A fall in the temperature of the liquid known as the cooling effect, accompanies evapouration because as the faster molecules escape through the surface the mean energy of the remaining molecules escules falls. For example, the effect may be noticed when wet clothes are worn and swet evapourates from the skin.
if ya get m' drift?
Liquids need heat energy to evaporate, so it takes the energy from the area around it, causing the area to lose heat.
yes
when liquid evaporate, it turns into a gas. The evaporation process causes cooling on the surface of where the liqiud originated
The latent heat of evaporation.
In order for liquid to evaporate, potential energy should first be acquired to be able to transform to gas. This energy will be stored as heat. Heat will not cause temperature to increase and this is known as latent heat. Boiling of water puts potential energy into it. Once it boils, the water evaporates into the air and also takes heat from the surroundings. This is what causes the cooling effect of evaporation.
When you perspire, the sweat evaporates and gives off this cooling effect. There are many examples to show it too.
yes
a fall in the temperature of the liquids known as the cooling effect ,accompanies evaporation
Cooling does not cause evaporation. Warming does. This is because as the air warms up, there's more space for water vapor in it. Water evaporates and turns into water vapor to fill this space.
Evaporation needs heat energy. During the process of evaporation heat is absorbed by the other body thereby cooling it
mum
evaporation Cooling is a decrease of the temperature of a system or material.
Evaporation causes cooling . The skin cools when evaporation takes place.
sweating
calculation for cooling tower evaporation capacity.
evaporation helps us by cooling us down! :)
Heating a pool will increase the rate of evaporation from that pool.
the cause is, evaporation is escaping of fastest, which are "hottest" one, particles (molecules, atoms), which leaves the cooler ones in liquid, so median temperature dropping towards coolest particles of liquid.
