atmospheric pressure is what we call “vapor pressure.” Of course, as the molecules (once liquid but having evaporated are now in gas phase) bounce around the container, some will inevitably shoot back into the liquid. Others will condense. Initially, there are not enough gas molecules to reform liquid, so the rate of evaporation continues fairly unhindered. Eventually, however, enough gas molecules will have accumulated so that many molecules will be forced back into the liquid, and this rate of condensation

Do you think that all liquids evaporate at the same rate? Without any research an average person would think that water and oil would evaporate at the same rate since they are both liquids. Through research, science shows that due to their density oil will take longer to evaporate since it has more mass. Does the amount of density in the liquids make them all evaporate at the same rate? All liquids do not evaporate at the same rate because denser liquids take longer to evaporate. Why does water evaporate

molecules. -A statement that under the same conditions of temperature and pressure equal volumes of molecules. This empirical relation can be derived from the kinetic theory of gases under the assumption of a perfect gas. The law is approximately valid for real gases at sufficient low pressure and high

Living in a winter wonderland can be enjoyable with lots of snow for skiing and freezing weather and ice for skating. Cold climates can have their drawbacks as well. For instance, if you live in areas that have freezing temperatures, then you might be familiar with what damage frozen water pipes in your home can do. A sudden or unexpected drop in temperature, especially at night, may catch you off guard if you have not taken the proper precautions to winterize your home's water pipes. Then your winter

pressure loss. Since there is a small amount of dissolved nitrogen in the water, some of the nitrogen's partial pressure loss is "corrected" by oxygen. Effectively, the plastron trades some of nitrogen for oxygen, thus keeping a constant volume of gas that slowly becomes enhanced with

in this experiment, a heat source will be used to evaporate different liquids. The results will show if certain liquids do, in fact, evaporate faster or slower than others depending on their ingredients. How do liquids change from a liquid to a gas phase? A liquid is a primary state of matter that has no specific shape. According to chemwiki.ucdavis.edu, "Liquids are more dense and less compressible than gasses. Liquids have a definite volume, independent of the size and shape of their container

Purpose: In this experiment, I performed a Diels-alder reaction by refluxing anthracene with maleic anhydride in xylenes to form a bridged bicyclic product at high temperature. The reflux technique involves continuous boiling of a solution to the temperature of reaction solvent where evaporating solvent is condensed back into the original reaction flask. The product was collected by recrystallization technique and characterized using melting point. A white powderish anthracene and white somewhat-crystallized

Introduction: The experiment's goal was to determine the freezing point of a pure solvent and the freezing point depressions of two solutions. The freezing point and the freezing point depressions were determined by graphing the temperature of the pure solvent and two solutions as they cooled and observing when crystals first formed. Experimental Tf for benzophenone and percent error: The experimental freezing point of benzophenone was 45.06oC. With an accepted value of 47.8oC, the percent error

25ml of an unknown alcohol will be purified using fractional distillation, the unknown alcohol will begin to boil when heated, until it reaches its boiling point, distillate will be collected. The temperature of this alcohol will be recorded and will be analyzed to the literature boiling point values of the substances listed below. the unknown alcohol will slowly begin to boil and reflux will begin to form, the temperature will slowly increase as the phase changes from liquid into vapor with additional

"Harlan, honey, what are you doing?"Asked Harlan Sander's wife. He was fishing on the bank of a pond, his face was down, and wrinkles of worry were popping up all over his face. The corners of his mouth twitched. His eyes were tired and looked as if he had not slept in a long time. "I am fishing, trying to catch us dinner, after all, we do have to close our shop" "Honey, its ok we have enough money to last us a while, we will not be sleeping in the streets anytime soon!" "That money cannot
