Uit trees udtions 6.4 to explain why 3, assume that the avaph of an evaporating liquid comes 6.13. from the liquid itself, which then changes temperature ac cording to equation δvaph =-q m (a) explain the presence of the negative sign in this equation. (b) if 1. tainer initially containing 100.0 g of h20, what is the final temperature of the water? use c = 4.18 j/g°c and = 43.99 kj/mol at 25.0°c. the vapor pressure of h20 at 25.0°c is 23.77 torr; assume it remains constant throughout the tem- perature change of the liquid. - cat. 00 g of h20 evaporates at 25.0°c in an adiabatic con- vap

Ben(55 kg) is standing on very slippery ice when junior(25kg) bumps into him. junior was moving at a speed of 8m/s before the collision and ben and junior embrace after the collision. find the speed of ben and junior as they move across the ice after the collision .

Steam is generated in a boiler of a cogeneration plant at 10 mpa and 450°c at a steady rate of 5 kg/s. in normal operation, steam expands in a turbine to a pressure of 0.5 mpa and is then routed to the process heater, where it supplies the process heat. steam leaves the process heater as a saturated liquid and is pumped to the boiler pressure. in this mode, no steam passes through a condenser, which operates at 20 kpa. (a) determine the power produced in the turbine and the rate at which process heat is supplied in this mode. (b) determine the power produced in the turbine and the rate of process heat supplied if only 60 percent of the steam is routed to the process heater and the remainder is expanded to the condenser pressure.
