Is fog evaporation or condensation?

Fog shows up when water vapor, or water in its gaseous form, condenses. During condensation, molecules of water vapor combine to make tiny liquid water droplets that hang in the air. You can see fog because of these tiny water droplets.

Does condensation cause rain?

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.

Which form of water is snow?

Snow, by a simple definition, is a group of loosely connected ice crystals; ice is the solid form of water. It is more than just frozen rain, which would be called sleet, because water vapor turns directly into ice, totally skipping the liquid phase.

Is snow a liquid gas or solid?

Snow and hail is a solid, sleet has solids within a liquid mass, and rain is liquid. Ask students if they can find the gas phase of water. They may not recognize that a cloud contains components of water in the gas phase. Clouds also have particles in it, which are in the solid phase.

Is snow ice or water?

Snow is a form of frozen water. It contains groups of ice particles called snow crystals. These crystals grow from water droplets in cold clouds. They usually grow around dust particles.

When perfume is sprayed in the air we are able to smell it but not see it because?

Answer. Explanation: When a perfume is sprayed in one corner of a room, or the fumes from a cooking vessel are released, then, being gaseous in nature, the molecules travel quickly through the entire room and the smell spreads through out the room. This process is called as diffusion.

How does liquid perfume turn into a gas?

The ethanol/water mixture, which is volatile, evaporates from the droplets within a few seconds, leaving behind a droplet of the fragrant compounds in the perfume. These compounds will also eventually evaporate to form a vapor of the fragrant molecules. * The vapor diffuses through the air, spreading the scent.

Does perfume evaporate?

It’s hard to believe fragrance can evaporate out of the small openings of most perfume bottles, but it does. That precious, expensive perfume belongs on your body, not in the air. Remember that each time you remove the cap, a bit of oxidation and evaporation may take place, so keep it on as much as possible.

Why is perfume a homogeneous mixture?

Perfumes are solutions. Solutions are often described as homogeneous mixtures because they have the same appearance and properties throughout the mixture.
