Clouds can only form where air is rising. When air rises it cools off, and this can cause water droplets to form, making clouds. So the reason that clouds can hold water droplets is because the air in clouds is rising, and the rising air keeps pushing the water droplets up.

Mainly spring and autumn. Time of day. When the sun rises and warms mountainous areas and basins, the sea of clouds disappears. A few extra items to pay attention too: weather, location: mountainous areas and basins, and there are a few conditions regarding the weather.
First of all, the droplets of water are very very small, smaller than the head of a pin. Because they are so small they are easily kept up by the rising air. So the reason that clouds can hold water droplets is because the air in clouds is rising, and the rising air keeps pushing the water droplets up.
How do clouds dissipate?
Clouds are composed of liquid suspended water droplets in about a 100% RH environment. That clouds dissipate is by (1) the temperature increasing, (2) the cloud mixing with drier air, or (3) the air sinking within the cloud. When the temperature increases, the air has a higher capacity to evaporate.
If a cloud is no longer developing and not adding additional condensational moisture, the drier environmental air will gradually erode the cloud. Instead of having a sharp very defined appearance, after mixing with environmental air the cloud will look wispy with edges that are not well defined.
Some environmental air does mix into the cloud mass. If a cloud is no longer developing and not adding additional condensational moisture, the drier environmental air will gradually erode the cloud.
What happens when a cloud’s temperature increases?
When a cloud’s temperature increases, evaporation occurs and reduces the liquid moisture content of the cloud. A cloud can be warmed by solar radiation and longwave emission from the earth’s surface. Daytime heating increases the capacity of the air to evaporate liquid water.
