Question 2 (1 point) Gas in a piston-cylinder apparatus is heated with 6.276 kJ while simultaneously decreasing its volume from 1.500 L to 0.500 L at a constant pressure of 1.013 bar. Calculate the total energy change, AU, (in kJ) for this process. Pay careful attention to units. +6.266 +6.377 0-6.377 O 0(the work and heat contributions cancel out) -6.266

A piston-cylinder assembly contains propane, initially at 27 °C,
1 bar, and a volume of 0.2 m3 . The propane undergoes a process to
a final pressure of 6 bar, during which the pressure-volume
relationship is pV1.1 = constant. For the propane, evaluate the
work and heat transfer, each in kJ. Kinetic and potential energy
effects can be ignored.

A combustion reaction releases 345 KJ of heat and produces gas that does 29 Kcal of work on the lid of the container. What is the change of energy? 29kcal = 121.336 KJ Since the reaction releases 345 KJ and then does 121.336 KJ of work on the lid of a container, I thought both would be negative, but the correct answer in our practice quiz says they should both be positive. I got -466 KJ and it says it...
