What else can I help you with?
Give two differences between evaporation and boiling?
Evaporation takes place at all temperatures but boiling at one particular temperature When saturated vapour pressure becomes equal to the atmospheric pressure boiling takes place but evaporation is not so
How does evaporation cool humans?
Evaporation cools humans by extracting heat from the body when sweat evaporates on the skin. As the sweat evaporates, it takes away the heat from the skin, helping to lower the body's temperature and regulate it in hot conditions. This cooling effect helps prevent overheating and helps maintain a stable body temperature.
What is the relationship between evaporation and the cooling effect it causes in the liquid left behind?
Evaporation is the process in which a liquid turns into a gas. When evaporation occurs, it takes energy from the surrounding liquid, causing it to cool down. This cooling effect happens because the faster-moving molecules escape as gas, leaving behind slower-moving molecules that have lower energy and therefore lower temperature.
Does evaporation take place when drying clothes on line?
Yes, evaporation takes place when drying clothes on a line. The heat from the sun causes the water in the clothes to evaporate into the air, resulting in the clothes drying.
How does prespiring make you feel cooler?
Perspiring helps cool the body by releasing heat through the evaporation of sweat on the skin. As sweat evaporates, it takes heat with it, which helps lower your body temperature and can make you feel cooler.
This takes place when a substance changes from a liquid to a gas at a temperature below its boiling point?
This phenomenon is called evaporation.
When vaporization takes place on the surface of a liquid is called?
If vaporization takes place at the surface of a liquid, it is called evaporation. but when evaporation occurs throughout the substance it is called boiling.
Why the water in shimla evaporates faster?
If the altitude increases the temperature and pressure decreases so the evaporation takes place faster
Why does cooling occur when evaporation takes place?
I think in general,heat is transfer from system to surrounding ,and naturally temperature decrease and it cooled
Can evaporation takes place without heating?
no
How do you find out the effect of evaporation on skin?
Evaporation causes cooling . The skin cools when evaporation takes place.
When your body sweats which process is at work too cool your body off?
The process of evaporation helps cool your body when it sweats. As sweat evaporates from your skin, it takes heat with it, helping to lower your body temperature.
How long does is take for salt water to evaporate?
it takes about 2 weeks
Give two differences between evaporation and boiling?
Evaporation takes place at all temperatures but boiling at one particular temperature When saturated vapour pressure becomes equal to the atmospheric pressure boiling takes place but evaporation is not so
What is formed when evaporation takes place?
its called consintration
How evaporation takes place in tea?
light touches it.
When vaporization takes place of surfaces of a liquid is called?
If vaporization takes place at the surface of a liquid, it is called evaporation. but when evaporation occurs throughout the substance it is called boiling.
