Introduction: Alcohols are used in everyday life and as a result they are of great interest to chemists, specifically in regards to energy output. Energy output is extremely important when it comes to classifying a compound’s uses. For example, a compound with an explosive energy output can be implemented as a fuel for cars or other vehicles. This is the very reason that accurate information about the heat and/or energy output of alcohols are in high demand in many industries. Fuels release…

Omar Lab 1 Cover letter Dear Dr. …………., This experiment aims at determining carbon (IV) dioxide bubble and dew points as a single component by the use of PVT stimulator at four distinctive temperatures. Besides, it determines the increasing of pressure effect on the carbon (IV) dioxide two-phase envelope. The starting pressure was set at two thousand psi with a (±0.1 psi precision. The beginning volume for carbon (IV) dioxide gas was set at zero while the liquid carbon (IV) dioxide at 14.7 cc…

Single Component Study Using PVT Simulator Lab Report 1 Section W03 Nicholas Wells ID: 800098661 September 8, 2016 Cover Letter Dr. Ebrahim Fathi, The purpose of the first lab was familiarize the class with phase behavior using a PVT Simulator. PVT is an acronym for Pressure, Temperature, and Volume. The PVT Simulator is a program on the computer called PVTLab. Phase behavior experiments can be done using an actual PVT apparatus but they are very expensive and the experiments would take hours…

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…

INTRODUCTION The trends in physical properties of organic compounds such as boiling points and melting points can be deducted from their structures, including size (molecular weight, surface area), shape and functional groups. These factors significantly influence the strength of the intermolecular 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…

Purpose The purpose of this experiment is to confirm the functional relationship of Boyle’s law through the use of a manometer. The two parts of this experiment will determine the number of moles of oxygen and the second part will determine the number of moles of nitrogen, that will lead to determine the value of R by measuring P, V, and T. Theory/Principles A physical law such as Boyle’s law states that P, the exerted fixed mass of gas at a constant temperature and V, the volume have a…

Symmetry Writing Exercise Paragraph 1 The research paper written by J. Haines, O. Cambon and S. Hull 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…

INTRODUCTION: Exercise 3.1 - Osmosis: Toward the start of lab, we found out about diffusion which can happen as active transport or passive transport. Diffusion is known as delivering a net development of solute particles from locales of higher focus to districts of lower concentration. Active transport is the development of an atom over the plasma layer. Active transport is when atoms move against their focus slopes. We discovered that dynamic transport requires vitality, and the motivation…
