Evaporation

Leanna Lim Mrs. Stout P1 1/20/16 The Evaporation Race When it rains, puddles of water are often left behind, but it starts to disappear after just a few hours. What is happening? This is called evaporation. Evaporation is a very common natural process that occurs all around the world, where a liquid changes from a liquid state to a gaseous state. Evaporation occurs when enough heat energy is absorbed by the molecules in a liquid state to the point where it starts to vaporize. Do other liquids react

another, such as vaporization, this is the process by which a liquid or in some cases a solid that can change into a gas. Evaporation is a similar form of vaporization. However, evaporation is defined as the process by which particles escape from the surface of a non boiling liquid and enter the gas state. Some lab experiments can be conducted to actually see the effects of evaporation. Like the liquid bromine lab where you add a small amount of liquid bromine into a bottle, and within a few minutes,

kind of bothering me for a while or a while so i was curious and I asked around and eventually found out that it is evaporation and that this is the cause of my drink running away. It is actually evaporation is taking the liquids up into the sky and creates moisture in the air and clouds. So then I thought like soda and other substances like sugar maybe could weigh it down the evaporation rate of the and evaporate slower than other things. This could also help with other places where water is scarce

Evaporation is the process that changes liquids into gases. When a liquid is heated, it becomes a gas and spreads into the atmosphere, or the surrounding air. Liquids becomes gases by adding thermal energy to them. Thermal energy is the amount of energy any matter has because of the moving particles, molecules and atoms, inside it. The lakes, rivers, and oceans evaporate when the sun comes out and heats them up. The molecules from the bodies of water rise from Earth’s surface into the surrounding

My science fair topic is Evaporation. I chose Evaporation because we talk about evaporation but most of us don't see it often at all. Evaporation is an interesting topic and and a piece of matter people don’t really put their interest in. Evaporation happens the Water cycle. An ocean like the pacific evaporates into the clouds, condensates, and precipitates. It happens over and over again. I bet that people put their drinks out and never cover it before going to sleep and a few hours later, It has

Evaporation is eminently fundamental for the human life. Without evaporation, there would be no crops, no rain, and the human body would overheat. When most people think about evaporation, they usually associate it with the water cycle. All liquids can evaporate at room temperature, including water, orange juice, rubbing alcohol, and nail polish remover, but do they all evaporate at the same rate? Surprisingly, most people do not take into consideration that evaporation also occurs in their own home

Water Affect its Evaporation Rate? Evaporation happens when water molecules turn into gas. Many things can affect how quickly this happens. For example, evaporation occurs faster in warm weather than in cold weather. This is because heat increases the energy of water molecules. The more energy involved, the faster the evaporation rate. Other factors can affect the speed of evaporation too. Anything that slows down water molecules’ movement will slow down the evaporation process. Anything

important to life on Earth, because about 90% of things on Earth need water or use water to live. Humans, Animals, and Plants all need water to live and without it we wouldn’t survive. Evaporation, Condensation, Precipitation, Transpiration, and GroundWater Runoff are the steps in the Water Cycle. Evaporation~ Water changes from a liquid

to proficiently separate a mixture, using filtration and evaporation. In this lab, a homogeneous mixture will be created, along with a heterogeneous mixture.The two mixtures will be mixed together, yet separated. Common substances will be mixed and then separated using two of the techniques already listed; filtration and evaporation. Theory If the salt, sand, and water mixture is separated successfully through filtration and evaporation, then the percent recovery of the salt and sand will be 100%

the Rate of Evaporation? Aim * To find out if changes in temperature, draught and surface area of water open to air affects the rate of evaporation through the water. * To safely check if these variables change the rate of evaporation * To complete all the experiments in the short period given Prediction * I believe that a raise in temperature will speed up the rate of evaporation in the water * I believe that a larger surface area will speed up the rate of evaporation in the water
