To prepare the tub‚ we filled the tub with 9 degree Celsius water. 8. Then we filled a graduated cylinder with water of the same temperatures of the tub: 9 degrees Celsius to the very top of the graduated cylinder. 9. One person flips the graduated cylinder into the tube. 10. At the same time‚ another person flips the test tube with hydrogen peroxide and sticks

Celsius 233: Clarisse the Catalyst “We are like chameleons; we take our hue and the color of our moral character‚ from those who are around us” (John Locke‚ English philosopher and physician). Everyone in the world influences others in many various manners. The influence can be diminutive or extremely significant but they always have an impact. In the novel‚ Fahrenheit 451‚ Ray Bradbury introduces a string of influential figures that drive the protagonist‚ Guy Montag‚ through a complete

Introduction In this experiment‚ we will be figuring out how much does 80 degree celsius water reduce in temperature in 15 minutes‚ using different materials to insulate the heat. The five materials that will be tested are: Aluminium foil‚ plastic wrap‚ newspaper‚ felt‚ and bubble wrap. Aluminium foil is a reflective material; this means that it bounces the thermal energy back to the foiled object. It also absorbs the heat. Not only does it stop heat loss‚ but Aluminium foil is also useful for

Tutorial 1: How to plot and Interpret a Climograph. Q3: Dublin has a significantly low rainfall measure‚ although it is known as a rainy city‚ it more than likely won’t last long. I think it stays the same temperature because of its location in Ireland. Q4: The similarities between the Climographs for Plymouth and Krakow are that they have the most rainfall at the same time of the year‚ with the highest inch of rainfall beginning in May/June and hitting the highest in July. A difference between

Principles of Cellular Respiration Ashley Flannigan November 5th‚ 2013 Professor Ryan BSC2010 Lab Fall 2013 2220 ABSTRACT Students in a Biology 1 lab class constructed an experiment on Cellular Respiration by investigating the effects of temperature on crickets’ metabolic rate. By following the following procedures out of the Lab Manual‚ the students were able to find an almost accurate representation of the crickets’ cellular respiration rate under various temperatures in order to

substance we used was Biphenyl. 68 degrees Celsius is the known melting point. We used the capillary method and observed the melting point using a Mel-temp device. The next substance whose melting point we observed was 90 % Naphthalene‚ 10 % Biphenyl. In the last part of the experiment I observed the melting point of Unknown E. After finding the melting point of Unknown E‚ I used 2-Chloroacetemide with a known melting point between 116-118 degrees Celsius and mixed it with Unknown E. I also took

Phase Change Lab Written Response Our objective in our phase change lab was to record observations of the increase in temperature (in Celsius) as water changed from solid to liquid to gas over a hot plate. This lab report will discuss quantitative and qualitative data contained in the lab‚ how energy is related to phase change in water and an elucidation of how melting point and boiling point relate to the physical properties of matter. This paper will basically outline the lab done in class
