An ideal gas is in equilibrium at initial state with temperature t=137oc, pressure p = 0.75pa and volume v = 0.75 m3. if there is a change in state in which the gas undergoes an isothermal process to a final state of equilibrium during which the volume is doubled. calculate the temperature and pressure of the gas at this final state.

your answer is c

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.
