I am choosing to study how the PSI (pounds per square inch) of a football is affected by the temperature. I chose to study this because I like football and I always pondered this question. I believe that this is a worthwhile question to study because these studies can help improve the game as the weather gets colder. As air cools‚ it expands‚ so when a football gets colder‚ the air inside it expands. This expansion causes the air pressure to decrease. The air pressure decreases because the molecules

Place the first food item under the ring stand. 6. Set the food on fire then quickly place the can on the ring stand above the burning food. 7. Once the food has extinguished take the temperature of the water in the can. 8. Weigh the food that has been burned. 9. Pour out water that is in the can. 10. Repeat steps 2-9 for

type of reaction where a molecule is broken down into smaller pieces is called an anabolic reaction. Hypothesis The prediction would be such that as the substrate concentration increases‚ the rate of reaction will go up at a directly proportional rate until the solution becomes saturated with the substrate hydrogen peroxide. When this saturation point is reached‚ then adding extra substrate will make no difference. The rate steadily increases when more substrate is added because more

Effect of Temperature on Enzymes ~Abstract~ In this experiment the effect of different types of temperatures on enzyme activity was examined. The temperature baths that were used to test the difference in enzyme activity on fresh liver were; 4 °C‚ room temperature which was 22°C‚ body temperature which is 37°C‚ and 77°C. The total time of each trial was 2 and a half minute‚ 1 minute for the H2O2 to acclimatize to the temperature‚ 1 and a half minutes for the reaction to occur. Catalase causes Hydrogen

If you’re a solid you are confident in your decisions‚ which is a great strength; you will make decisions easier and faster than someone who’s questioning themselves. While being confident is a strength of being a solid it is also a great weakness. A confident person will not second guess their decisions;

investigate the effect of temperature on the enzyme catalase. The original research question was exploring the effect temperature would have on a yeast catalase reacting with hydrogen peroxide (H2O2). To address the latter question a series of experiments were conducted. The various temperatures experimented with were as follows: 22 degrees Celsius (room temperature)‚ 0 degrees Celsius (freezing)‚ 100 degrees Celsius (boiling)‚ and 37 degrees Celsius. Along with variations in temperature‚ the experiment involved

CALIBRATION OF TEMPERATURE AND PRESSURE SENSORS Mechanical Engineering Department Loyola Marymount University Los Angeles‚ California ABSTRACT In this laboratory experiment‚ an Omega Model PX- 236-060GV piezoresistive pressure transducer was calibrated‚ by using an AMTEK model deadweight pressure tester. For the temperature calibration an Jofra Model C-140 temperature calibrator was used. The experiment began by setting up the Jofra Model C-140 temperature calibrator‚ and taking data from

Usman Omid Biology IB 1A The Effect of Temperature on Beetroot Membranes _Aim_ This practical will test the effect of temperature on the integrity of the membranes‚ _Introduction_ The cells of beetroot contain a pigment called betalain in their vacuoles. It is kept inside the cells by the membranes. If these membranes are damaged‚ then the betalain leaks out. The amount that leaks out can be assessed‚ as the leaked out pigment will color the water surrounding the cells. This information can

particles either consist of particles that are either hot or cold. High temperature bodies‚ are often caused due to the high heat transfer‚ which is created by chemical reactions‚ nuclear reactions‚ electromagnetic dissipation‚ or mechanical dissipation. Heat is generally transferred between two different objects by radiation‚ conduction and convection. Heat is only passed on between objects‚ with the help of different temperatures.
