Purpose: Measuring ‘g’ by dropping steel ball and Ping-Pong ball from the same height and record the time for each dropping. Then, using the equation “h=1/2g*t^2 to calculate ‘g’. For precise, we still need to find ∆g, therefore, the final data about g=gave+∆g. Method: Before we start to do the experiment, we need to find a position which can except the wind and flat ground. After that, two people as a group, one is a golfer, and another is a dropper. First, they measured use tape measure to…

The Calorimetric Determination of Enthalpy and Entropy Changes of the Thermal Decomposition of Sodium Sulphate Decahydrate Abstract Sodium sulphate decahydrate thermally decomposes to anhydrous sodium sulphate at 50⁰ C and cools to form anhydrous sodium sulphate. Using Hess's Law the enthalpy and entropy changes of this process can be determined in order to deduce the spontaneity of the reaction. The transition temperature was determined by melting the hydrated crystals at 50⁰ C and allowing…

Wallenstein, S., Quill, T., Morrison, R. S., & Cassel, C. K., 1998]. The reasons patients ask for physicians to take part in ending their life are usually if they are in extreme pain, are a burden upon family members or caregivers, or have no personal dignity left. To choose relief is not only in favor of the terminal patients, but according to polls, the rest of the public is in favor of legalizing euthanasia as well [Meier, D., Emmons, C. A., Wallenstein, S., Quill, T., Morrison, R. S., &…

Introduction Recently, there has been a rising concern regarding concussions and contact sports. Rudd, Hodge, Finley, Lewis, and Wang (2016) state that the World Medical Association claims that boxing “produces an alarming incidence of chronic brain injury” (p. 1). In addition to the prevalence of concussion in boxing, Moriarity et al. state that “amateur boxers participating in a carefully supervised competition can have cognitive impairment suggestive of a concussive injury despite the…

Chapter 2 LITERATURE SURVEY 2.1. Characteristics of Hydrogen Sulphide 2.1.1. Physical and Chemical Properties H2S is a colourless gas characterised by a rotten gas odour which is highly toxic. It is soluble in different liquids including water and alcohols. It is typically formed under deficit oxygen conditions in the presence of organic matter and sulphate compounds (WHO, 2003). Hydrogen Sulphide is also present in the atmosphere in the range of 0.0001-0.0002 ppm though it may vary with places…

Global warming, as one of the many facets of climate change is unequivocally the most pivotal climate, health, security and economic issue of the 21st century. The anthropogenic factors towards global warming are inextricable to the exponential increase in global mean temperature and its reciprocal effect on global climate systems (IPCC 2014; Keller et al. 2005; Rogelj et al. 2015a). Explicitly, international initiatives to maintain below a increase of 1.5˚C and far less than 2˚C above…
