Jessica Vandeventer 16 March 16 Static Electricity or Electrostatics Purpose/Question- The purpose of this experiment it to explore static electricity and to explore how charges effect one another. Hypothesis– Any like charges will repel each other and any unalike charges will be attracted to each other. Data Tables/ Graphs – Charging Material Pepper Salt Paper Aluminum Styrofoam Uncharged Nothing Nothing Nothing Nothing Nothing Cotton Nothing Nothing Stuck to ruler Stuck to ruler Nothing Fur…
Section 18 Comparative Effects of Cooled Environmental Temperatures on Metabolic Rate of Endotherms and Ectotherms Abstract The purpose of the experiment was to compare the metabolic rate of endothermic vetertebrates, using Mus musculus (laboratory mice), and ectothermic vertebrates, using Rana pipiens (leopard frogs), at room temperature (on average, 22.3 degrees Celsius), and at cooled body temperature (ten degrees lower than the room temperature recorded for each sample). We used a Qubits…
White light has the greatest temperature. Blue light is colder or cooler, but doesn’t absorb as much energy as the colors of red or green. Red absorbs the most light, but is hotter. Black is not in the visible spectrum of light and it absorbs all colors of light. Different colors absorb better or worse and have the most temperature ("Color Absorption and Reflection: Light into Heat Energy." Uzinggo. Web.). When a light wave is…
hypothalamus to sense normal body temperature. 9. Hypothalamus is what sensors the body temperature. 10a. The two mechanisms the body uses to cool itself are the blood vessels in the skin dilate to radiate heat and the sweat glands increase sweat production. 10b.The two mechanisms the body uses to heat itself are the blood vessels in the skin constrict, reducing heat loss and the muscles begin to shiver, generating heat. 11a. The stimulus is the hypothalamus senses that temperature is too…

Experiment #3 (Gas) a). My first hypothesis was correct. I had a hypothesis of the glove inflating when the flask was put in the hot water because I knew that gasses with more thermal energy tend to go upwards and I assumed that the heat would make the gas particles inside the bottle expand and inflate the glove when there is no more space in the bottle My second hypothesis was also correct. I had a hypothesis of the glove deflating when the flask was put in ice because I knew that when…
includes all phenomena in which an organism maintains a mean or variance of body temperature that diverts from a null expectation, defined by random use of thermal microclimates and passive exchange of heat with the environment (Akin, 2011; Kemp & Krockenberger, 2002;). In Biomimicry, through studying thermoregulation, human beings can apply nature’s techniques to architecture when designing buildings. Present temperature systems are using a lot of energy, especially to control heat and…
will be use as a major technique. By burning pieces of food, the chemical energy stored in molecular bonds is released as heat and light. The heat can be measured in units called calories. A calorie is the amount of heat required to increase the temperature of one gram of water by one degree Celsius. This process leads to the foundation of calorimetry. A calorimeter, an object…
Name: Heat stroke (hyperthermia) Overview: Hypothermia occurs when the body temperature falls below the warning level and the heart can no longer pump enough blood to make it flow through the whole body. Hypothermia occurs when the temperature of our body drops below 35 degrees Celsius or 95 degrees Fahrenheit. Causes: Hypothermia caused as a result of exposure to cold weather- without adequate protection - for an excessive time, in wherein the body is no longer able to produce the heat…
Pure water boils at 212˚ Fahrenheit (100˚ Celsius) at sea level, but water can also boil at temperatures as low as -90˚ Fahrenheit (theoretically). The reason for this phenomenon is pressure. “There is a direct correlation between pressure and temperature when it is dealing with the boiling point of water,” says Jacob Young, a mechanical designer at Blauch Brothers, Inc (Young, J.C. 2017). The pressure on Earth at sea level is 14.696 PSIA (Pounds per Square Inch Absolute). This pressure is…
