possible factors that might affect how quickly a sugar cube dissolves in water temperature of water/liquid water being shaken water being stirred the sugar lump being loose amount of sugar in the cube In this experiment‚ I will be investigating if the change in water temperature (independent variable) would affect the time it takes for sugar to dissolve (dependent variable). Aim The aim of this experiment is to find out if the water’s temperature would affect the time it takes for sugar

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

of positive and negative charges that are useful in order to conduct energy. Simultaneously‚ we have also found out that saltwater conducts energy because of the solid salt it contains and when it is dissolved into water‚ the elements sodium and chloride from the salt separate or break up because of the very reactive traits of water (H2O)‚ thus‚ causing the production of positive and negative ions that are able to carry energy and consequently conducting electricity. The particular

FREEZING FOODS 1. Freezing storage space is valuable. Use it only for high quality meats‚ fruits and vegetables. Do not freeze and store excessively bulky products. 2. Place a variety of foods in your locker or home freezing unit. Avoid long storage of any items. Add new items as rapidly as storage space will permit. 3. If your locker plant or home-unit has a quick-freeze compartment‚ use it. The temperature of this compartment should be held at 0 or below. The time required for freezing should not

1 October 2010 Salt Water Pool Systems vs. Liquid Chlorine Pool Systems I currently utilize a salt water pool system called an Aqua Rite System. If you’re in the market for a pool‚ it can be a bit overwhelming to choose a type of system that is right for you. The salt water pool vs. chlorine pool battle has been raging over the last decade‚ and today‚ many home owners are building these systems right from the start or converting their old chlorine pools into a salt pool. But what is the real

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
