Quick and dirty answer: Because the liquid that is evaporating must absorb heat in order to do so. It is much like melting ice. The ice melts because is absorbs heat. If there is no heat for it to absorb, it remains ice.

Why does alcohol creates a cooling sensation?
Since alcohol evaporates very quickly, it wicks out heat from your skin. Its exactly what sweat does for your body, but its not a significant cooling sensation like Alcohol, since sweat evaporates slower.
What is the surface cooling that results when a substance evaporates?
surface cooling occours when a substance evaporates after taking sufficient heat from the body itself intended to be cooled, creates a sensation of cooling on the body. But in air conditioning the surface cooling, is one of the method of cooling, having different explanation.
What is the great cooling effect produced by water evaporating, and how does it relate to its high evaporation rate?
The great cooling effect produced by water evaporating is called evaporative cooling. When water evaporates, it absorbs heat from its surroundings, causing a cooling effect. This cooling effect is related to water's high evaporation rate because the faster water evaporates, the more heat it can absorb, leading to a greater cooling effect.
The cooling effect of perspiration as it evaporates from the skin is the result of high of water?
The cooling effect of perspiration is due to the high heat capacity of water. As sweat evaporates from the skin, it absorbs heat energy from the body in order to change from a liquid to a gas, resulting in a cooling effect.
Does the refrigerant in a cooling system evaporate surronding air?
Yes, the refrigerant in a cooling system evaporates by absorbing heat from the surrounding air. As the refrigerant evaporates, it transitions from a liquid to a gas, effectively removing heat from the indoor environment and cooling the air. This process is essential for the functioning of air conditioners and refrigeration systems.
What fluid cools your body when it evaporates?
Sweat is the fluid that cools your body when it evaporates. As sweat evaporates from your skin, it takes away some of the heat from your body, resulting in a cooling effect.
Why do you feel cool when you switch on the fan?
Moisture evaporates, thereby cooling off body heat
Is evaportation a cooling mechanism?
Yes, evaporation is a cooling mechanism. When a liquid evaporates, it absorbs heat from its surroundings to break the bonds between its molecules and transform into a gas. This absorption of heat causes a cooling effect on the surroundings.
What is the Evaporation of sweat cooling the body is an example o?
The evaporation of sweat cooling the body is an example of thermoregulation. When sweat evaporates from the skin, it helps regulate the body's temperature by dissipating heat and cooling the body down.
How does sweat cool the body by removing heat?
Perspiration is moisture on the skin which evaporates. Evaporation sends the atoms of perspiration into the air. It takes energy (heat) to do this, so as the heat leaves the skin, the skin becomes cooler.
How does perspiration help to cool your body?
Perspiration, or sweat, is produced by the sweat glands in the skin in response to an increase in body temperature. When sweat evaporates from the skin's surface, it draws heat away from the body, cooling it down. This process helps the body maintain a stable temperature and prevent overheating.
How does refrigerant absorb heat in a cooling system?
Refrigerant absorbs heat in a cooling system by circulating through the system and changing from a liquid to a gas state. As it evaporates, the refrigerant absorbs heat from the surrounding air or water, cooling the area.
