Physics

n = 4.67 mol of Hydrogen gas is initially at T = 345.0 Ktemperature and p_i = 3.02Ã—10⁵ Pa pressure.The gas is then reversibly and isothermally compressed until itspressure reaches p_f = 6.72Ã—10⁵ Pa. What isthe volume of the gas at the end of the compression process?
How much work did the external force perform?
How much heat did the gas emit?
How much entropy did the gas emit?
What would be the temperature of the gas, if the gas was allowedto adiabatically expand back to its original pressure?
