evaporative cooling
Latent heat
When water vapor condenses into liquid water, latent heat is released. Similarly, when liquid water freezes into ice, latent heat is also released. These changes of state involve the release of latent heat because energy is being released as the water molecules transition to a lower energy state.
A latent print shows up better on a smooth surface because there are fewer irregularities or imperfections for the fingerprint residue to get trapped in. This allows for clearer ridges and patterns to be visible compared to a rough or textured surface where the residue may be dispersed or obscured.
The rising air cools at a rate known as the dry adiabatic lapse rate, which is around 10°C per 1000 meters of ascent. This rate does not account for the release of latent heat, which slows down the cooling process as moisture condenses.
The energy required to make a phase change, such as melting or boiling, is called the latent heat of fusion or vaporization. It is the energy needed to change the state of a substance without changing its temperature. This energy is used to break the intermolecular forces holding the molecules together in a particular arrangement.
An increase in surface area will typically increase the rate of evaporation. This is because more surface area means more of the liquid is exposed to the surrounding air, allowing for more molecules to escape as vapor. Additionally, increased surface area can lead to a thinner layer of liquid, reducing the distance vapor molecules need to travel to escape.
The energy absorbed and stored in vaporous molecules is referred to as latent heat. This represents the energy required to change the state of a substance without a change in temperature, such as during the process of evaporation or condensation.
Latent heat
Yes, that's right.What you are referring to is called the enthalpy of fusion or the latent heat of fusion.
When water vapor condenses into liquid water, latent heat is released. Similarly, when liquid water freezes into ice, latent heat is also released. These changes of state involve the release of latent heat because energy is being released as the water molecules transition to a lower energy state.
pChanges in bonding arrangements between atoms and molecules result in absorption or release of heat (called latent heat). For example when water freezes, some heat is extracted to the environment, and the temperature does not fall until all is frozen. After that further removal of heat causes the temperature to fall below freezing point.

couldn't you but paint on a finger and press into it???
Water and other liquids absorb heat energy from their surroundings when they evaporate. Since the high-energy molecules leave the liquid's surface, the remaining liquid molecules have less average energy , That makes evaporation a cooling process.
