I first went out and bought my materials - light bulbs, four rubber light sockets, nine ounce plastic cups, four 15" by 15" by 15" cardboard boxes, duct tape, and a disposable camera. I then put the boxes together. I measured to the center of the top of the box and placed a dot there. I then poked the light socket through at the dot, making sure that the prong was exactly two and one-half inches above the box. I taped the light to the box in that spot. I then measured to the center of the bottom

Evaporation Science Fair Research Paper By: Suzie Science Ms. Willis’ Class December 16, 2008 Background Information Liquids are all around us. Every day we drink and eat items that contain liquids, we use liquids to clean ourselves and our belongings and liquids can even be found in the places that we would not expect, like televisions. When someone watches liquid over time, an interesting thing begins to happen. The liquid will slowly start to disappear. The formal term for the liquid disappearing

the ocean but when thinking that it will be the same but it wasn’t he was being transported to the air with other water droplets from oceans and plants around them, they all were turning in gas to form a cloud in the sky. That’s when evaporation comes to play evaporation is when a gas state (vapor) the sun’s light gives energy to the water, causing it to change from a liquid to a gas. Then which also helps is transpiration when another gas state. The process where plants release water vapor into the

Background Research In my experiment I will be looking to see how the pH level effects the evaporation rate of water. After looking at previous studies on both water evaporation and the effects pH can have I created my hypothesis that the lower that the pH level of the water is the faster the rate of evaporation in the water will be. Evaporation is when liquid is vaporized from the surface of the liquid into the form of gas. It happens when atoms escape from the liquid and become vapor. If the relative

at the same rate? Evaporation is when a liquid turns into a gas. The molecules move and vibrate so fast that they go into the atmosphere as molecules of water vapor. Evaporation is very crucial in the water cycle. The hotness from the sun powers the evaporation procedure. Water starts to evaporate at about 32 degrees Fahrenheit but it occurs gradually. As the temperature rises, the evaporation starts happening quicker. So the warmer it is the faster evaporation happens. Evaporation rates also depend

SC4730/1125 ENVIRONMENTAL SCIENCE SHIVAJI PRASAD UNIT1 WATER CYCLE Evaporation is the process by which water changes from a liquid to a gas or vapor. Evaporation is the primary pathway that water moves from the liquid state back into the water cycle as atmospheric water vapor. Studies have shown that the oceans, seas, lakes, and rivers provide nearly 90 percent of the moisture in the atmosphere via evaporation, with the remaining 10 percent being contributed by plant transpiration. A very

OBJECTIVES The objectives of this experiment are as follow: • To study the rate of evaporation of water, acetone and diethyl ether. • To determine the intermolecular forces of the liquids. INTRODUCTION Evaporation is the process whereby atoms or molecules in a liquid state gain sufficient energy to enter the gaseous state. The thermal motion of a molecule must be sufficient to overcome the surface tension of the liquid in order for it to evaporate, that is

which water is continuously cycled. Evaporation, transpiration, condensation, precipitation, and runoff are the five major parts of this cycle. Evaporation is the process where water changes from a liquid to a gas or vapor. Evaporation is the primary part in the water cycle that moves from the liquid state back into the cycle as a gas. Studies have shown that 90% of the moisture in the atmosphere is from oceans, seas, lakes, and rivers which is from evaporation. The other 10% of moisture is from plants
