The Great Strike of 1877 Essays The Great Strike of 1877 Essay The Great Strike of 1877 Essay On July 16, 1877, in Martinsburg, West Virginia began the Great Strike of 1877.On this day railroad workers for the Baltimore Ohio Railroad were informed of a ten percent wage cut; this was the second cut like this in eight months.After one train crew abandoned their post other workers followed and the strike was under way.Strikers forbade any trains through the town of Martinsburg.Local authorities were sent out but were unsuccessful on getting the trains running again. The number of strikers grew.After sometime, the strike encompassed more then simply railroad workers.The strike involved workers from a variety of other occupations as well. The strike spread and started occurring in other parts of the country and parts of Europe. The strikers were given an image of beggars and not the image of a hard worker asking for a decent wage.This misportrayed image was given to these strikers by newspapers that were being controlled by corporations.The acts of strikers setting trains and roundhouses on fire were deeply etched in the communities head. Perhaps it gets over looked or forgotten, but it was in fact the acts of upset citizens, opposed to the railroad rates that initiated most, if not all, fires.Millions of workers which had immigrated from other countries in hopes of being better off than they were; had their hopes and inspirations of success crushed.The compression of these hopes was the work they acquired when they settled. The companies rewarded stockholders but were holding out on the workers.The companies paid a worker around a dollar a day.The employers regarded that dollar a day as enough for living for the worker and the workers family.The companies werent surprised by the strike for they set laws before the laws even existed. For example railroad owners had a law passed making it illegal to go on strike with out returning locomotives to the roundhouse (s

An Explanation of the Ideal Gas Law

An Explanation of the Ideal Gas Law The Ideal Gas Law is one of the Equations of State. Although the law describes the behavior of an ideal gas, the equation is applicable to real gases under many conditions, so it is a useful equation to learn to use. The Ideal Gas Law may be expressed as: PV NkT where:P absolute pressure in atmospheresV volume (usually in liters)n number of particles of gask Boltzmanns constant (1.38Â ·10−23 JÂ ·K−1)T temperature in Kelvin The Ideal Gas Law may be expressed in SI units where pressure is in pascals, volume is in cubic meters, N becomes n and is expressed as moles, and k is replaced by R, the Gas Constant (8.314 JÂ ·K−1Â ·mol−1): PV nRT Ideal Gases Versus Real Gases The Ideal Gas Law applies to ideal gases. An ideal gas contains molecules of a negligible size that have an average molar kinetic energy that depends only on temperature. Intermolecular forces and molecular size are not considered by the Ideal Gas Law. The Ideal Gas Law applies best to monoatomic gases at low pressure and high temperature. Lower pressure is best because then the average distance between molecules is much greater than the molecular size. Increasing the temperature helps because of the kinetic energy of the molecules increases, making the effect of intermolecular attraction less significant. Derivation of the Ideal Gas Law There are a couple of different ways to derive the Ideal as Law. A simple way to understand the law is to view it as a combination of Avogadros Law and the Combined Gas Law. The Combined Gas Law may be expressed as: PV / T C where C is a constant that is directly proportional to the quantity of the gas or number of moles of gas, n. This is Avogadros Law: C nR where R is the universal gas constant or proportionality factor. Combining the laws: PV / T nRMultiplying both sides by T yields:PV nRT Ideal Gas Law Problems Ideal vs Non-Ideal Gas ProblemsIdeal Gas Law - Constant VolumeIdeal Gas Law - Partial PressureIdeal Gas Law - Calculating MolesIdeal Gas Law - Solving for PressureIdeal Gas Law - Solving for Temperature Ideal Gas Equation for Thermodynamic Processes Process(Constant) KnownRatio P2 V2 T2 Isobaric(P) V2/V1T2/T1 P2=P1P2=P1 V2=V1(V2/V1)V2=V1(T2/T1) T2=T1(V2/V1)T2=T1(T2/T1) Isochoric(V) P2/P1T2/T1 P2=P1(P2/P1)P2=P1(T2/T1) V2=V1V2=V1 T2=T1(P2/P1)T2=T1(T2/T1) Isothermal(T) P2/P1V2/V1 P2=P1(P2/P1)P2=P1/(V2/V1) V2=V1/(P2/P1)V2=V1(V2/V1) T2=T1T2=T1 isoentropicreversibleadiabatic(entropy) P2/P1V2/V1T2/T1 P2=P1(P2/P1)P2=P1(V2/V1)−Î ³P2=P1(T2/T1)ÃŽ ³/(ÃŽ ³ − 1) V2=V1(P2/P1)(−1/ÃŽ ³)V2=V1(V2/V1)V2=V1(T2/T1)1/(1 − ÃŽ ³) T2=T1(P2/P1)(1 − 1/ÃŽ ³)T2=T1(V2/V1)(1 − ÃŽ ³)T2=T1(T2/T1) polytropic(PVn) P2/P1V2/V1T2/T1 P2=P1(P2/P1)P2=P1(V2/V1)−nP2=P1(T2/T1)n/(n − 1) V2=V1(P2/P1)(-1/n)V2=V1(V2/V1)V2=V1(T2/T1)1/(1 − n) T2=T1(P2/P1)(1 - 1/n)T2=T1(V2/V1)(1−n)T2=T1(T2/T1)
