A rigid container contains a mixture of 2 moles of a monoatomic gas with 1 mol of a polyatomic gas at a temperature of 3000 K. You then heat the mixture by supplying 39907.2 J of heat. At the end of the process, the mixture is at a temperature of 3600 K. If at 3000 K the translational as well as the 3 rotational degrees of freedom of the polyatomic gas are already activated, how many vibrational degrees of freedom does it have activated in this temperature range? (assume that the number of degrees of freedom does not change during the process)
If necessary, consider:
R = 8.314 J/mol∙K1 cal = 4.19 Jkb =1,38 x 10⁻²³ m² kg s⁻² K⁻¹
The only form of energy possessed by molecules of a monatomic ideal gas is translational kinetic energy. Using the results from the discussion of kinetic theory in Section 10.5, show that the internal energy of a monatomic ideal gas at pressure P and occupying volume V may be written as U = 3/2PV
Suppose 4.00 mol of an ideal diatomic gas, with molecular rotation but not oscillation, experienced a temperature increase of 60.0 K under constant-pressure conditions. What are (a) the energy transferred as heat Q, (b) the change Eint in internal energy of the gas, (c) the work W done by the gas, and (d) the change K in the total translational kinetic energy of the gas?
