Biology coursework How does the temperature affect the rate of reaction? Introduction For our experiments‚ I was investigating what affects the rate of reaction. We used Hydrogen peroxide to test the rate of reaction‚ with the temperature of this being our variable that we changed. Hydrogen peroxide is a clear‚ colourless liquid which has various amounts of uses within the laboratory‚ industrial purposes and even in our households. It is mainly used for cleaning products and hair dye but is

While fire investigators were required to be up-to-date to fire science and must upheld a certain standard of knowledge in what to look for to determine whether or not a fire-related incident is arson‚ being “up-to-date” in science‚ especially back in the 70s‚ does not mean courts will always come to the correct conclusions. In my first position paper where I explored the history of fire investigations and concluded why fire science is important
