loss or obtains. All the tubes contained different amount of sucrose concentrations. The higher molarity concentrations increased the movement of water to balance out the inside of the tube and the beaker. The greater amount of concentration gradient‚ in each tube‚ increased the rate of osmosis. This rate of osmosis is due to the net movement of water from an area of low concentration to an area of high concentration. Because the tubes had different concentrations‚ certain tubes gained more

What Beverages Stain Your Teeth The Most? In my experiment I will be testing drinks‚ to find out which drink will stain your teeth the most. The drinks I will be using are coffee‚ soda‚ and tea. I am going to get ahold of an egg and let the egg saok in the diffrent solutions. Coffee is a beverage that is made of roasted or baked beans of several spices‚ that is why people call them coffee beans. Soda is a carbonated soft drink. They have diffrent artifical sweeteners. Just like tea and

The water came from outer space to Earth. The water was brought to the planet for the comets. The water has a different structure for each state (gas‚ liquid‚ ice). Liquid water has random molecules. On the other hand‚ the ice has a more stable structure. The different structure between ice and liquid water can explain why the ice has less density than liquid water. Temperature is responsible for increasing the dissolution of components‚ and electrical conductivity. Pure water is not a good conductor

The Different Types and Affects of Schizophrenia Approximately 2.4 million Americans are affected with Schizophrenia. Currently one percent of that population develops Schizophrenia at some point in their lifetime (National Women’s Health Research Center) (web 3 June 2010) . Schizophrenia is when an individuals thinking‚ emotions‚ and behavior is impaired. If untreated‚ Schizophrenics will soon start to make a person withdraw from interactions with others and will eventually they will not be

I am investigating how the rate of reaction differs when we change the concentration of Hydrochloric Acid whilst reacting with Magnesium. The rate of reaction is explained by the Collision Theory. This theory explains how various factors affect the reaction rates and how chemical reactions occur. The 4 factors of the Collision Theory are: • Temperature • Concentration • Surface area • Catalyst I am investigating how different concentrations of acids affect the rate of reaction. However I must

Technique of Water Evaporation Introduction When water evaporates from water storages it becomes a major issue that affects regions of agriculture in most lands leading to annual loss exceeding potentially to 40 precent and more of water storage. This water which is lost leads to reduction of productivity in agriculture affecting the environment adversely. Literature review has been developed on the same by various researchers in order to develop evaporation suppression techniques

As well as when the blood volume and flow return to the heart‚ it increases which makes the left ventricle expand and adapt to a different situation. Due to this‚ the heart can register a higher level of blood and eject it at a faster rate to all living cells and membranes. This increases the heart rate because the movement of blood is faster than the resting heart rate. When performing a strength training exercise‚ the muscles contract allowing blood vessels to pass in and out. This builds the pressure

Materials in nature can be divided into different phases‚ also called states of matter‚ depending on the mobility of the individual atoms or molecules. The obvious states of matter are the solid‚ the fluid and the gaseous state. In the solid state‚ intermolecular forces keep the molecules close together at a fixed position and orientation‚ so the material remains in a definite shape. In the fluid state‚ the molecules are still packed closely together‚ but they are able to move around. Hence a fluid

Liquids & Solids Pre Lab Questions: 3pts 1. What are the learning goals of this lab? The learning goal of this experiment is to view and experience the melting point and boiling point of different substances. 2. Why is acetamide not allowed in contact with your skin? What precautions does one have to take to work with this chemical? Acetamide is a carcinogen‚ which can cause cancer. Therefore‚ it should not be allowed to come in contact with a person’s skin. Any person working with this chemical
