Temperature

characterized by semi-arid climate with little precipitation and extreme temperature variation. Typically, deserts may see less than 250 mm of precipitation annually and extreme temperatures may range between 0°C and 50°C.(3). Hot deserts occur mostly into belts in the northern and southern hemisphere, between 15° and 35° latitude. (Ref 4) Characteristics of semi-arid and arid hot deserts include extreme summer temperatures, and…

science fair project is questioning whether or not mints really make one's mouth cold. To test this the theory, the project will include a glass of lukewarm with mints added in every few minutes. How will adding mints in a glass of room temperature water affect the temperature of water? Why does it feel like mints cool down one's mouth? According to David McKemy, a neurobiologist at USC Dornsife, a protein called TRPM8 that is found in all cold sensing nerve fibers that triggers an electrical…

In addition, higher SGR of V. parahaemolyticus was observed as the temperature increases. The MPD values of V. parahaemolyticus varies from the lowest 7.00 to the highest 8.91, regardless of the type of V. parahaemolyticus strain at the 3 different temperatures. The differences in LT values were increased as the temperature was increased. At 20 °C, the shortest LT was observed with the (tlh+) strain, followed by (tdh+/trh+), the mixture, the (tdh+) and the (trh+). At 25°C the strains likely kept…

highest at room temperature is not supported by the data, although there was error in the data. The data from the lab showed rate of oxygen consumed to be the highest at 1.5 degrees Celsius with a rate of .0124ppt/min/g. At room temperature there was a rate of .0077ppt/min/g, and at the hottest temperature (95.6 degrees Celsius) a rate of -.0131ppt/min/g, meaning that oxygen was not consumed but actually increased in concentration in the biochamber. In reality, room temperature should have had…

is a glow-stick that is the same type of glow-stick to the others but is not affected by the different water temperatures. The reason for not allowing the glow-stick to be placed in the different water temperatures is because the experiment is testing the glow-sticks at different water temperatures, so it is reasonable to have the standard of comparison to be a glow-stick at the temperature all the other glow sticks have originally started at. Materials: There are three beakers, water, beaker…

the beakers, dissolve all the salt to make salt water, add one ice cube to each beaker, adding a drop of food color to each of the beaker, wait for the observation, count the time required for the ice to melt with a chronometer, and measure the temperature…

The resting metabolic rate, RMR, is influenced by psychological stress, free-fat mass, body temperature, and body surface area. Body temperature influences RMR through increasing its rate as the temperature increases because since heat is energy the overall amount of energy is increased in order to maintain said temperature increase, which in turn increases RMR. Resting metabolic rate is influenced by psychological stress because since the amount of stress…

aims to understand how Iron III phosphate (FEPO4) behaves under high temperatures and at which temperature would we start to observe structural transition of Iron III phosphate. As found by the researchers, the temperature where one is able to witness a structural change of Iron III phosphate, a transition from α-β would be at the temperature of 980K. As the researchers have highlighted, there have been substantial high temperatures experiments done on isotopes (AIPO4) and Quartz (SiO4). However…

results found in the collated table supports the hypothesis, however, it was not as accurate as expected. From observation of the collated results, it can be seen that the greatest froth volume is found at 30oC, rather than the predicted optimum temperature of 39oC. Errors within the individual group results, concluded that the both 10oC and 20oC were wrong due to the vast froth volumes. For a smaller amount of catalase, this would result in a smaller froth volume, conversely, with a greater…

Sample one had 50mL of distilled water at a temperature of 22°C, it took the spinach disks an average time of 17:06 minutes before reaching the top. This occurred because the enzymes in the spinach disks were functioning around an optimum temperature for photosynthesis and the production of oxygen. Sample two had 50mL of distilled water at a temperature of 10°C, the spinach disks had no movement at all. Sample three had 50mL of distilled water at a temperature of 60°C, the spinach disks did not…
