Research on gas masks I researched gas masks. I found out about: The history Gas masks were issued to all British civilians at the start of World War 2. In Britain fear was around because the British government thought that the Nazi German bombers would drop poison gas bombs. At the start of the war some citizens had not been issued with a gas mask. In a government document "If war should come" the explanation for this was that district leaders might have decided to keep gas masks in storage

Ideal Gas Law: The ideal gas law is the equation of state of a hypothetical ideal gas. It obeys Boyle’s Law and Charles Law. Ideal Gas Law Formula : General Gas Equation: PV = nRT Pressure(P) = nRT / V Volume(V) = nRT / P Temperature(T) = PV / nR Moles of Gas(n) = PV / RT where‚ P = pressure‚ V = volume‚ n = moles of gas‚ T = temperature‚ R = 8.314 J K-1 mol-1‚ ideal gas constant. Ideal Gas Law Example: Case 1: Find the volume from the 0.250 moles gas at 200kpa and 300K temperature

Gas Laws Lab Introduction: The four basic physical properties of a gas sample are pressure‚ volume‚ temperature‚ and number of moles. The volume simply indicates the volume of the container since a gas will take up all space available to it. The temperature indicates the average kinetic energy of the gas particles. For gases‚ the temperature must be converted to the Kelvin unit. The pressure of the gas indicates the number of collisions with each other and the wall of the container. The number

Data and Conclusions: The purpose of this experiment was to learn how to use distillation and gas chromatography to separate and identify different compounds from a given mixture. There are several kinds of distillation methods. However‚ the method that we used in this experiment was fractional distillation. This method is used when trying to separate two different volatile compounds whose boiling points differ by 40-50°C or more. If the boiling points are too close‚ this method

Gas exchange is the movement of respiratory gases across a membrane. It is the delivery of oxygen to the body‚ and the elimination of carbon dioxide from the body .The reason why gas exchange takes place because oxygen is one of the most essential requirements of life‚ without which organisms on Earth would not survive. Living organisms generate energy from food through the process of respiration. This allows humans and other organisms to perform their daily tasks. Oxygen is used in mitochondria

Types of Cement Rapid Hardening Portland Cement Rapid Hardening Portland Cement(RHPC) is a special purpose cement used in concrete to achieve a higher rate of early strength development‚ compared to using Normal Cement. The improved early performance of RHPC is achieved principally through increased product fineness. Typical applications of RHPC include precast concrete production‚ concrete masonry‚ urgent repair work and cold weather concreting. Extra Rapid Hardening Cement An extra rapid

distinction between three types of legitimate domination: traditional (where ’legitimacy is claimed for it and believed in by sanctity of age-old rules and powers’)‚ charismatic (based on `devotion to the exceptional sanctity‚ heroism or exemplary character of an individual person’)‚ and legal-rational domination (which rests on ’a belief in the legality of enacted rules and the right of those elevated to authority under such rules to issue commands’). It is‚ of course‚ this third type that is a central
