Mung Bean Growth with Different pH Levels Through this experiment‚ the objective was to find which pH liquid created the best environment for the Mung beans to grow. First‚ the beans were placed into bags with different pH liquids. Then‚ measurements were taken each day to monitor the growth average of the beans. The pH 2 beans average size at the end of the experiment were 0.24 cubic centimeters‚ the pH 7 size average was 0.38 cubic centimeters‚ and the size average of the pH 2 beans was 0.24

The effect of temperature on a reaction rate In this experiment I shall be investigating how temperature affects the rate of reaction Rates of reaction The Factors that affect the rate of reaction are temperature‚ surface area‚ concentration‚ catalysts‚ light and pressure Surface area – Surface area is the amount of solid surface that is available for reaction - Only affects solids so this will not affect our

is the temperature at which water changes phase from a liquid to a solid or vice versa. The freezing point describes the liquid to solid transition while the melting point is the temperature at which water goes from a solid (ice) to liquid water. In theory‚ the two temperatures would be the same‚ but liquids can be super cooled beyond their freezing points so that they don’t solidify until well below freezing point. Ordinarily the freezing point of water is 0° C or 32° F. The temperature may be lower

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

Despite all the downsides‚ there is a small hint of people benefiting from being in poverty. Being in poverty can help people appreciate the little things in life; this is exactly the message that Barbara Kingsolver relays in her book The Bean Trees. The Bean Trees is a story set in 1970’s Kentucky and Arizona about Taylor‚ a young woman growing up and becoming independent who has been affected by poverty her entire life. As the story unfolds and Taylor’s character is developed it is shown

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

Introduction: Farming corps is the most important process for the survival of human race. The plants not only provide food for our bodies but it also helps provide the oxygen we breathe. They clean the air in a process called photosynthesis. This experiment tests if pinto bean seeds germinate better
