Evaporationin Our Daily Life

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.

Section 1: Gather the following information from field research while in the Phase 3 lab environment. Notice that each site you visit has a distinctly different surface, which could affect runoff.

The experiment of the lab was to demonstrate knowledge of the concepts of diffusion and osmosis. Diffusion is the movement of substances moving from a high concentration to a low concentration. For this lab the rate of osmosis was measured in concentration. The concentration stayed the same and increased through the experiment. At the beginning of the experiment the sacs were weighed to determine the tonicity of water throughout the experiment. Timing was also a factor each 15, 30, 45 minute interval the sacs were weighed and recorded. Each sac had a different amount of solution in them. The tonicity of the sacs was determined as well by the final weights and the final percent of gain or loss of water in the sacs.

To start off the lab we did simple measurements with two different rulers, both measuring in centimeters but had different amounts of divisions on the second one making its measurements more precise. The first item to measure was a 13 x 100 mm test tube, again using the two different ruler’s metric ruler A and metric ruler B. After recording the measurements with the accurate rounding, we did the same steps to measure the diameter of a watch glass and an evaporating dish.

1. The relationship between rate of diffusion/ osmosis, volume, and surface area can be easily seen and analyzed through the data that was collected from procedure one: Surface Area and Cell Size. Phenolphthalein is a dye-material in this lab that was used to determine whether a substance was an acid or base. This could be told as the phenolphthalein changed into a murky. Muddled and clouded color when mixed with acids. When the chemical aid was mixed in with a base, the color

They are alive poems” (15-16). The plants and animals have evolved and developed to fill specific roles and niches on the earth. People should not just use the plants and animals without regard for their place on the earth; instead, people should study the plants and the animals, learn from them, and in exchange, protect them from misuse, over-use, or destruction. This is important because “all is in motion, is growing, is you” (23), the speaker tells the listener. If the listener cannot learn from the plants and the animals, cannot protect the earth, or cannot relate to her fellow human, the fragile relationship between the environment and humanity is disrupted, and the growing stops. Without the growth, humanity will soon cease to be, because that growth is what makes humanity what it is, it is what provides the catalyst for people to think, to speak, to advance.

Abstract: This experiment introduced the student to lab techniques and measurements. It started with measuring length. An example of this would be the length of a nickel, which is 2cm. The next part of the experiment was measuring temperature. I found that water boils around 95ºC at 6600ft. Ice also has a significant effect on the temperature of water from the tap. Ice dropped the temperature about 15ºC. Volumetric measurements were the basis of the 3rd part of the experiment. It was displayed during this experiment that a pipet holds about 4mL and that there are approximately 27 drops/mL from a short stem pipet. Part 4 introduced the student to measuring

6. It influences how much of the sun’s energy is absorbed and released, thereby affecting temperature. Plants release water vapor and influence regional precipitation patterns.

D. The water and oil acted differently on the reaction surface. Propose a hypothesis that explains the different behavior of

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

Understanding the beauty in nature has always been a struggle of mine. In this world of iPhones, laptops, and television at our fingertips, one can become trapped in the black hole of becoming disconnected with nature. I have always planted a flower garden and watching each color try to outshine the other showed me the purest of joys in life; everyone has a pull inside their natural being to be one with nature. Looking at all the awesome creatures God has made for this Earth made me realize that He wants us to enjoy our time on this physical land while we can.

Osmosis is a form of diffusion that occurs when there is movement of molecules across a cell membrane in liquid. With the lab one will be able to see the size of three gummy bears change due to being soaked in multiple types of water overnight. Each gummy bear's mass and volume are recorded, and then placed in a beaker of tap, sugar, or salt water. The following day all three gummy bears are taken out to be remeasured after to see the effects on it from osmosis happening. In all of the gummy bears, both the mass and volume increase, resulting in the size of the bears to increase. The bear with the most percentage of change in mass and volume is the one in tap water. The least amount of change in mass and volume occurs in the cup with salt

I started to wonder how fast does dry ice evaporate and does a different liquid make it evaporate faster or

An error that could have occurred during this experiment would be the failure to heat all of the water particles in the air off the

A photograph of Earth reveals a great deal, but it does not convey the complexity of our environment. Our environment (a term that comes from the French environner, “to surround”) is more than water, land, and air; it is the sum total of our surroundings. It includes all of the biotic factors, or living things, with which we interact. It also includes the abiotic factors, or nonliving things, with which we interact. Our environment includes the continents, oceans, clouds, and ice caps you can see in the photo of Earth from space, as well as the animals, plants, forests, and farms that comprise the landscapes around us. In a more inclusive sense, it also encompasses our built
