Question 7 Inside a container were 10 mol of pure oxygen at 3,000 keivins. This gas was conned in the container by a very heavy piston, which forced the gas to assume 3,000 itPa to mechanically balance the system. On the base of the container was a thin cylinder of graphite standing. The end of the graphite received a small spark, triggering the incomplete combustion of the graphite, which generates 111 id of heat for each mole of graphite burned. The oxygen was slowly replaced by carbon monoxide, while the plunger rose, as shown in the animation below. in the end, all the oxygen was consumed. 'i ll 1 Considering that the ideal gas constant measured 8 Jimol.K and that the process was isobaric and isothermal, answer the following questions. a) What is the increase in the volume of gas inside the container? b) Neglecting the volume of graphite consumed by the reaction, what is the amount of heat that the system lost by thermal conduction to the external environment
