A sample of dry air has an initial pressure (p1) of 1013hPa and temperature (T1) of 312K. It undergoes a process that takes it to new pressure of 600hPa with unchanged temperature (T2). Compute the mechanical work per unit mass performed by the sample under the following scenarios: a) Isochoric pressure reduction to p2 pressure followed by isobaric expansion to final state (5 points

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
