WebIf samples of helium and xenon gas, with very different molecular masses, are at the same temperature, the molecules have the same average kinetic energy. The internal energy of a thermodynamic system is the sum of the mechanical energies of all of the molecules in it. We can now give an equation for the internal energy of a monatomic ideal gas. WebJan 17, 2024 · In a thermodynamic process with 2 moles of gas, 30 J of heat is released and 22 J of work is done on the gas. Given that the initial internal energy of the sample was 20 J. What will be the final internal energy ? (A) 72J (B) 32J (C) 28J (D) 12J thermodynamics class-11 1 Answer +1 vote answered Jan 17, 2024 by Nakul01 (37.0k points)

WebQuestion: A piston cylinder assembly containing 0.7 kg Helium gas at 101 kPa with an initial volume of 5.27 m3 undergoes a thermodynamics cycle containing three processes as follows: Process 1-2 Isobaric compression until its volume becomes half the original volume Process 2-3 Polytropic expansion that obeys PV^n = C where n = -1.2 until original … WebIn summary, the second law of thermodynamics dictates that the entropy change of a closed system must be greater than zero during an irreversible proces. During a reversible is othermal process, the entropy of helium gas in a piston-cylinder device will always increase, because the entropy exchange lctween the gas and the surroundings must ... how do you treat dmdd
