Atmospheric thermodynamics

In April of 2011, a supercell caused 363 tornadoes to touch down in several states within a four day period. On April 27th alone, the National Oceanographic and Atmospheric Administration confirmed over 200 tornadoes touched down that ranked between F-0 and F-6 on the Fujita scale. This record breaking phenomenon resulted in the deaths of 348 people with damages estimating over $11 billion dollars. Due to the magnitude of the outbreak, National Weather Services assigned several teams to not only…

Discovering a new world below the ocean intrigues me. I have never been one for loving ocean creatures, but I do enjoy learning about the world below us. I found several facts interesting as I read the articles including: how osmosis and salinity functions, how seawater cells move, how pH affects the ocean, how decomposition works in the environment, how upwelling stirs up nutrients, and how water temperature affects organisms. One of the interesting facts discusses why osmosis and salinity…

Research Day Reflection Attending the research day in Sykes Student Union was an interesting and beneficial alternative clinical day. The day had a variety of different presentations, posters and a complimentary breakfast! To begin the day, we took a look at some research posters created by students who were enrolled in NSG 313 in the spring semester. The first poster I viewed was a literature review of the affects of breastfeeding infants with NAS. It showed that breastfeeding reduced the…

Every vehicle has a number of electrical instruments. Each one varies due to the certain make and model of the vehicle with the different variations on the particular vehicle. Take a truck for instant it has a speedometer, tachometer, and transmission temperature gauge. Due to the fact that it will be towing a heavy object and be putting stress on the motor, so it doesn’t get too hot the gauge is there to protect it. Now on a sport car your two main instruments will be the speedometer and the…

One of the main abiotic factors influencing the distribution of biomes is global atmospheric circulation. Global atmospheric circulation is the mass movement of air around earth caused by thermal energy. This mass movement of air causes three distinct atmospheric circulation cells to form, these are the Hadley Cell, Ferrel Cell and Polar Cell. Between these three cells is a dynamic area called the Intertropical Convergence Zone. Persson (2006) tells us that the Hadley Cell is caused by solar…

Quantity of heat Q = mcθ absorbed or lost by a substance 4. What does specific heat 900 J of heat needs to be supplied to 1 kg of aluminium 900 J kgof aluminium to produce a 1 °C -1 1 °C mean? temperature increase. 5. What does specific heat 4 200 J of heat needs to be supplied to 1 of water 4 200 J kg-1°C-1 kg of water to produce a 1 °C temperature mean? increase. 6. The physical When two objects of equal mass are heated at meaning of equal rates, the object with the smaller specific specific…

Burn, Baby, Burn: Comparing the burning speed of scented and unscented candles This experiment was performed to compare how quickly a scented and an unscented candle will burn. The tests were done by comparing the length that the candles will burn in 30 minutes - using unscented, rose scented and apple scented candles. Hypothesis: Unscented candles burn more quickly than scented candles. Overview: Candles Candles are a convenient way of providing light and heat when no electricity is…

The thermodynamic performance analysis of SAH with and without storage unit were conducted at Madurai City in India on two consecutive sunny days of May 29 and 30, 2015. Both the SAHs were fabricated with similar dimensions and simultaneously tested in the same location. The tests were carried out during the sunshine hours, from 10:00 AM to 06:00 PM IST. Both the collectors were inclined at an angle of 13$degree$, facing south side according to the geographic location of Madurai. The inlet…

Almost all chemical reactions involve a loss or gain of heat. This change in heat is called enthalpy. The goal of this experiment is to calculate enthalpy for three different reactions. To calculate the enthalpy of a reaction, a calorimeter is used to measure the change in heat energy from mixing different substances. The change of temperature is found by comparing the change in temperature of the system to the temperature of the surroundings. For a calorimeter, a Styrofoam cup place in a beaker…

forces of attraction present; and the nature and strength of intermolecular forces determine the variations in boilingpoints of organic compounds. The boiling point of a liquid is the temperature at which its vapor pressure equals the external or atmospheric pressure. At this temperature, every molecules of the liquid acquire enough kinetic energy to overcome the intermolecular forces attracting them to the other molecules. Therefore, boiling points…
