- Need help understanding please help Let’s assume the initial volume of the gas is 4.80 LL , the initial temperature of the gas is 29.0 °C°C , and the system is in equilibrium with an external pressure of 1.2 bar (given by the sum of a 1 bar atmospheric pressure and a 0.2 bar pressure due to a brick that rests on top of the piston). What is the final pressure of the gas? What is the final volume of the gas? What happens with the piston after you finish heating the gas? Assume you do not need to worry about the gas cooling down again because the outside of the container is at a lower temperature.
