A gas trapped in a piston-cylinder device is heated (as shown in (Figure 1)) from an initial temperature of 300 K. The initial load on the massless piston with an area of 0.35 m², is such that the initial pressure of the gas is 225 kPa. When the temperature of the gas reaches 600 K, the piston velocity is measured as 0.50 m/s and dE/dt is measured as 32 kW. Assume the ambient atmospheric pressure is 100 kPa. Figure 1 of 1 Part A At that instant, determine the rate of external work transfer. Express your answer to three significant figures and include appropriate units.
