A certain mechanical device with a mechanism similar to a piston contains a certain amount of gas. Upon compression from 30 L to 10 L, the gas released 450 J of heat. Experiment shows that the external pressure of the mechanical device is given by:Pext = AsinV + BcosV + CsinhV + DcoshVWhere:A = 100B = 80C = 1x10⁻²⁵D = 5x10⁻³⁰sin = sine functioncos = cosine functionsinh = hyperbolic sine functioncosh = hyperbolic cosine functionV = in litersPext = in atmDetermine the change in internal energy of the system in kilojoules.TIP: usually, expressions involving trigonometric functions are in radians.
