    looking daily at the thermometer, which is filled with mercury. What L.P. Hartley symbolises with the thermometer is the heat of the relationship between Marian and Ted, one which Leo is unknowing of. Leo is waiting for the thermometer, between himself and Marian to rise significantly, which is why he checks the thermometer daily for a rise in temperature. “The thermometer stood at 84.” “But I was confident it could do better.” This shows the dedication of Leo to the mercurial thermometer . His twelve year

    Some of the factors are thermometer was calibrated to determine its precision. The actual melting points of water, phenylacetic acid, o-anisic acid, and benzilic acid to their observed melting points were determined by calibrated thermometer. Then the solubility tests were run in order to determine the appropriate solvent for the unknown solute (Table 1). After determination of a solute

  • Exothermic Reactions Lab Report

    Introduction This project used four different exothermic reactions to boil one litre of water, in doing this the reactions’ economic and environmental friendliness were tested and compared. The following exothermic reactions were tested: the combustion of charcoal, the combustion of wood, the combustion of propane gas and the combustion of hydrogen gas. It is important to note that we did as much as possible to carry out all the experiments fairly, however we faced a few difficulties and were not

  • Commercial Headache Powder Lab Report

    Aim This experiment separates the constituents of a commercial headache powder employing the use of extraction method. The active ingredients of the commercial headache powder were extracted by dissolving the powdered tablet in propanone solvent. The suspended fine particle binders in the propanone solution were removed by filtration method. The solid analgesia was obtained by evaporating propanone solvent. It was then collected on Hirsh funnel by filtration. Melting point determination was performed

Afterwards, the beaker was placed on the hot plate. A thermometer was also placed in at an angle. After ten minutes the thermometer was adjusted until it was completely straight in the middle of the beaker. Then the hot plate was turned on. One group member monitored the hot plate, while a second group member retrieved a stirring stick to stir

  • Goldfish Temperature Regulation

    702 Words  | 3 Pages

    Temperature regulation is one of many aspects of homeostasis, the ability to maintain an organism’s internal environment at a comfortable temperature. An organism can be a temperature regulator or a temperature conformer. An endotherm is a regulating organism that maintains homeostasis by producing its own heat thus keeping the internal environment stable regardless of the conditions of the external environment. This means that the metabolism of an endotherm is always at a constant, rapid rate. An

    Sodium bromide and 1-butanol are dissolved in water since the bromide ion from the sodium bromide and the four carbon chain from the 1-butanol are the desired components of 1-bromobutane. In order to get the sodium bromide and the 1-butanol to react sulfuric acid is added to react with the sodium bromide and combine with the sodium ion producing hydro-bromic acid. Later, when the flask is heated the bromide ion will be able to combine with the four carbon chain of the 1-butanol. During the process
