Considering one mole of monatomic ideal gas in the initial state of 300 K and 1 atm for each of the transformations indicated below, the gas is:

Heat to 400 K at constant pressure, Heats a constant volume up to 500 K, Expand isothermally until the pressure drops to 1/3 of its initial value, It expands isothermally against a constant external pressure of 1/6 of the initial pressure, until the gas pressure reaches the value of the external pressure, It expands adiabatically until the gas pressure reached is the initial pressure. Determine:

Q, W, H, U and s If it does not close the cycle, what process would you propose? Draw the processes performed on a Pv diagram

Note: For calculations use the international system of units
