How Does Salt Water Affected By Cold Water?

In this gummy bear lab, the goal was to see the movement of water in cells depending on the concentration of solutes in the environment. The control group was the type of water used. The research question for this experiment was, how does concentration of solute in the environment affect water movement in cells? The hypothesis thought of for this question was that the salt water would enlarge the gummy bear the most. The distilled water would not enlarge the gummy bear as much as the salt water.

3. The experimental approach to test this hypothesis would be to have two separate bodies of water, one with a set ppm of dissolved oxygen and another with an increasing amount of dissolved oxygen.

Because of this, many possible sources of error in the experiment have to do with water temperature changing. One possible source of error was that the water surrounding the Daphnia magna was constantly returning to room temperature. Once the 30° C water was taken off the hot plate and put in the dish, it was always cooling down to reach room temperature, 21° C, by losing heat to the air. So that the heart rate found during the three different trials may have been at varying temperatures, some cooler than 30° C. Once the 10° C water was put in the dish, it was always warming up to reach room temperature, by gaining heat from the air. This may have caused the heart rate that was found during the three different trials to have been at varying temperatures, some warmer than 10°

In experiment two, “Hand-soaking,” I took the remainder of the salt water solution, which was approximately one cup and placed it into a cereal bowl. Into a second cereal bowl, I placed one cup of tap water solution. I placed one of my hands into the salt water solution and the other hand into the tap water solution. I let my hands soak in each of the solutions for 30 minutes and then observed the

Many people wonder, what big differences are between salt water and fresh water? Is it just water with salt versus water without salt? Those are some common questions people have. Most people ask about the differences, but they forget about the similarities of salt water and fresh water, as well. Did you know that Salt water and fresh water have very different plant and animal life? There are also a few complex fish that can live in both salt water and fresh water. Salt water and fresh water actually have some similarities along with many differences besides salt.

Although we all know ice can create hazardous conditions on your property, we also don't want to create more serious problems by applying the wrong ice melting product. Unfortunately, the use of salt on concrete surfaces has been a major concern for property owners. So how does salt damage concrete surfaces, and what are some of the best alternatives to protecting your pavement?

The purpose of our experiment is to see how salty it is for an egg to float. When salt is added to water, the mass of the water increases, and the water becomes denser. Objects will float better on a denser surface, they float better on salt water than they do fresh water. When you add table salt to water the salt dissolves and the water becomes denser, the volume increases by a small factor but the mass increases by a large factor. The salt is denser than water to begin with, because the salt has more mass than oxygen and hydrogen in the water molecules.

Would you expect endangered species to be more frequently generalists or specialists? Explain your answer.

Through-out the world, there are certain species of plants and animals that can only survive in salt water, while there are other species that can only survive in fresh water. In nature, these species will not naturally nor willingly move out of their habitat and into the other, because it will severely harm them or in most cases, kill them. It requires an outside variable to force these species out of their respective favorable environment and into the other. In the movie “Beasts of the Southern Wild,” an outside variable took place, causing unfavorable living conditions for the plants and animals that called Bathtub their home. This outside variable was the hurricane that passed through Bathtub, which caused the species in bathtub to begin

Rahmstorf (2003) defined thermohaline circulation as deep ocean currents which are carried by density and the gradient of temperature. Rahmstorf (2003) defines salinity as the measure of dissolved salt in water salt. Rahmstorf further explained thermohaline circulation is the direct and largest circulation of water on planet earth occurs, as a result of changes in temperature as well as salinity ( thermo= heat and haline =salt). Similarly Ganachaud and Wunsch (2000) concurs that thermohaline can also be referred to as thermohaline conveyor belt. These currents are formed by differences in water mass density, that are caused by variations both in salinity and temperature, these different currents move water masses through the

In conclusion, my data supports my hypothesis. My hypothesis was that if I pour ice with salt, then the ice amount of ice will be more because salt has more molecules than sugar does. In this experiment I noticed that the first one to melt first was salt. I also noticed that the last one too melt was the control group.

On the countries where snow is abundant or have winter seasons they use salt to melt the snow or ice on the roads, and other areas. When making ice

The purpose of this experiment was to find the amount and percent of water in a hydrated salt. Hydrated salt contains water molecules chemically bound to it while anhydrous salt is a substance that fire can readily remove the water molecules. Using the gravimetric analysis method, the sample salt was measured, heated, and was measured again after cooled down to room temperature; this procedure allowed the weight of water lost in the salt to be obtained. After two trials, the water in the salt was determined to have an average percent water of -35.04%. The null hypothesis, the heat will not affect the amount of water lost, was rejected ,however, the alternative hypothesis, the heat will allow for there to be water lost, was not supported.

Also, to determine if the truck can safely be removed from the lake without the airbags exploding in case the information was needed

Introduction The intent of this experiment is to see if the density of fresh water and salt water effects whether or not a sweet potato will float in it. Based on my research, I know that a white potato will sink in fresh water and that a sweet potato will float in fresh water. I also know that a sweet potato will float in any liquid that is denser than fresh water, like salt water. Based on my research I formed a hypothesis.
