A flask holds 2.68 kg of a monatomic ideal gas (mass number 625). If the gas changes temperature isobarically (constant pressure) from 800o C to 410o C, find the total heat added to the gas, in kJ. A positive answer means heat is added; a negative answer means heat was removed.

A flask holds 7.46 kg of a diatomic ideal gas (mass number of the gas 937). If the gas changes temperature isobarically (at constant pressure) from 319o C to 996o C, find the total work done by the gas, in kJ. A positive answer means work is done by the gas, a negative answer means work is done on the gas.

Refer to diagram 2. A flask contains 78.2 moles of a monatomic ideal gas at pressure 8.33 atm and volume 49 liters. point A on the graph. Now, the gas undergoes a cycle of three steps: - First there is an isothermal expansion to pressure 1.74 atm (point B on the graph). - Next, there is an isochoric process in which the pressure is raised to P1 (point C on the graph). - Finally, there is an isobaric compression back...

A monatomic ideal gas has an initial temperature of 381 K. This gas expands and does the same amount of work whether the expansion is adiabatic or isothermal. When the expansion is adiabatic, the final temperature of the gas is 290 K. What is the ratio of the final to the initial volume when the expansion is isothermal?

According to the Sackur–Tetrode formula, the entropy of an ideal monatomic gas grows with the mass of the atoms. Thus the entropy of a volume of argon is much greater than the same volume of helium (at the same T and p). Can you explain this in terms of information entropy?

A solid surface is in diffusive and thermal equilibrium with a monatomic ideal gas at temperature t and chemical potential μ. An adsorption site on the solid surface can be either empty (energy ε0 = 0), singly occupied (ε1 = ε), or doubly occupied (ε2 = 2ε) by an atom from the gas. If two atoms adsorb onto the same site, they also interact by a vibrational mode of frequency w. Thus, the energy of a doubly occupied site can...
