of the Second Law of Thermodynamics, which states that heat naturally flows from hot objects to cold objects until thermal equilibrium is reached. This means that hot things cool down as they transfer heat to their surroundings, while cold things warm up as they absorb heat from their surroundings.
Sitting in a cold bathtub helps cool down your body because the cold water draws heat away from your skin, lowering your body temperature. This process is known as conduction, where heat is transferred from your body to the cold water.
Freon itself if not cold. Freon can be used to cool things by compressing the gas and then letting it expand. When a gas expands, it cools down (for more information about that, look up the Ideal Gas Law). Freon is very effective for this purpose and because it is a gas with a high heat capacity. Any gas can cool thing in the same way, but Freon does it particularly well. Unfortunately it is what is called a CFC, which destroys ozone in the atmosphere.
It isn't really all that much cooler. On cool nights it can be, because ocean breeze carries moisture which feels cold in cool temps.
Ice helps to constrict blood vessels, reducing blood flow to the burn area and limiting inflammation. This can help to alleviate pain and prevent further damage. Cold water can also be effective, but ice provides a more rapid and intense cooling effect.
Cool air is typically dry because cold air has a lower capacity to hold moisture compared to warm air. As cool air cools down, its ability to retain humidity decreases, leading to lower relative humidity levels. This is why cold environments often feel dry.
Hot things get cooler, and cold things get warmer, because they exchange heat with their surroundings. A "cool bag", whatever that is, is apparently designed in such a way as to prevent that (probably it's insulated).

cool clothes and cool shoes and cool things!
because its cool
Alot of things.
Spain is so cool because it is :)
Cotton is a breathable fabric that helps maintain a cool and comfortable temperature by allowing air to circulate. However, it does not have the ability to actively keep things cold like an insulating material would.

The best way to keep something cold is to place it in a cooler that is filled with ice. You can also place things underground to keep them cool or place them in a refrigerator.
because cool drink is cold
yes.. because they are cool
