Suppose we are dealing with an ideal gas contained in a cylinder equipped with a movable collection. The gas undergoes different types of thermodynamic transformations while interacting with the environment. Let us consider that the gas undergoes a series of transformations under different conditions of pressure and volume. For all exercises, use the general gas law PV=nRT to perform the calculations and remember to indicate the units correctly. Exercise - Isobaric Transformation:For the initial conditions of 1 mol and 300 K, the pressure of 1 atm, determine the initial volume of the gas. Next, the gas undergoes an isobaric transformation; Calculate the final volume heated from the initial temperature of 300 K until reaching a new thermal equilibrium at 400 K.
