प्रश्न
Explain the different forms of condensation: fog, mist, and dew
उत्तर
Fog and mist are formed at night when the air cools below its dew point near the earth’s surface. Fog is denser than mist and often dangerous because it reduces visibility. Dew forms in winter when the temperature is very low, but not below 0°C.
