The Effect of pH Level of a Liquid on the Rate of Corrosion of Copper wire In this experiment‚ I will be testing the corrosion rate of copper wire after leaving them in different liquids with different pH levels. By doing so I will be able to determine which pH level corrodes copper the fastest. I will conduct this experiment by pouring 250mL of different liquids with different pH levels in cups‚ followed by an iron strip placed into the cup. A stopwatch will be timing how long it takes the iron

Research question/Aim Extract copper from copper oxide by reduction using butane gas Hypothesis The butane gas will reduce the copper oxide and leave behind pure copper. This will allow us to find the empirical formula of the copper oxide as well as the masses of oxygen and copper Variables Dependant variable The dependant variable will be the reduction of the copper oxide which will be calculated at different temperatures. Independent variable The independent variable here

Body Composition Body composition is the proportion of fat‚ muscle‚ and bone in the body. There are many methods to know someone’s body composition and body fat percentage such as measurement with calipers‚ underwater body‚ fat test‚ the bodpod‚ DEXA scan and bioelectrical impedance analysis. (Kravitz‚ Len‚ Ph.D. & H. Heyward‚ Vivian‚ Ph.D.). The calipers method involves measuring the skinfold thickness of the layer of fat just under the skin in several parts of the body with calipers.
