atmosphere are perfectly mixed‚ so pure‚ dry air behaves as if it is a single gas with very definite physical properties. Nitrogen gas is a molecule consisting of two nitrogen atoms (N2). It does not easily react with other substances. Soil bacteria do take up very small amounts of nitrogen‚ which can be used by plants‚ but otherwise nitrogen is largely “filler‚” adding inert bulk to the atmosphere. In contrast‚ oxygen gas (O2) is chemically very active‚ combining readily with other elements in the

DISCUSSION Part A: The effect of pressure head on maximum flow of gas for different size orifices For the orifices having different sizes but located at same level‚ the orifice 1‚ 2‚ 3 and 4 are having sizes of 0.5‚ 0.38‚ 0.28 and 0.1cm respectively. Based on the result obtained‚ the graph of Pressure Head vs. maximum flow rate for Orifice having different size but at the same level at a pressure for 1‚ 2 and 3 bar was plotted. Based on the graph obtained for all three different pressures‚ it

everything around us (anything that takes up space – living or nonliving) and is most commonly in three states (solid‚ liquid and gas). By examining the objects‚ students learn that the book is a solid (in the form of molecules is tightly bound)‚ the water is a liquid (the molecules are close together and moving loosely past one another)‚ and the balloon contains a gas. Students manipulate the oobleck and learn that it does not follow one state of matter (it is a Non-Newtonian substance). By observing

Overview The Bhopal disaster‚ also referred to as the Bhopal gas tragedy‚ was a gas leak incident in India‚ considered the world’s worst industrial disaster.It occurred on the night of 2–3 December 1984 at the Union Carbide India Limited (UCIL) pesticide plant in Bhopal‚ Madhya Pradesh. Over 500‚000 people were exposed to methyl isocyanate gas and other chemicals. The toxic substance made its way in and around the shantytowns located near the plant.Estimates vary on the death toll.

Jacques Charles invented a couple of different things. Some of these are the valve line‚ the appendix‚ the nacelle‚ and the hydrometer. The valve line is a device that releases gas from a balloon and would ensure an easy descent. The appendix is a tube that lets expanded gas out of the balloon. The appendix will prevent the balloon from bursting from its internal pressure. The nacelle is a wicker basket that is held onto a hot air balloon by ropes. And finally a hydrometer

Even though the diffused gas had reached the top of the jar some amount of liquid bromine remained at the bottom of the container. Results: Liquid bromine changed to gas and diffused until the jar was completely filled with gaseous bromine. Discussion: Diffusion is one of the fundamental processes by which material moves. Diffusion is a consequence
