Condensation of water leads to the coolness of water vapour and converts it into water or ice due to cooling .So when the water vapour become cool it comes down from the clouds and attach in glass or other things.

Condensation

Condensation is the process by which water vapor in the air changes into liquid water. It occurs when warm air containing water vapor comes into contact with a cooler surface. In the early winter mornings, the air temperature is usually lower than the dew point temperature, causing condensation to take place. This is why we can see drops of water on the grass during these times.

Explanation:

1. Water Vapor in the Air
- The air around us contains invisible water vapor, which is water in its gaseous state.
- Water vapor is formed through various processes such as evaporation and transpiration.

2. Dew Point Temperature
- The dew point temperature is the temperature at which the air becomes saturated with water vapor and condensation begins to occur.
- As the air temperature decreases, it reaches a point where it can no longer hold all the water vapor it contains, resulting in condensation.

3. Early Winter Mornings
- During early winter mornings, the temperature drops significantly, especially during the night.
- The cooler air cannot hold the same amount of water vapor as the warmer air, causing the excess water vapor to condense.

4. Cool Grass Surface
- The grass surface is typically cooler than the surrounding air during the early winter mornings.
- When the warm air carrying water vapor comes into contact with the cool grass surface, the air cools down further, leading to condensation.

5. Formation of Water Drops
- As the air cools down and reaches its dew point temperature, the water vapor molecules slow down and come together to form liquid water droplets.
- These water droplets adhere to the surface of the grass, resulting in the appearance of drops of water on the grass.

Conclusion
In conclusion, the drops of water we see on the grass during early winter mornings are formed through the process of condensation. The cooler air temperature causes the water vapor in the air to reach its dew point temperature, leading to the formation of liquid water droplets on the grass surface.
