The Evaporation Race

Ice starts as water that has a temperature of any degree above thirty-two degrees Fahrenheit. Before water technically becomes water, which is the name of the liquid state, it starts as a gas called water vapor. After water vapor condenses because of a loss of energy, it is then in liquid phase of H2O, called water, which can then be broken down in the smallest unit; atoms.

We’ll measure how long each liquid evaporates at room temperature. So each liquid won't evaporate faster just because of the temperature. Each liquid has a different evaporation rate. Evaporation occurs when a liquid is sitting in a spot for too long. The evaporation rate of a liquid is affected of what type of liquid it is. And the temperature of what the liquid is sitting in. Such as a puddle sitting in 100 Degrees Fahrenheit. The puddle will evaporate faster because it is in a hot environment. Evaporation can also happen when it's cold. However heat makes the liquid evaporate faster.

Early pioneering studies on interactions between liquid water, water vapour, and heat movement were reported by Philip and de Vries (1957), who provided a mathematical description of liquid water and water vapour fluxes in soils driven by both pressure head (isothermal) and soil temperature (thermal) gradients.

The release or agitation of the water would release the co2 causing the water to rise and evaporate.

When something boils it evaporates because the liquid molecules gain enough energy to escape the system and become gas. When this happens we see steam, or water vapor.

Evaporation- when water evaporates in the form of water vapor by the heat of the

2A. Evaporation is related to the properties of matter because it is a liquid and a gas. We know this because there are three states of matter which are soild, liquid and gas since evaporation first starts as a liquid (water). Then it turns into gas (cloud).

The viscosity of water can be affected by temperature, and by pressure and temperature, but not by pressure on its own. As a liquid, it is incompressible and so isn’t affected much by pressure. As the temperature applied to water increases, it starts to become unstable, like when water in a pan begins to boil and it starts to bubble. When water reaches its boiling point, its state changes from a liquid to a gas, and it becomes steam.

Definition of rate of evaporation. How it changes as temperature changes. Therate of evaporationcan be defined as the number of water molecules that change phase from liquid to gas each second. The rate of evaporation is mainly set by the temperature of the liquid water.The higher the temperature of the liquid water, the faster the rate of evaporation. Definition of rate of condensation. How it changes as vapor pressure (a measure the amount of the gas water vapor above the liquid surface) changes. Therate of condensationcan be defined as the number of water vapor molecules that change phase from gas to liquid each second. The rate of condensation depends mainly on the vapor pressure in the space above the liquid surface. Thus, the higher the concentration of water vapor molecules above the liquid surface, the faster the rate of condensation. What is meant by saturation Why will a closed system like this always move toward saturation with respect to water vapor You may take saturation to mean the capacity or maximum amount of water vapor that will can exist in the air at a particular temperature. It is important to understand that saturation vapor pressure (or the maximum amount of water vapor that can be in the air) increases exponentially as temperature

Evaporation (transpiration) Heat from the sun warms water from rivers, lakes, and the ocean to turn into vapor or steam; leaving the reservoir and moving upwards into the atmosphere. (Plants transpire, or lose water from their leaves).

In this experiment, we investigate the change in temperature caused by adding a chemical substance into the water and dissolving it. The results recorded in the table below show that our hypothesis is correct.

My hypothesis was proven because water was one of the fastest liquids to evaporate. Both vinegar and water ,after 72 hours, ended at 9g while root beer ended at 11g and saline ended at 10g. At first root beer and saline were evaporating quickest but then slowed down toward the end. Both vinegar and water were slow but near the end evaporated hugley. I believe that the root beer and saline slowed down at the end because of the salt and sugar weighing it down while water is only water and vinegar is made up of mostly water and acetic acid; neither had anything to weigh them down.

The volume is definite if the temperature and pressure are constant. When a solid is heated above its melting point, it becomes liquid, given that the pressure is higher than the triple point of the substance. Intermolecular (or interatomic or interionic) forces are still important, but the molecules have enough energy to move relative to each other and the structure is mobile. This means that the shape of a liquid is not definite but is determined by its container. The volume is usually greater than that of the corresponding solid, the most well known exception being water, H2O. The highest temperature at which a given liquid can exist is its critical temperature.[5]

The hypothesis that water would evaporate the fastest was incorrect. When studying research hydrogen bonding in water makes them bond together thus making it slower to evaporate. The experiment explained that the liquids that didn't have as much hydrogen bonding evaporated faster. To improve this experiment one could test different liquids and put them in different locations. An additional experiment that could be tested would be if temperature affects evaporation rates.

These phases can go from one to another when affected by certain things, which is known as phase changes. To switch from a solid to a liquid, the solid must melt. On the other hand, to switch from a liquid to a solid, freezing must occur. Furthermore, to switch from a liquid to a gas, a process known as evaporation must take place. In contrast, to
