Iodine clock reaction This is the hydrogen peroxide/ potassium iodide ‘clock’ reaction. A solution of hydrogen peroxide is mixed with one containing potassium iodide‚ starch and sodium thiosulfate. After a few seconds the colourless mixture suddenly turns dark blue. This is one of a number of reactions loosely called the iodine clock. It can be used as an introduction to experiments on rates / kinetics. 63 Lesson organisation This demonstration can be used at secondary level as an introduction

As they only provide the user with the video of any incident‚ which is of no use when it comes to stopping the incident from taking place if there is no one is present monitoring the screens at that point of time. This project will allow only the registered user to turn on the tracking system. This project will keep the information of every tag that has been

air-conditioning‚ heat pump and refrigeration systems. The term is defined as the ratio of energy consumption in kW to the rate of heat removal in tons at the rated condition. The lower the kW/ton the more efficient the system. KW/ton = Pc / Er (1) Where Pc = energy consumption (kW) Er = heat removed (ton) Coefficient of Performance - COP The Coefficient of Performance - COP - is the basic parameter used to report efficiency of refrigerant based systems. The Coefficient of Performance - COP
