A beaker of water is placed on a hot plate, and the temperature is gradually increased. Write an equation for the rate of change of entropy with respect to time during this process, assuming the system is not in equilibrium. Use the equation to determine the rate of entropy production in the water as it is heated from 25°C to 100°C at a constant rate of 2°C/min.
