The enthalpy of a system is given by the equation H=U+PV where U is the internal energy, P=pressure, and V=volume. In addition, the internal energy, U=Q+W where Q is the heat and W is the work. Suppose we want to find the rate of change in the enthalpy at constant pressure of 1.75 atm, what is the value when heat is absorbed by the system at a rate of 55 J/s and work is done by the system at a rate of 200 J/s when the change of volume is rated at 76 x 10^-5 m^3/s? 1. What is the change in heat with respect to time? 2. What is the change in internal energy of the system with respect to time? 3. What is the change in enthalpy of the system with respect to time?
