1 altm=101.32j
A gas is confined to a cylinder under constant pressure of 3.50 atm. When the gas undergoes a particular chemical reaction, it releases 79 kJ of heat to its surroundings and expands from 22.0L to 75.2 L. Determine both AE and AH for this scenario.

1 atm pressure 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 right.) piston cylinder water bath The temperature of the water bath is monitored, and it is determined from this data that...

A frictionless-piston-cylinder device contains a liquid-vapor mixture of water at 200°C. During a constant- pressure process, 500 kJ of heat is transferred to the surrounding air at 20°C. As a result, part of the water vapor contained in the cylinder condenses. a) Draw a schematic of your system including the boundary and all relevant energy transfer. (2 pts) b) Determine the entropy change of the water, in kJ/K. (3 pts) c) For the extended system (system + surroundings), write an...
