Evaporation Lab Essay

Evaporation is when a liquid turns in to gas, there argon a few ways it does this. The fastest moving molecules at the surface of the liquid have enough power to desecrate the their bonds with other molecules. Since at higher temperatures the molecules have more kinetic energy, more of them are likely to escape, and so dehydration occurs more quickly at higher temperatures. So desiccation occurs because systems hear equilibrium which means there is a low assiduousness of molecules in the air, and a high concentration in the liquid. In a automobile there is evaporation going on to get the machine cooler and making the car move.

there are factors that effect the rate of evaporation for a substance, by changing these factors, the rate of evaporation croupe be change magnitude or slowed down depending how u alter them. The factors are the temperature, wind, expose surface area, and the humidity. If you increase any of these factors the substance will vaporize quicker.

When the liquid molecules are on a surface, there is mucilaginous and adhesive forces acting between the liquid and the surface. With a viscid fore the liquid does not postulate to be on the surface and trys to bead up to serve like little liquid droplets on the surface, when the molecules are adhesive the liquid trys to cover as more surface as possible.



When the molecules are being adhesive the evaporation is greater because of the larger surface area, when the molecules are cohesive the evaporation is slower because of the minimal surface area.

The molar mass can greatly effect the rate of evaporation in a substance. As the atmospheric pressure increases the boiling point increases. So as the molar mass increases this means it takes more energy to evaporate the liquid. So if the molar mass is lower, you will accept less energy to evaporate the liquid.

As a car runs theres is coolant running through the engine stressful to keep the engine from getting too hot. There is also fuel and oil being spit around inside...If you want to get a full essay, order it on our website: Ordercustompaper.com
