Well‚ we could provide more Sainik Schools and those who feel like completing their first to 10th grade education through such schools are welcome to join. We already have such schools in India and we can build some more. Miltary Training instill a sense of pride‚ nationalism‚ and patriotism l think the Army Cadet Force should be more advertised for the benefit of adults and kids. It teaches discipline and respect for yourself as well as for others. As an adult you can obtain training and play

EFFECT OF TEMPERATURE ON CORROSION OF CERMETS ALLOY ABSTRACT Tungsten carbides (WC) are widely used as wear resistant components such as seal‚ valves‚ rings‚ nozzle and bearings. But in some processing operations‚ the environment necessarily includes severe corrosion or extremes of temperatures. In this research‚ commercially cobalt tungsten carbide (WC-6%Co) and nickel tungsten carbide (WC-9%Ni) was examined in seawater (3.5% salinity) to know the effect of temperature on corrosion for both

is which type of temperature change will result from heating ice to liquid‚ then boil (steam)? What will happen to the water after the boil? I hypothesise the water heats ice to liquid and then goes to simmer and boil. The independent variable is the hot plate changed to a burner itself. The dependent variable is what we are measuring is the time. The steps in the lab were to first start off with a burner‚ ice and water in a beaker‚ then record time and water temperature. Also‚ some phase

Concentration‚ pH and Temperature on Enzyme Activity Biology For Majors October 4‚ 2012 Abstract We examined the reaction an enzyme has when its concentration‚ pH and temperature are altered. In order to do this‚ we added different levels of pH into different test tubes with the enzyme (sucrose)‚ and substrate (sucrose)‚ and we then inverted the tube. The higher pH produced more enzyme activity. Temperature effects enzyme activity by decreasing its stability when the temperature increases. Oppositely

Effects of Temperature and pH on Catalase Activity INTRODUCTION Enzymes are organic catalysts that spur metabolic reactions. The presence of an enzyme within a cell is essential in order for any sort of reaction to take place. All enzymes are complex proteins that act in an organism’s closely controlled internal environment. In such a homeostatic environment‚ the temperature and the pH (concentration of hydrogen ions)‚ remain within a fairly narrow range. Extreme variations in pH and temperature

glucose to a solution of KMnO4 and H2SO4‚ the solution will turn colourless and it will take a specific time for the reaction to complete. By increasing the temperature‚ the time it takes (the rate) for the solution to completely change to colourless will be increased. Thus it can be said‚ that it is being hypothesized that an increase in temperature will cause an equal increase in the rate of the reaction. Method:1). Using a measuring cylinder‚ place 50 cm3 of sulphuric acid into a 250 cm3 beaker‚ add

the freezing point depression of a known amount in an aqueous solution. Freezing point depression is a colligative property of solutions. There are three other properties‚ which are boiling point elevation‚ vapor pressure depression‚ and osmotic pressure. Colligative properties of a solution depend on the amount of solute and solvent molecules and not the specific properties of the molecules. The temperature at which the solvent starts to freeze will be specified as the freezing point of the solution
