An ideal gas resides in a closed cylinder (diameter is 0.5 ft) with a frictionless piston. The initial conditions are 139 mol of the ideal gas at 25oC. The piston is compressed isothermally to one third of the initial volume. The heat capacity Cv of an ideal gas is 1.5 ∙ R. (a) What is the heat interaction (kJ) for this process? (b) The piston now expands isothermally to 120% of the same initial volume. Will the heat interaction increase, decrease, or stay the same?

It is meant that like tapestry scientific theories often need to pull out since they are not relevant and often times the whole chain of theories may be pulled out.   

The haitian revolution was the result of a long struggle on the part of the slaves in the french colony of st. domingue, but was also propelled by the free mulattoes who had long faced the trials of being denoted as semi-citizens. this revolt was not unique, as there were several rebellions of its kind against the institution of plantation slavery in the caribbean, but the haitian revolution the most successful. this had a great deal to do with the influence of the french revolution, as it to inspire events in haiti. the haitian revolution would go on to serve as a model for those affected by slavery throughout the world.
