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

Global Wind The region of Earth receiving the Sun’s direct rays is the equator. Here‚ air is heated and rises‚ leaving low pressure areas behind. Moving to about thirty degrees north and south of the equator‚ the warm air from the equator begins to cool and sink. Between thirty degrees latitude and the equator‚ most of the cooling sinking air moves back to the equator. The rest of the air flows toward the poles. The air movements toward the equator are called trade winds- warm‚ steady breezes

research task 1. Explain the difference between a prominence and a solar flare? Prominence are huge loops of gas that connect different parts of sunspot regions. A solar flare is an explosion caused by hydrogen getting really hot‚ the gas shoots out into space causing a solar flare. 2. Use a diagram that describes what causes the aurora? 3. Diagram that demonstrats the annular eclipse? 4.Is 2500 a leap year? NO 5. Compare the geocentric and the heliocentric models? Geocentric - model

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
