Problem 6: A rigid tank of volume V = 0.015 m³ contains carbon monoxide at a temperature of To = 21° C and a pressure of Po = 9.00 × 105 Pa. This molecule should be treated as a diatomic ideal gas with active vibrational modes. Part (a) In this model, how many degrees of freedom does each molecule of carbon monoxide have? 7 ✓ Correct! Part (b) The temperature of the gas increases by 10° C. Select the process that has occurred from the choices below. This is an isochoric process. ✓ Correct! Part (c) Calculate the pressure of the gas in pascal at this increased temperature. P=9.3*105 P = 9.300 × 105 ✓ Correct! Part (d) Calculate the change to the internal energy of the gas in joules. AU = 290.51 AS = 66.90 Part (e) Calculate the change in the entropy of the gas in joules per kelvin. AS = 66.90 * Attempts Remain
