Why does evaporation cause cooling? Briefly explain why it is important for the beaker of water to cool slowly and for you to stir the naphthalene liquid as it cools. Why is agar an appropriate medium to use for separating molecules?
Why does warm air rise? Why does water evaporate faster than alcohol? Why is ice the solid form of water? Why can't cold air hold much water vapor? Why is evaporation a cooling process? Why does water cool when it evaporates?
The key to sweat’s cooling power is evaporation. Evaporation is what happens when a liquid becomes a gas. In this case, the sweat from your skin evaporates into the air around you. Sweat needs some of the heat from your body in order to change from a liquid to a gas. That’s calle...

Its use for the generation of electrical energy is particularly wasteful in that up to 60% of the heat is being discarded by heating the cooling water or by evaporation in the cooling towers. A better application of natural gas is residential heating in which nearly full use is made of the...
Monitoring the temperature of the concrete during phase III and IV is a quality control component that is regularly performed. The main reason behind this measurement is to ensure the concrete does not reach temperatures that are too high or too low. This allows proper strength development and im...
