Q. One mole of an ideal gas at 27 °C is expanded isothermally from an initial pressure of 3.00 atm to a final pressure of 1.00 atm in two ways. (a) reversible, and (b) against a constant external pressure of 1.00 atm. Calculate q, w, ΔU, ΔH, ΔSsys, ΔSsurr, ΔStotal for each path. [C_(V,m)=3/2 R]
Q. A speedboat mocing at 34.0 m/s approaches a no-wake buoy marker 100m ahead. the pilot slow the boat with a constant acceleration of -3.65 m/s2 by reducing the throttle. how long does it take to reach the boat?
