What is necessary for water vapor to condense forming a cloud?

What is necessary for water vapor to condense forming a cloud?

Clouds form when the invisible water vapor in the air condenses into visible water droplets or ice crystals. For this to happen, the parcel of air must be saturated, i.e. unable to hold all the water it contains in vapor form, so it starts to condense into a liquid or solid form.

What does water vapor need to condense and form clouds or fog?

Fog develops when air having a relatively high humidity comes in contact with a colder surface, often the Earth’s surface, and cools to the dew point. Additional cooling leads to condensation and the growth of low-level clouds. Fog that develops when warmer air moves over a colder surface is known as advective fog.

What does water vapor need to condense?

Condensation is the term for water changing state from a vapor to a liquid. The process requires the presence of water vapor in the atmosphere, falling temperature and the presence of another object for water vapor to condense around.

What two conditions must be present for water vapor to condense and form rain?

Solution: 1) The air must contain water vapor that can precipitate, 2) the moist air must cool down in order to release water in liquid form, and 3) there must be condensation nuclei for water vapor to condensate on.

How are clouds formed Class 9?

How are clouds formed? Ans. During day time water from different sources like pond, lake, river, sea, well etc get evaporated and this water vapour rises up with the hot air. At a particular height the air cools and the water vapour condenses to form minute droplets and form clouds.

What are the 4 conditions that must exist for precipitation to occur?

What needs to be present for condensation to occur?

Two things must be present for condensation to occur: warm moist air, and cool surface temperatures below the dew point. The proper control of these two factors can minimize condensation.

How does water vapor form into a cloud?

Water Vapor Condenses to Form a Cloud It’s easier for water vapor to condense into water droplets when it has a particle to condense upon. These particles, such as dust and pollen, are called condensation nuclei. Eventually, enough water vapor condenses upon pieces of dust, pollen or other condensation nuclei to form a cloud.

How are the different types of clouds formed?

And why do different types of clouds form? The water or ice that make up clouds travels into the sky within air as water vapor, the gas form of water. Water vapor gets into air mainly by evaporation – some of the liquid water from the ocean, lakes, and rivers turns into water vapor and travels in the air.

Which is an example of the condensation of water?

Condensation is the process of water vapor turning back into liquid water, with the best example being those big, fluffy clouds floating over your head. And when the water droplets in clouds combine, they become heavy enough to form raindrops to rain down onto your head.

Why are clouds made of water and ice?

Clouds form when the air cools below the dewpoint, and the air can not hold as much water vapor. Clouds are made of water droplets or ice crystals that are so small and light they are able to stay in the air. But how does the water and ice that makes up clouds get into the sky? And why do different types of clouds form?
