Spirit Burner Experiment Aim: To perform an experiment in the labs to determine the heats of combustion of selected alcohols and then to use this information and the gathered data from chemical data sources to determine trends in the longer chain alcohols. The Variables that MUST be controlled throughout the experiment are: • The height from spirit burner nozzle to the base of the water filled beaker • Air drafts around the room must be kept to minimum so as to keep the heat on the base of the

Pipe Flow Experiment Purpose The purpose of the experiment is providing an opportunity to students of experience to familiarize with some key aspects of fluid flow in pipe‚ notably friction losses and verify theory. In this experiment‚ required equipment are a water tank‚ piezometric tubes‚ pump‚ a stop watch‚ empty bucket and a digital weight scale. By operating the pump to keep the water is full in the water

I will use cress seedlings‚ which germinate quickly and can grow a few centimetres in a matter of days and sodium metabisulphite‚ which reacts slowly with water to produce sulphur dioxide gas. The seedlings will have to be in an enclosed system so the sulphur dioxide does not escape. The experiment is a simulation trying to model a powerstation

Therefore the beetroot used should be freshly cut. pH The pH is also an important factor‚ as pH can have an effect on the weak interactions and bonds that bound the membrane together. To keep the pH constant it is important to make sure that the same surrounding are used for the experiment. Surface area. The surface area of the beta
