When water vapor in the air comes into contact with something cool, such as the outside of a cold glass of lemonade, its molecules slow down and get closer together. When that happens, the gaseous water vapor turns back into liquid water droplets. That’s condensation!

Winter condensation occurs on the inside of windows, while summer condensation occurs on the outside of windows.

Condensation is the process by which water vapor in the air is changed into liquid water. As condensation occurs and liquid water forms from the vapor, the water molecules become more organized and heat is released into the atmosphere as a result.

The most common example of condensation is a cold glass of water on a hot day. The cold liquid is on the inside of the glass, but there are also beads of water on the outside of the glass. This is not the same water.

Visible and Concealed Condensation 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.

The factors governing condensation

• The water vapour content of the air.
• Inside room temperature.
• Outside temperature.
• Internal and external temperature variation.

Condensation occurs when warm air collides with cold surfaces, or when there’s too much humidity in your home. When this moisture-packed warm air comes into contact with a chilly surface, it cools down quickly and releases the water, which turns into liquid droplets on the cold surface.

When air rises into the low-pressure region of the upper troposphere, it expands. Because it is expanding without absorbing additional energy from its surroundings, it gets colder. If the air contains water vapor, the water vapor also gets cooler, which causes it to condense into tiny liquid droplets.

Removing energy (cooling) increases the rate of condensation This is because a lower temperature means that more molecules are moving more slowly. If molecules move slower, they are more likely to attract and change their state from a gas to a liquid.

How does the temperature affect condensation? The amount of water vapor air can hold is directly related to the air temperature. Warmer air can hold more water vapor than cooler air. When warm air is cooled it looses its capacity to hold water vapor and, if it cools enough, it will begin to condensate.

The latent heat of condensation is defined as the heat released when one mole of the substance condenses. The temperature does not change during this process, so heat released goes directly into changing the state of the substance. The energy released in this process is called heat of condensation.

Latent heat of evaporation is the energy used to change liquid to vapor. IMPORTANT: The temperature does not change during this process, so heat added goes directly into changing the state of the substance. Latent heat of condensation is energy released when water vapor condenses to form liquid droplets.

Condensation is the change from a vapor to a condensed state (solid or liquid). Evaporation is the change of a liquid to a gas.

Let’s read further to know about the everyday life examples of evaporation.

• Drying Clothes under The Sun.
• Ironing of Clothes.
• Melting of Ice Cubes.
• Preparation of Common Salt.
• Evaporation of Nail Paint Remover.
• Drying of Wet Hair.
• Drying up of Different Water Bodies.
• Evaporation of Sweat from Body.

Lesson Summary Next, it moves through evaporation, or the process by which water is converted from its liquid state to a gaseous state called water vapor. This is followed by condensation, which is the process by which water vapor is changed back into liquid water.

Evaporation in Daily Life One important example of evaporation is sweating. The sweat requires energy to evaporate off of your skin. It gets that energy from the excess heat your body is producing, in turn causing you to cool down.

Rain occurs when too much water condenses around atmospheric dust particles for the water to remain in the sky in the form of clouds. Other forms of precipitation, such as snow and sleet, are also related to condensation. Snow and sleet are frozen droplets of water.

Evaporation is a very important part of the water cycle. Once water evaporates, it also helps form clouds. The clouds then release the moisture as rain or snow. Condensation is crucial to the water cycle because it is responsible for the formation of clouds.

— sweat glands start making sweat. Sweat is also known as perspiration (say: pur-spuh-RAY-shun), and it is made almost completely of water, with tiny amounts of other chemicals like ammonia (say: uh-MOWN-yuh), urea (say: yoo-REE-uh), salts, and sugar. (Ammonia and urea are left over when your body breaks down protein.)

Sweat makes your skin glow Proper blood flow allows oxygen and nutrients to circulate and nourish skin cells. “Sweat will help the skin look moisturized and ‘dewy,’ which may be seen as improving its appearance,” says Dr. Ganz.

There is no scientific evidence to suggest that you can sweat out a cold and, in fact, it may even prolong your illness. Here’s what you need to know about why sweating won’t help once you’re sick and how you can prevent illness in the future.

Body odor is caused by bacteria breaking down sweat and is largely linked to the apocrine glands. Most body odor comes from these. These glands are found in the breasts, genital area, eyelids, armpits, and ear. In the breasts, they secrete fat droplets into breast milk.

Less body odor Underarm sweat has a direct link to body odor (BO) since it’s the result of bacteria breaking sweat down. When you remove hair under the armpits, it reduces trapped odor. A 2016 study involving men found that removing armpit hair by shaving significantly reduced axillary odor for the following 24 hours.

Sweat can smell like vinegar because of diseases such as diabetes, trichomycosis, and kidney disease, or because of hormone changes, certain foods, or skin infections.

Trimethylaminuria is a rare disorder in which the body’s metabolic processes fail to alter the chemical trimethylamine. Trimethylamine is notable for its unpleasant smell.

The worst smell in the world? It’s dead turtles. Even just thinking about a hot, decaying, dead turtle makes me gag. See, Steen works with reptiles, which stink even when they’re alive.

Scientists have found that dozens of illnesses have a particular smell: Diabetes can make your urine smell like rotten apples, and typhoid turns body odor into the smell of baked bread. Worse, yellow fever apparently makes your skin smell like a butcher’s shop, if you can imagine that.
