Because alcohol has a much lower boiling point so more exaporates quicker and makes the remaining alochol cold as it consumes latent heat to evaporate.
To help cool the child down. The evaporating alcohol would help with the cooling. To evaporate the alcohol needs some energy and it would take heat from the child's skin thus helping with the cooling. The water would remove heat from the skin by evaporation and conduction.
You can collect the water vapor by condensing it back into liquid form. One way to do this is by allowing the water vapor to cool and then collecting the condensed water droplets. This process is known as condensation.
To cool water quickly, you can place it in the refrigerator or add ice cubes to it. Stirring the water can also help it cool faster by distributing the cold temperature more evenly.
Ice cubes cool lemonade faster than ice water because they have a larger surface area for heat transfer. When ice cubes are added to lemonade, they melt and absorb heat quickly, cooling the drink faster.
No, milk does not cool faster than water. The rate at which a liquid cools primarily depends on its thermal conductivity, density, and specific heat capacity. Water has a higher specific heat capacity than milk, meaning it can absorb and retain more heat, which can make it cool slower than milk.
The alcohol is evaporating, sucking some warmth from your hand as it does, making it feel cool.
sand cools of faster because the sand is less dense and it depends on witch sand beach sand will cool of faster because it is mostly water under it so it will cool of faster
who cares about water
because you feel the water evaporating on your scin and that cools it
That depends on what temperature the pure water is at. Pure water in general does cool faster, however.
beacause its solid
Mpemba effect ,water evaporates faster so it has less water so it freezes faster
No It's warm water the ? was what cools faster cool water is already cool so warm water will cool faster. Plus cool water gets warm Also back in the sixties a experiment was done Hot water froze faster than cold water by a minute . ( I remember this from the Weekly Reader report. lol lol ) I also believe it's meant to suggest when the water is at room temptureroom temperature.
Water will cool faster in the freezer for 1 hour compared to the fridge for half an hour. The lower temperature in the freezer will cause the water to cool more rapidly due to the faster heat transfer rate.
Yes ,the higher the temperature gradient between the hot water and room temperature, the faster it cools. However, that does not mean that hot water will freeze faster than cold water (a common urban legend). If you have water at 50°C in a room at 20°C, it will cool from 50° to 40° faster than it will cool from 40° to 30°.
You would cool a bucket by putting ice into the water.
Yes, water under pressure can cool faster because the increased pressure can lower the boiling point of water, leading to faster evaporation and cooling. Additionally, the higher pressure can enhance heat transfer rates, facilitating faster cooling.
