CALIBRATION OF TEMPERATURE AND PRESSURE SENSORS Mechanical Engineering Department Loyola Marymount University Los Angeles‚ California ABSTRACT In this laboratory experiment‚ an Omega Model PX- 236-060GV piezoresistive pressure transducer was calibrated‚ by using an AMTEK model deadweight pressure tester. For the temperature calibration an Jofra Model C-140 temperature calibrator was used. The experiment began by setting up the Jofra Model C-140 temperature calibrator‚ and taking data from

Science investigation Aim: To try to see if the temperature affects the rate in which Amylase breaks down starch into maltose. In this reaction starch is the substrate and maltose is the product. Amylase is an enzyme‚ Enzymes‚ also called catalysts‚ are in living things and there are thousand of them. Enzymes break down food by the active site on the Enzyme forming a chemical bond with a substrate and then water attacks the substrate until it is hydrolysed (split in 2). Equipment: Boiling

experiment was to determine the effect of caffeine on resting body temperature. This has to do with homeostasis‚ which is the maintenance of equilibrium. In other words‚ it is a stable body state. Homeostasis refers to the process of keeping the internal body environment in a steady state‚ when the external environment is changed (Homeostasis 2). Humans are warm-blooded creatures that generate body heat internally and maintain body temperatures at a fairly constant level – about 98.6oF (Chiras 3). In this

worn before starting the experiment. The initial room temperature should be calculated using a thermometer and a marker is used to name beakers 1 and 2. Divide the 10 test tubes into two groups and name them 1-5 in both groups. 5 different stopwatches are used to record the time for the disappearance of the blue-black color in test tubes‚ name them 1-5 also. Stopwatch 1 corresponds to test tube 1 in beaker 1 i.e. 0°C and the room temperature (that should be around 20-25°C)‚ and stopwatch 5 corresponds

I predict that as I increase the temperature‚ the distance moved by the meniscus will also increase. I believe this will happen as aerobic respiration is taking place. This is respiration involving the consumption of oxygen gas‚ producing carbon dioxide and water‚ as shown below. C6H12O6 + 6O2 --> 6CO2 + 6H2O + 36ATP This process allows energy to be produced in the form of ATP‚ Adenosine Triose Phosphate. This occurs by converting glucose into pyruvate via glycolysis. Pyruvate is then transported

butterflies need to regulate their body temperatures through thermoregulation. There are two types of ways to regulate body temperature. The first one is ectothermy. Ectothermic animals‚ or cold-blooded animals‚ rely on outside sources to heat or cool themselves. Cold-blooded animals can lie under the hot sun to heat themselves up and prepare for flight or to move around. However‚ if there is no source of heat‚ they are not able to raise their body temperature to the correct level for movement. Butterflies
