17th‚ October 2010 Margarita SA: VOL RATIO AND AGAR BLOCKS Conclusion: For this experiment the agar jelly had to be cut in to five different block sizes‚ after that has been done we had to add all five blocks in to the test tube with the acid and time to see how long it would take for the colour to change from a pinky purple to clear. From this experiment I learnt that the bigger the size of the jelly is the

Introduction For this experiment‚ we are going to determine the effect of temperature on solubility‚ to be done in a chemical by dissolving a solute in a definite amount of solution which is saturated. Specifically‚ the goal of this experiment is to prepare a saturated solution of Na2C2O4 in water at different temperatures‚ determine the effect of temperature in solubility‚ and to apply Le Chatelier’s Principle. We can do all this by simply titrating a certain amount of standard KMnO4‚ and measuring

substances catch fire at a different temperature. The lowest temperature at which a substance catch fire is called its ignition temperature. Combustible substances do not catch fire or burn as long as its temperature is lower than its ignition temperature. Now let me do an activity which tells you why reaching ignition temperature is necessary to burn an object. You know that paper catch fire with a flame. Let me

Heat‚ Temperature‚ and Phase Changes Assessment Practice Answer This graph shows what happens to the temperature of the water‚ while it was boiling in a kettle‚ as heat energy was being added to it and what the water was doing will it began to warm and change states. During a phase change‚ the temperature remains mainly constant. This occurs because the heat energy is used to break the bonds between the ice molecules as they turn into a liquid phase. It is possible to constantly

EXPERIMENT-1 Pressure-Temperature Relationship for Steam OBJECT: The objective of this experiment is to determine the relationship between saturation pressure and saturation temperature of the wet steam. APPARATUS: Pressure-temperature apparatus with pressure gauge and thermometer. [pic] THEORY: In order to determine the relationship between the saturation temperature and pressure of wet steam it is necessary to obtain a number of corresponding values of the

Summary Hampton Machine Tool Company was established in 1915‚ whose customers were aircraft and automobile manufacturers located in the St. Louis area. The company had a large success rate throughout the 1960’s‚ with an unfortunate decline throughout the mid 1970’s in sales. The company was able to recover in the years following due to a large increase in military aircraft sales‚ especially the company’s conservative financial policies. Mr. Benjamin G. Cowins‚ president of Hampton Machine Tool Company

Objective The objective of this experiment is to study Newton’s Second law of motion utilizing the Atwood Machine and to show that the acceleration is proportional to the force causing the motion. Theory Newton’s second law of motion states that the acceleration of an object is directly proportional to the net force acting on the object and inversely proportional to the total mass. a = net force/ total mass If an object is acted on by a net force ‚ it will experience an acceleration that

They were originally designed to machine metals; however‚ with the advent of plastics and other materials‚ and with their inherent versatility‚ they are used in a wide range of applications‚ and a broad range of materials. In machining jargon‚ where the larger context is already understood‚ they are usually simply called lathes‚ or else referred to by more-specific subtype names (toolroom lathe‚ turret lathe‚ etc.). These rigid machine tools remove material from a rotating workpiece
