Saturated steam at 100°C is heated to 400°C. Use the steam tables to determine

(a) The required heat input (J/s) if a continuous stream flowing at 100 kg/s undergoes the process at constant pressure and

(b) The required heat input (J) if 100 kg undergoes the process in a constant-volume container. What is the physical significance of the difference between the numerical values of these two quantities?
