One mole of an ideal gas is initially at a state characterized by a pressure p1, a volume V1 and a temperature T1; it follows an isothermal expansion that ends by tripling the volume it occupied initially. a) Represent this process on a pV diagram. Your axes should be labelled up to scale in accordance to the statement of the question. b) Draw on the same graph an adiabatic process that may be followed by the same amount of the same gas assuming that it would have the same temperature at a certain point as your gas represented in a). c) Using the gradients of your two curves at any point (determine them); show convincingly which one is steeper.
