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.) From previous experiments, this chemical reaction is known to absorb 132. kJ of energy. The position of the piston is monitored, and it is determined from this data that the piston does 239. kJ of work on the system during the reaction. Is the reaction exothermic or endothermic? Does the temperature of the water bath go up or down? Does the piston move in or out? Does heat flow into or out of the gas mixture? How much heat flows? Round your answer to 3 significant digits.

When air expands adiabatically (without gaining or losing heat), its pressure P and volume V are related by the equation PV14 = C where C is a constant. Suppose that at a certain instant the volume is 310 cubic centimeters and the pressure is 87 kPa and is decreasing at a rate of 8 kPa/minute. At what rate in cubic centimeters per minute is the volume increasing at this instant? cm3 min (Pa stands for Pascal it is equivalent to one Newton/(meter squared); kPa is a kiloPascal or 1000 Pascals.

Xenon and helium are both ideal, monatomic gases, but they have very different molar masses (Mxenon = 33*Mhelium). If you have 1 mole of each gas and the gases are at the same temperature, which one of the following statements is true? They both have the same internal energy, but xenon has a lower root-mean-square speed than helium. They both have the same internal energy and root-mean-square speed. They both have the same root-mean-square speed, but xenon has a greater internal energy than helium. They both have the same internal energy, but helium has a lower root-mean-square speed than xenon. They both have the same root-mean-square speed, but helium has a greater internal energy than xenon.
