consider a calorimetry experiment where 0.500 kg of lead at 100 degree is placed in 0.200 kg of water 20 degree that was contained in an aluminum calorimeter with mass of 0.400 kg and specific heat of 9.0 x 10 J

Aforce of 240.0 n causes an object to accelerate at 3.2 m/s2. what is the mass of the object?

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.
