Understanding the definitions of heat and work A mixture of gaseous reactants is put into a cylinder, where a chemical reaction turns them into gaseous products. The cylinder has a piston that moves in or out, as necessary, to keep a constant pressure on the mixture of 1 atm. The cylinder is also submerged in a large insulated water bath. (See sketch at night.) From previous experiments, this chemical reaction is known to absorb 239. LJ of energy. The temperature...

An insulated piston-cylinder device contains 0.1m3 of air (ideal gas) at 400 kPa and 25℃. A paddle wheel within the cylinder is rotated until 15 kJ of work is done on the air while the pressure is held constant. Assuming the kinetic and potential energies are negligible and the gas constant and specific heat of air are ? = 0.287 kJ kg∙K and ?? = 1.005 kJ kg∙K . Tasks: ( a ) Determine the mass of air inside the...
