Why does dew generally disappear when temperature rises during the day?
Answer and explanation
Correct answer: ओस की बूंदें वाष्पित होकर जलवाष्प बन जाती हैं
During the day, solar heating raises the temperature of the surface and the dew droplets. On receiving sufficient heat, the liquid water droplets evaporate into water vapour and mix with the air, so the dew appears to disappear. Condensation is the opposite process: it forms droplets from water vapour on a cool surface. Exam tip: the change of liquid water into water vapour is called evaporation.
