The heat capacity fo methane is 4.298R, can be assumed to be independent of T. Methane may be assumed to follow the ideas gas law. a) 1.7mols of methane are contained in a piton/cylinder device at 0.1Mpa and 20C. It undergoes a reversible isothermal compression to 0.5MPa. What are deltaH, deltaU, Q,W for the process? b)Methane flows at steady-State through an adiabatic compressor. The inlet state is 0.1Mpa and 20C. The gas is compressed at 0.7Mpa and 188C. How much work must the compressor perform (Kj/mol)?
