensation
  • Transpiration
  • Sublimation
Clouds are
