How does water temperature affect the amount of dissolved oxygen? Ⅰ. Introduction Dissolved oxygen is just one of the many ways to measure water quality. It means the volume of oxygen that is contained in water. The amount of dissolved oxygen in water usually determines the quantity of organisms living in that water. Dissolved oxygen levels vary by how much oxygen the water can hold‚ how much oxygen is produced by photosynthesis‚ and how much oxygen is consumed by respiration. If water is too warm

How does the temperature of water affect how fast sugar can dissolve? Predict We will do three different tests‚ dissolving the water in boiling‚ warm and cool water. The sugar in the boiling water will dissolve the fastest. The sugar added to the cool water will dissolve the slowest. Reason According to the state of matter theory‚ the particles in a gas move faster than in a liquid‚ which I will use to infer that the hotter the water is and closer to a gas‚ the faster the particles move. Therefore

experiment explores how salt and sugar affect the melting rate of ice in water. Research Questions: * Does adding salt to ice and water slow down‚ speed up‚ or not change the rate the ice melts in the water? * Is salt the only substance to have this effect? What about sugar? Knowing how to speed up the melting rate of ice is very important information for anyone who needs to de-ice roads or driveways after a winter storm. While it seems simple‚ adding salt to ice water actually activates

the sucrose solution and distilled water have on the plasmolisys of epidermal cells of a red onion. Hypothesis: Taking in consideration osmosis‚ and my knowledge about it‚ my prediction is that as the molarity of the solution under which the cells are exposed will increase‚ also the amount of plasmolysed cells‚ counted from amount of undamaged cells taken into account‚ will also increase. Hence‚ theoretically‚ the amount of plasmolysed cells in distilled water should be 0‚ while at 1mol solution
