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 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

only did poisonous gas change the experiences of war‚ but also the type of warfare. Instead of riding around on horses freely‚ soldiers had to use protection in order to evade the deadly chemicals. So‚ quickly‚ both sides developed gas masks. At first‚ soldiers held chemically treated cotton pads over their noses and mouths. Later they wore fabric face masks soaked in chemicals‚ and finally soldiers on both sides wore respirators with charcoal filters.("Technology.") These gas masks were the new
