tubes contain mercury. The diameter of one vessel is four times larger than the diameter of the other. A column of water of height 70cm is poured into the narrow vessel. How much will the mercury level rise in the other vessel and how much will it sink in the narrow one? How much will the

Welter-Weight of plant growing: Water VS other liquids Purpose of Project The purpose of this project is to see if there is a difference in how plants grow based on what they are watered with. By watering five different plants with five different liquids and measuring them daily we will prove or disprove the hypothesis. Problem of the Project Different liquids contain different additives and nutrients that could potentially affect the growth of a plant. This project will reveal how different

sample from a preloaded pipet. Be sure to wear goggles while doing this test. 13. To test for glucose bring a beaker of water to a boil. Label each of the test tubes of water samples to ensure you can decipher which tube has which substance in it. Then put seven or eight drops of the Benedict’s solution each test tube and place them in the boiling water. If there is glucose in the water, they will turn yellow or bright orange and opaque. 14. In a table record which tests results were positive and which

“GROUND WATER AND ARTIFICIAL RECHARGE IN GUJARAT” ABSTRACT Though groundwater is an important source of irrigation in India, its availability is non-uniform in space and time. In Saurashtra region of Gujarat state, problem of groundwater depletion has arisen due to high withdrawal than rate of replenishment of groundwater. This also resulted in seawater intrusion in coastal areas at very high rate. The water harvesting and groundwater recharge activities played an important role in increasing the

Activities Human activities pollute air, water and land in different ways. Oil spills are becoming a large scale problem, causing devastating effects to marine wildlife. The oil is almost impossible to clean up, spreading over large areas very quickly. Even solutions designed to dissolve the oil can cause an imbalance in the ocean environment. Much water pollution is also caused by sewage and fertilizers seeping into water and starting the process of eutrophication

As dams retain about two- thirds of our consumed water (Conservation Fund, 1984), irrigate farm lands worth in excess of 9 billion dollars, are visited by almost a billion people a year for recreation (Bureau of Reclamation, 1991), and provide about a tenth of our countries electrical power t Statistical

Aim: To investigate how carbon dioxide can affect the rate of photosynthesis. Hypothesis: The rate of photosynthesis in the water plant hydrilla will change as the rate of carbon dioxide changes. Background information: Photosynthesis Photosynthesis is the process of autotrophs turning carbon dioxide and water into carbohydrates and oxygen, using light energy from sunlight. Autotrophs are organisms that are able to produce nutrients and organic compounds using inorganic materials. Examples of

temperature (T) for each trial. Record in Data Table 2. Trial # Tf Ti T Trial 1 -3 20 -3 -20= -23 Trial 2 -2 20 -2- 20 -22 2. Did the temperature of the water rise or fall when the NH4NO3 was added. Explain this in terms of heat transfer. -The temperature of the water fell because the NH4NO3 absorbed the heat of the water. 3. Calculate the heat ( q in joules ) for the reaction. Record q for each trial in data table 2. Trial 1 Trial 2 Avg Q = ? Q = ? Q = ? M=25g M=25g M=25g

WATER CYCLE Water Cycle, also known as hydrologic cycle, is a process that is constantly recycling the Earth 's supply of water. This is important because humans, animals, and plants all need water to survive. It is controlled by the sun, which produces energy in the form of heat. This heat energy causes the water in the world 's oceans, lakes, etc. to warm and evaporate. As the water is heated, it changes its phase from liquid to gas. This gas is called water vapor and this process is called

shows with the shrinkage of the potato. 5. Explain the trends observed in the group’s data: The trends showed that with distilled water the mass increased within a time range which showed that osmosis was taking place so the cell were rigid and the weight of the potato increased then it started decreasing in mass which shows that it started losing water but then after 25mins it regained its rigidity by absorbing more
