heat of vaporization for isopropyl alc is 159 cal/grams
Ch3-c(ch3)-o-c=och2-ch3
Clean the CPU and the base of the heat sink with isopropyl alcohol before applying the thermal compound.
Rubbing Alcohol will evaporate at about 37 COr about 98.6 FRubbing alcohol (isopropyl alcohol) will begin to evaporate at temperatures above -175 degrees F. It is a very volatile substance, It evaporates faster at warmer temperatures.
it is the simple principle of evaporation. The same effect can be acheived with any liquid that can evaporate at or around body temperature. Alcohol has a low evaporation point, when you apply it to your skin it draws heat energy from your skin and evaporates off, this process has a cooling effect because it is drawing heat energy from your body.
Heat, or energy, is needed for evaporation to occur. Energy breaks bonds holding water molecules together, making evaporation possible.
In condensation heat is removed In evaporation heat is added
isopropyl alcohol
the boiling point of isopropyl alcohol is 82.5 degrees celsius or 355.5 K
heat energy
No. Its evaporation uses heat energy and causes it to cool.
It is called the Opposite of Condensation - that is Evaporation.
Heat is absorbed by the molecules leaving the place the evaporation is occuring. That is why, after putting aftershave or cologne, you feel cold. The alcohol in the aftershave/cologne has evaporated and taken the heat from your face with it.
Before rubbing alcohol absorbs, it is a liquid. While it absorbs (heat), the phase change occurring is evaporation. As the alcohol takes in heat, it turns into a gas.
It is important to heat treat in vacuum as otherwise lots of oxides form; after heat treat in vacuum oxides are removed, if part small enough, by use of an abrasive grit pad, such as Scothbrite A, and cleaned with acetone followed by isopropyl alcohol. If not protected, however, oxides will continue to form in air

Unplug the device, and sterilize with isopropyl alcohol applied to a washcloth, then allow the alcohol to evaporate. Even turning on the device should kill them due to the heat, but it's a good idea to use alcohol first.
