As long as the heat capacity is Cp=(7/2)R, one mole of gas is adiabatically compressed at 25 degrees in the piston and cylinder device to 7 bar from a state of 2 bar. This process is irreversible and requires 35% more work than the reversible insulation process from the initial state to the same final pressure state. What is the entropy change of this gas?

Which uses electromagnetic radiation to discover the properties and composition of bodies in space? space probe space station space shuttle space observatory
