Consider a chemical reaction taking place in a cylindrical vessel with a movable piston in a room at 25 0C and an atmospheric pressure of 1.75 atm. It is determined that the reaction transfers 32.146 kJ of heat to the surroundings and the total energy change of the system (ΔE) is -32.965 kJ. Based on this information, determine what the final volume of the cylindrical vessel would be assuming the initial volume of the vessel was 2.50 L.

1/2 Question 3 A piston-cylinder assembly fitted with a paddle wheel contains air, initially at 38°C, 125 kPa, and a volume of 0.02 mº. Energy in the amount of 1.8 kJ is transferred to the air by the paddle wheel. The volume of the air in the piston-cylinder increases to 0.05 mº at constant pressure. If the heat transfer between the air and its surroundings can be ignored, determine (a) the mass of the air in the piston-cylinder (b) the...

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.) 1 atm pressure piston cylinder From previous experiments, this chemical reaction is known to release 360. kJ of energy water bath gases The...
