But in other countries, such as England, you'll get the weather forecast in degrees Celsius. Recipes will advise you to bake a pie at 205ºC and not 400ºF. In fact, the Celsius scale is the most commonly used temperature scale in the world. This week, we have special cause to wonder about the history of this scale, because November 27 is the 300th anniversary of the birthday of the man who invented it. Anders Celsius was born in Sweden in 1701. His parents didn't know that their son's work would one
Down Fat Aim: To investigate the effect of temperature on an enzyme’s (lipase) ability to break down fat. Hypothesis: The graph below shows the rate increasing as the enzymes get closer to their optimum temperature (around 35 degrees Celsius) from room temperature. The enzyme particles are moving quicker because the temperature increases so more collisions and reactions occur between the enzymes and the substrate molecules. After this the graph shows the rate decreasing as the enzymes
The confused flour beetle, Tribolium Confusum is an organism that is approximately 4.35mm in body length and is made up of three sections, the prognathous head, rounded abdomen and a straight sided thorax, which are flat, shiny, elongated and rigid, reddish brown (Stuart M Bennett 2003). This beetle consists of two segmented antennas at the front of its body along with two small dark colored notched eyes, separated by more than three eye diameters, which allow the beetle to identify small disturbances
of respiration. The cold water bath should slow the respiration down in all three respirometers. II. Materials and Procedures. For this experiment we have prepared to water baths. One bath is ice water, around 10 degrees Celsius, the other warm, around 25 degrees Celsius. Both water bath...
have an effect on the daphnia, I intend to carry out the following experiment. The experiment will involve measuring the cardiac activity of the daphnia at different temperatures, ranging from very cold (approx. 5 degrees Celsius) to quite warm (approx. 40 degrees Celsius). · A selection of similar sized/age Daphnia will be taken. · A variety of different temperatures of water will be set up, these temperatures will be kept constant whilst the daphnia are submersed in them. The temperatures
the name that comes to your mind? Is it Albert Einstein, Isaac Newton, or Charles Darwin? Not me, I think about Anders Celsius. The reason why is because of his greatest invention, which was the Celsius thermometer. Anders had other great inventions and observations also, like the observations of the aurora borealis. He also built the Uppsala Observatory. Anders Celsius was a great inventor and will be remembered as one of the best scientist in the world. He was born on November 27, 1701 in
Thermal protection is a method of detecting over-temperature conditions and disconnecting the electrical power. This usually used to prevent fires or damage to electronics power supplies and equipment which may arise from the high temperatures. Temperature in power supplies rises due to both environmental factors as well as heat generated by the components themselves. There is heat from semiconductors such as transistors, ICs, switching devices, from transformers, inductors and resistors. The amount
lower temperature. This slope becomes apparent Conclusions Over the observed fifty seconds, there was a consistency among the temperatures. Without a calculated percent error, we are able to assume the average temperature was twenty-six degrees Celsius. There are factors that could have caused error to arise in our data collection. One factor could be that the temperature of the room was not consistent throughout the room. Another factor may have been the performance of the thermometer. The grasp
their shells and whenever fresh hot water was added to the hot treatment to keep the temperature stable, the snails would get agitated and begin to crawl up the walls of the glass bowl. Generally, the 30 degrees Celsius temperature increased the locomotion of the snails, and the 5 degrees Celsius restricted its ability to move. In a study, it was concluded that muscle contraction is inhibited by low temperatures, therefore we predicted that the C. nemoralis would move much quicker when exposed to high
The graph of rate of reaction against temperature did show that the 2 factors were proportional, but only up to a point. After 60 degrees Celsius the next temperature measurement showed that the reaction did not occur. I believe that this is because at some point between 60 to 80 degrees Celsius the Trypsin enzyme became denatured, (this is where the heat distorts the enzyme in such a way that stops it from functioning). While it is said that rate
had mixed a sample was taken from the test tube using a pipette and mixed with the droplets of iodine in one of the chambers of the spotting tile. The experiment was repeated many times for different temperatures ranging from 20 degrees Celsius to 60 Celsius. The temperature goes up 5 degrees every time. Fair Test I will make sure that I measure the correct amounts of starch and amylase each time. I will always put 3 drops of iodine in each chamber of the spotting tile, no more, no less
the 200ml measuring cylinder measure out 150ml and pour it into the beaker. 3.Heat the water to 30 degrees Celsius and turn the Bunsen off. 4.Put the sugar cube in the beaker and turn on the the timer. 5.Stir the water 3 times in one minute. 6.After it has dissolved stop the timer. 7.Record the results. 8.Repeat experiment with the values 40,50,60 and 70 degrees Celsius
A characteristic property can help identify a substance. A characteristic property will never change even when the volume of a substance is varied. A characteristic property also does not change when a substance changes state in matter. A physical property cannot identify a substance. A physical property will change when the volume of a substance is varied. It can also change when the substance changes state in matter. For example, if the volume and mass of a substance changes then the physical
is the digestive system in the human body. Enzymes called protease are produced by the stomach, the pancreas and the small intestine. These enzymes catalyse the break down of fatty acids into amino acids. These enzymes work best at 37 degrees celsius whcih is body temperature. Formalahdehyde is the enzyme which is commonly found in biological washing powder. The enzymes break down the dirt molecules in clothes into smaller dirt molecules thus making it easier for the water to clean away
his/her shower. Also, subject 1 after his/her lunch had a high temperature of 36.75 degrees Celsius. Subject 1 after lunch had a reaction time of .28 seconds. Subject 2 had a reaction time of .41 seconds before he/she took his/her shower. At the same time he/she had a temperature of 36.41 degrees Celsius. He/she had an average reaction time before bed, the lowest temperature of the day at 36.36 degrees Celsius. He/she had his/her 2nd lowest reaction time of .29 seconds then also. The point for this
causing less solar heat. Here are the temperatures of the Tundra in general: Average January temperature: -32.1 degrees Celsius Average July temperature: +4.1 degrees Celsius Temperature range: 36.2 degrees Celsius Average annual temperature: -17 degrees Celsius Lowest temperature recorded: -52.5 degrees Celsius Highest temperature recorded: +18.3 degrees Celsius After seeing these temperatures you can see the reason why barely anyone lives up there and why there is rather little
Anne Zhang 3/6/14 BSGE 7-1 Lab Report Problem Paragraph 1 Question: What is the effect of temperature on the dissolving time of an Alka-Seltzer? Alka-Seltzer is made up of baking soda, aspirin, and citric acid which gives the tablet the fizz when dropped in any temperature water. “Alka-Seltzer is a medication that works as a pain reliever and an antacid. (Antacids help neutralize stomach acidity, which can cause heartburn

Measurement Scales Paper Marketers use scales to measure the assignment of numbers to objects or persons to represent quantities to their attributes (Aaker, 2007). This includes the measurement of agreements or disagreements that relates to attitudes or objects. For example, the measurement is in two parts, the item part, and the evaluative part. It is important to understand the level of characteristics of scales such as nominal, ordinal, interval, and ratio because scales differ with respect to
