experience of the soldiers was beyond anything that had ever been faced before. A soldier who was attacked by poison gas says that “It seemed as if [his] lungs were gradually shutting up and [his] heart pounded away in [his] ears like the beat of a drum.

Introduction A gas is the state of matter that is characterized by having neither a fixed shape nor a fixed volume. Gases exert pressure‚ are compressible‚ have low densities and diffuse rapidly when mixed with other gases. On a microscopic level‚ the molecules (or atoms) in a gas are separated by large distances and are in constant‚ random motion. When dealing with gases‚ the Ideal Gas Law equation is the most famous equation used to relate all the factors in dealing and solving the problem

• Natural gas is an odorless‚ colorless‚ flammable gas. It is non-toxic and lighter than air. • The gas chiefly consists of methane (CH4)‚ but also contains other hydrocarbons such as ethane‚ butane‚ propane and naphtha. Oil and gas deposits in the North Sea were formed millions of years ago through the decomposition and transformation of organic matter (plant and animal remains). In its primary form‚ natural gas can be used for residential heating and cooking‚ for industrial purposes
