Latent cooling is the process of removing heat from the air without changing its temperature by converting moisture into liquid water. This occurs during the condensation of water vapor in the air, as seen when water droplets form on a cold surface like an air conditioning coil.

Which property of water accounts for the cooling effect of perspiration?
The property of water that accounts for the cooling effect of perspiration is its high specific heat capacity. This means that water can absorb a lot of heat energy before its temperature increases significantly. When sweat evaporates from the skin, it takes away heat energy from the body, leading to a cooling effect.
What requires more energy the latent heat vaporisation of water or the latent fusion of ice?
The latent heat of vaporisation of water requires more energy. This is because on melting, the intermolecular bonds in water are only weakened whereas on boiling, the bonds are completely broken, which requires a larger amount of energy.
How many Btus must be removed from 1lb of water at 200F for it end up as ice at 30F?
To convert 1 lb of water at 200°F to ice at 30°F, you need to remove 233 BTUs. This involves cooling the water from 200°F to 32°F (latent heat of fusion) and then further cooling the ice from 32°F to 30°F.
What is the latent of vaporization?
The latent heat of vaporization is what is commonly referred to as boiling. This is the amount of energy require to change from a state of liquid to vapor.
Why is rubbing alcohol cooler on your skin than water?
Rubbing alcohol has a lower specific heat capacity than water, meaning it absorbs heat from your skin more quickly. This rapid heat transfer gives the sensation of cooling. Additionally, evaporation of alcohol from the skin contributes to a cooling effect due to latent heat of vaporization.
The wet adiabatic rate of cooling is less than the dry rate because?
the wet adiabatic rate of cooling involves condensation of water vapor, releasing latent heat which partially offsets the cooling from expansion. This latent heat addition makes the wet rate slower than the dry rate, where no condensation occurs.
The wet adiabatic rate of cooling is less than dry rate because?
of the release of latent heat
What does the body depend upon when cooling itself in a hot environment?
The latent heat of evaporation of water - the evaporation of sweat.
The wet adiabatic rate of cooling is less than the dry rate?
of the release of latent heat
Why does sweating cause cooling?
Sweating has a cooling effect due to the latent heateffect of the evaporation of water. Although sweat is not completely composed of water, water from sweat evaportates at the skin's surface. The latent heat effect means that energy in the form of heat is released from the body when the water from sweat evaporates into the atmosphere on one's body.

What is called the release of latent heat along from water molecules on a wet surface?
The release of latent heat from water molecules occurs during the process of evaporation from a wet surface. This latent heat is absorbed by the water molecules to break intermolecular bonds, allowing them to transition from liquid to vapor state.
What late heat mean in HVAC?
All pure substances in nature are able to change their state. Solids can become liquids (ice to water) and liquids can become gases (water to vapor) but changes such as these require the addition or removal of heat. The heat that causes these changes is called latent heat. Latent heat however, does not affect the temperature of a substance - for example, water remains at 100°C while boiling. The heat added to keep the water boiling is latent heat. Heat that causes a change of state with no change in temperature is called latent heat. Appreciating this difference is fundamental to understanding why refrigerant is used in cooling systems. It also explains why the terms 'total capacity' (sensible & latent heat) and 'sensible capacity' are used to define a unit's cooling capacity. During the cooling cycling, condensation forms within the unit due to the removal of latent heat from the air. Sensible capacity is the capacity required to lower the temperature and latent capacity is the capacity to remove the moisture from the air.
What does 2.5 ton ac mean?
Cooling capacity of 30,000 btu per hour. That is the nominal total of both sensible and latent heat.
Why in ice cube at 0 degree Celsius is much effective in cooling a drink that the same mass of water at 0 degree Celsius what is the formula?
Latent heat of the ice, liquid water has no latent heat reserves. Perhaps at freezing we should call it "latent cold" but thermodynamics has always referred to it as latent heat whether at boiling or freezing. +++ It is latent heat because the water (liquid or ice) at freezing-point (0ºC) still contains heat energy as its temperature is at about 217ºK.
A system that cools the air by spraying water into a tower is called?
The system you are referring to is known as an evaporative cooling tower. It works by using the latent heat of vaporization to cool the air as water is sprayed into the tower and evaporates, absorbing heat in the process.
How does latent heat impact the cooling or heating of air?
Latent heat is the energy absorbed or released during a phase change, such as when water evaporates or condenses. In the atmosphere, when air cools and reaches its dew point, water vapor condenses, releasing latent heat and warming the surrounding air. Conversely, when air warms and evaporates water, it absorbs latent heat and cools the surrounding air. This process affects the temperature and stability of the air mass.
