    Absolute zero is the lowest possible temperature, where nothing could be colder and no heat energy remains in a substance. The absolute zero value of an experiment is the temperature at which entropy reaches its minimum value. The theoretical values for absolute zero is 0 Kelvin (-273.15 ◦C or -459.67 ◦F). This principle applies to the experiment as it explains the value at which a gas would theoretically have a volume of 0 mL and would therefore take up the least amount of space. Theoretically, if a person could get the temperature of propane to 0 Kelvin, the volume of this gas would be 0…

    Introduction: There is a direct relationship between temperature and pressure in gases. The relationship can be proven by measuring pressure, which is measured with a pressure sensor, and temperature, which is measured with a temperature probe. Two areas remain constant throughout this experiment, which are volume of the gas and the number of molecules the gas itself contains. In this experiment, using the constructed apparatus, an Erlenmeyer flask with an air sample will be placed in four…

    the Natural Philosophy department as Glasgow at the age of ten to further his studies. He received his education from Cambridge University where he earned a bachelor’s degree. Thomson lived a life of curiosity that led his to his discoveries. Before his death he had a total of seventy inventions and over 650 papers published. Although Thomson’s ideas and inventions aided several fields of studies, his major contributions changed the physics world in major ways. If I mentioned the name William…

    scientists named Eric Cornell and Carl Wieman, from the University of Colorado, created the first BEC. They used two-thousand rubidium-87 atoms to make it, and laser cooling and magnetic evaporative cooling to cool it. Four months later, Wolfgang Ketterle condensed sodium-27 atoms at MIT. “Bose–Einstein condensates are extremely fragile. The slightest interaction with the external environment can be enough to warm them past the condensation threshold, eliminating their interesting properties and…

    RESEARCH QUESTION: This experiment will analyse the changes in performance of a cane toad in abiotic factors, such as temperature. HYPOTHESIS: Cane Toads exposed to a warmer temperature will more times per minute compared to cane toads exposed to a cooler temperature. METHODS: 16 cane toads were kept at a constant temperature in an insulated container (two treatments: 8 in 25 degree Celsius and 8 in 15 degree Celsius temperate environments). Toads were then taken out, one by one, and placed…

    Copenhagen who later inspired him to construct a mercury thermometer. Roemer has constructed a spirit thermometer with an upper fixed point determined by the temperature of the boiling point of water and a lower fixed point determined by the temperature of melting ice. The two measurements were marked with 60 degrees and 7 to half a degree respectively. Roemer’s scale sustained the temperature of a mixture of salt, ice and water which was considered to be the coolest temperature of his time.…

    Introduction: Aerobic cellular respiration is the process in which energy is being released from organic compounds by chemical oxidation. In this lab we compared the change of the consumption of oxygen in germinating peas as it underwent changes in temperatures of either ten degrees Celsius, or 22 degrees Celsius (room temp.) to the oxygen consumption of dried peas as it also underwent the same temperatures of ten and 22 degrees Celsius. I hypothesized that the germinating peas would consume…

    Introduction: Based on preliminary research, the hypothesis of the present study was that at temperatures higher or lower than 40 degrees Celsius fermentation is inhibited. Alcoholic fermentation is used in food production such as brewing, winemaking, and baking (Campbell). Thus optimizing fermentation and understanding the effect of various environmental factors can have important economic and social benefits. The production of CO2 is being assessed to show the rate of fermentation at certain…

    After doing some research, I looked at a number of issues effecting the environment which are caused by humanity in its relations with the earth and life on it. There were discussions conducted and utilized readings which were assigned to different topics involving the environment. The main focus evolved around climate change; the causes and possible outcomes. However there are more problems on determining the ethics of our solutions than actual solutions. What are we doing to protect the…

    In every experiment there are constraints and requirements. Specifically in our Solar Oven Project we had budget, material, and performance constraints. The inside chamber, where the biscuit is cooked, must have a volume of 1000 cm3. In addition to that, the length of the window and the depth of the inside chamber must be at least 5 cm. The window must also be a square. The inside cooking chamber must be able to easily insert and remove the biscuit and hold the biscuit in place so when the oven…
