Energetics Practical 2: To Determine the Enthalpy Change of a Reaction Background Calcium Carbonate‚ CaCO₃‚ decomposes with heat to form CaO and CO₂. The objective of this practical was to determine the enthalpy change for this reaction by using an indirect method based upon the foundation of Hess’ Law. Both calcium oxide and calcium carbonate react readily with 2 mol/dm3. The reaction can be demonstrated as so: CaCO₃ (s) -> CaO(s) + CO₂ (g) Results: Raw Data Calcium Carbonate Mass of CaCO₃

to describe how the human body reacts to changes and keeps itself within certain parameters to ensure that it can function correctly. These reactions include a range of responses‚ from the release of hormones to regulate internal imbalances to sweating to lower body temperature. Homeostasis is the process used by the body to maintain a stable internal environment. Either negative feedback or positive feedback can be used in homeostasis. In negative feedback‚ the body changes an internal condition

What is exercise physiology? Exercise physiology is the science that describes‚ explains and uses the body’s response to exercise and adaption to exercise to maximise human physical potential. Exercise physiology is very important in touch because the amount of physical activity our body can tolerate‚ the better we will play for the longest amount of time. ATP/CP system is used by the body to produce ATP quickly in the absence of oxygen. High intensity activities lasting for less than 10 seconds

spectrometer. [2] It is being used widely in the field of physics‚ materials science‚ chemistry‚ biochemistry‚ and molecular biology[3] as it is an optical instrument that measure the amount of light absorbed by the solutes in the solution‚ thus measuring the absorbance of a solution. The mechanism behind this theory is based on the reference on the visible light spectrum. Different compounds absorb different wavelengths of light and appear to be the colour that it’s reflected which can be observed

Practical Ethics H.Narayanan‚ EE Department IIT Bombay‚ Mumbai (Text of a lecture delivered on 16th Oct 2012) A dilemma faced by young people‚ usually at the stage when they leave home for the first time‚ is that rules that they have lived by thus far seem questionable. On the one hand the impulses that tempt and torment them seem natural while on the other‚ breaking rules that the parents have taught them in their childhood seems very wrong. Further‚ those who break their shackles are in danger

Measuring the effectiveness of human computer interaction - HCI - can be complex as it involves many influencing factors‚ some of which are determined on an emotional level (making it subjective rather than quantitative). The effectiveness of HCI relates to the usability of a computer system by a human. For a computer to be effective‚ HCI levels must be high. In simple terms‚ a computer that is difficult to use is not a good computer. Indicators of the effectiveness of HCI There are a

Physiology plays a major role in the way the body functions. In football the body has to adapt to the intensity of the game as it varies from low to high. A footballer would mainly use their aerobic energy system due to constant and consistent exercise. It is suggested that footballers use 90% of their aerobic metabolism (Mcmillan et al 2004). Yet they would also use their anaerobic energy when displaying skills such as striking as it uses a short burst of energy. The aerobic capacity of a footballer
