a) Methane gas allowed to expand from a volume of 3.2 L to a volume of 8.5 L. During the course of the process, 640 J of thermal energy was transferred from the surroundings to the methane gas. Based on the same expansion: i) How much work has been done if the gas expands against a vacuum with explanation? ii) How much work has been done if the gas expands against a pressure of 2.3 atm? iii) What is the change in the internal energy of the system with proper reason?
