Chemical Engineering Thermodynamics It is desired to bring about a certain change in the state of a system by performing work on the system under adiabatic conditions. The amount of work needed is path dependent The amount of work needed is independent of path More information is needed to conclude anything about the path dependence or otherwise of the work needed Work alone can not bring out such a change of state The amount of work needed is path dependent The amount of work needed is independent of path More information is needed to conclude anything about the path dependence or otherwise of the work needed Work alone can not bring out such a change of state ANSWER DOWNLOAD EXAMIANS APP
