Why does a glass filled with a cold beverage seem to sweat quizlet?
Why does a glass filled with a cold beverage seem to "sweat"? The cold glass cools adjacent air to saturation, which is followed by condensation of water vapor.
Why do drink glasses sweat?
What causes condensation on drinking glasses? Condensation happens when the cool glass is exposed to warm or hot air. The heat from the air transfers to the glass, cooling the air around the cup. Once the temperature is low enough, the liquid will begin to form on the glass.
Why does adding ice to a drink cause condensation?
When the hot air comes in contact with the cold glass, heat is transferred from the hot air to the cold glass. The loss of heat in the surrounding air causes the water vapor by the glass to lose energy. Once energy is lost, the water vapor condenses into liquid on the glass.
Is sweat a condensation or evaporation?
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.
Why are the latent heat of fusion in the latent heat of vaporization said to be hidden?
Heat is absorbed or released, but a temperature change does not take place, so they are "hidden."
Why does a piece of metal feel colder than a piece of wood at the same temperature quizlet?
that metal conducts heat better than wood, meaning you will experience the heat exchange as being more rapid when in contact with the metal than with the wood, giving the impression of the metallic block being hotter (colder) than the wooden one.

Why do cold water bottles sweat?
A cold water bottle appears to sweat because it's a cooling source for the water vapour in the layer of air that surrounds the bottle. Air that is relatively warm can hold more water vapour than cooler air.
How do you make condensation on glass?
Create the condensation If your ambient temperature is warm enough, you will get condensation happening within a minute or so. If it needs a little help, blow over the area with a straw or hold warm hands close, but not against the glass. Placing your glass in the sunshine will also make it happen much faster.
Why do we see water droplets outside of a cold glass?
The vapour loses its energy to the cold water and gets converted to water droplets which we see on the outer surface of the glass. This process is known as Condensation.
Do black people sweat more?
Volume of body sweat increased in both races with rate of walking; volume of hand sweat increased more in Whites than in Blacks. The Mann-Whitney test revealed that volumes of hand sweat were significantly greater for Whites than for Blacks.
Is sweat made of urine?
Sweat Contains a Dash of Pee Although sweat is 99% water, it does contain a dash of pee — the remaining 1% is made up of a combination of ammonia, lactic acid, vitamin C, uric acid, and urea, the main component of urine.
What is the best explanation of latent heat?
latent heat, energy absorbed or released by a substance during a change in its physical state (phase) that occurs without changing its temperature.
Why is latent heat called the Hidden heat explain through an example?
The latent heat is called hidden heat because it does not reflect as temperature changes. Latent heat remains hidden during the change of state. The latent heat is used to loosen the bonding between the molecules and atoms during phase change.
Why does a piece of metal at room temperature feel cold but not a piece of paper?
A: In general, metals feel colder or hotter to the touch than other materials at the same temperature because they're good thermal conductors. This means they easily transfer heat to colder objects or absorb heat from warmer objects.
Why does a piece of metal generally feel cooler to the touch than a piece of wood quizlet?
Why does a piece of room-temperature metal feel cooler to the touch than paper,wood,or,cloth? The metal surface has a better ability to transfer heat from your fingers than the other materials, thus you sense that heat transmission as feeling cooler than the others.
How do you stop condensation on refrigerator glass?
By adjusting your room temperature to be slightly cooler you decrease the dew point as the air becomes cooler and drier. Another option is to install a dehumidifier to control air moisture. With less water circulating to cause over saturation, condensation is less likely to form.
How do you get rid of condensation in a bottle?
The Simple Trick to Wash and Dry Bottles
- FROTH UP. Working over a sink, fill the vessel with 2 inches of white vinegar. …
- DO THE TWIST. To absorb moisture (and prevent residue), tightly roll a paper towel and insert it three-fourths of the way into the bottle; the paper towel will absorb the moisture.

Can a glass sweat?
That “sweat” is condensation. In short the air on each side of the glass is two different temperatures. The warmer air cools as it makes contact with the glass causing the moisture within the warmer air to change from a gas to a liquid and thus you have condensation.
Is condensation in a water bottle bad?
Is this harmful?"– Pat L., Westminster, Md. A: What you are seeing inside the bottle is condensation, or the formation of liquid drops of water from water vapor. Condensation is not harmful; rather, it's what you can't see that may be detrimental to your health.

Why does condensation happen?
Condensation is a change in the state of water from a gas or vapor form into liquid form. It generally happens when vapor in warm air encounters a cool surface. But condensation doesn't need a solid surface to take place, as it can occur when a warm pocket of water vapor encounters colder gasses.
What is condensation process?
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 race has the strongest body odor?
Although there is some controversy on the subject of "racial" variation in body odor, it is determined that African blacks probably produce the greatest amount of apocrine sweat, which is the known substrate for axillary odor.
Do you sweat more as you get older?
Except for women during the menopausal transition, there's no "normal" increase in sweating with age, Glaser says. If you think you're sweating more as you get older, don't just chalk it up to additional birthdays, she says.
Why do my armpits smell like cat pee?
Trimethylaminuria is a disorder in which the body is unable to break down trimethylamine, a chemical compound that has a pungent odor. Trimethylamine has been described as smelling like rotting fish, rotting eggs, garbage, or urine.
Why does my sweat smell sweet?
Here's why: "When glucose levels are too high, and there's not enough insulin to decrease the blood glucose values, this leads to the formation of ketones (a kind of chemical produced by your liver when it breaks down fats) which have a sweet smell," she explains.
How is thermal energy transferred by the process of convection?
Thermal energy is transferred from hot places to cold places by convection. Convection occurs when warmer areas of a liquid or gas rise to cooler areas in the liquid or gas. Cooler liquid or gas then takes the place of the warmer areas which have risen higher. This results in a continous circulation pattern.
Does ice have latent heat?
ice has a very high latent heat of fusion.
What is latent heat of condensation?
Latent heat of condensation is energy released when water vapor condenses to form liquid droplets. The latent heat of condensation is defined as the heat released when one mole of the substance condenses.
