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

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 50 cm3 of water using the same

he scientific method‚is a method or procedure that characterizses science according to the observations‚measurements‚tests‚and the hypothesis of an experiment.The scientific method has been around since the Renaissance began to do the studying of what inductive reasoning was‚going all the way back into the 10th Century. Even though it was founded by many philosophers its said to have derived mainly from two contibutors; Aristotle and Greek philosophers.Aristole‚aj ancient greek philosopher who invented

experiment was to determine the effect of temperature on the rate of movement of Porcellio scaber. Our prediction was that P. scaber would have faster rates of movement in hotter temperatures. We expected this response as P. scaber is an ectotherm. Hence‚ its body temperature is directly determined by the temperature of its environment (Mellanby 1939). Løkke and van Gestel (1998) stated that the rate of the metabolism is controlled by the environmental temperature for ectotherms. As seen by Wieser

generations to ponder on the meaning of science‚ the methods to find truth‚ is one of the most influential philosophers of the 20th century. Of particular importance to scientific methods of inquiry is the brawl between the development of theory and the criteria for science. In Popper’s own words‚ it is in this brawl that Popper decided to “grapple with the problem: When should a theory be ranked as scientific? or Is there a criterion for the scientific character or status of a theory?” (Popper 1957)

INVESTIGATING THE EFFECT OF TEMPERATURE ON THE RATE OF ENZYME ACTIVITY. To investigate the effect that temperature has on enzyme activity I am going to use the enzyme amylase‚ which is used as a biological catalyst to break down starch‚ which cannot pass through the gut wall due to the size of the molecules‚ into smaller ones. Amylase is a carbohydrase‚ which converts starch to simple sugars in the Salivary Glands. Three features of all enzymes are: They are always proteins. They are specific

sINTRODUCTION What are Carbon Credits? A carbon credit (often called a carbon offset) is a financial instrument that represents a tonne of CO2 (carbon dioxide) or CO2e (carbon dioxide equivalent gases) removed or reduced from the atmosphere from an emission reduction project‚ which can be used‚ by governments‚ industry or private individuals to offset damaging carbon emissions that they are generating. How are Carbon Credits used? Carbon credits are associated with either removing existing CO2 or
