that I obtained were percentage increase or decrease in the length of the potato. I used the following instruments to collect my results: Cork Borer (size 5), Measuring cylinder x2, Test Tube rack, Three test tubes, Vernier Calipers, Scalpel, White Tile, Brush. No attempt at great accuracy was made. The experiment was only an indication of what length of potato chip `I should use. I decided to use the three cm lengths of potato chip because it gave a bigger percentage change therefore I

• osmosis in potato chips

as the water, of higher concentration inside the potato cells, flows down a concentration gradient into the solution, which has a lower concentration of water molecules. If we say that the percentage change when the potato is placed in the 1M solution is x%. I predict that when the solution is 0.5M the percentage change will be 0.5x%, and when the solution is 0.25M strength I hypothesise the change will be 0.25x%. Variables Description: Dependant Variables The dependant variable is plotted on the y-axis

• Tennis Ball Investigation

(point A), the more energy is converted to kinetic energy while the ball is dropping and then to elastic potential energy (E.P.E) while it is static on the floor (point B). At this point the ball looses a percentage of its energy to sound and heating the floor. I know that it is a percentage of its energy that it looses rather than a fixed amount because I know that the more energy the ball has the louder the

certainly a poverty-level lack of income won't help in child rearing. Education is another important factor to consider. The United States Department of Education reported the national average percentage of high school seniors who graduated during the 1992-1993 school year was 71.1%. Maine's percentage was 74.3, while California posted 67.9% (1). I believe this is due to a much smaller population, which, in turn, produces smaller schools. Student-to-teacher ratios tend to be much smaller. I graduated

• Define And Explain Price Elasticity of Demand

usually negative. There is an alternative scenario where demand will increase as price does so too. This happens only in the case of Giffen goods, where elasticity is positive. The formula for price elasticity of demand is: Percentage Change in Quantity Demanded Percentage Change in Price One determinant of price elasticity is the number and closeness of substitutes there are available for a good. The closer the goods are, the greater will be the price elasticity of demand of that good. The reason

Preparing Benzoic Acid from Benzylalcohol Planning (a) Problem The aim of this experiment is to synthesize benzioc acid, with the highest possible yield, by oxidizing benzylalcohol. Hypothesis We expect the percentage yield to be about 50% due to several processes such as cooling and filtering. Possible Variables - Time - Temperature (of water) - Filter Planning (b) Apparatus/ Materials - Round bottomed flask under reflux - benzylalcohol - HCl - Na2O4

• Investigate how PH Affects the Ability of Raw Meat to Absorb Water

calculate the percentage change in mass so that I can compare the different results with each other. I will calculate the percentage change by : Change x 100 Original · Controlled Variables The main control variables for this experiment are : Each of the 5 buffer solutions should have the same volume of 50ml and the same concentration. If one beaker had more than another then there would be more solution to act on the meat therefore tenderising it more. This could alter the end percentage change in

impure citric acid required to neutralise a known volume of 1.0 M sodium hydroxide. Consequently, by calculating the correct volume of pure citric acid that would be required to neutralise this volume of sodium hydroxide, I can calculate the percentage purity of the citric acid. Calculating the Amount of Citric Acid ------------------------------------- In order to make this experiment a good titration, I must use a reasonable amount of citric acid. This is so that the amount of citric

the percentage of change of the quantity demanded is greater then the percentage change in price, the demand is known to be price elastic. On the other hand, if the percentage change in demand is less than then the percentage change in price; Like that of demand, supply works in a similar way. When the percentage change of quantity supplied is greater than the percentage change in price, supply is know to be elastic. When the percentage change of quantity supplied is less then the percentage change
