The world needs a new source of energy, an unspillable source.

chemistry help? thanks.?

Electrical power plants and ships commonly use steam to drive turbines, producing mechanical energy from the pressure of the system. The rotating turbine is connected to a generator that produces electricity. Steam enters a turbine at a high temperature and pressure and exits, still a gas, at a lower temperature and pressure. Determine the final pressure of steam that is converted from 10.0kL at 600kPa and 150C to 18.0kL at 110C.
