A sample of 0.475 mol of CO gas is held in a rigid container with a fixed volume of 1.50 m3. Initially, the gas is kept at a temperature of 575 K. Your goal is to bring the gas to a final temperature of 1575 K. At temperatures below 1150 K, the vibrational degrees of freedom of the CO molecules are frozen out. Above 1150 K, vibrational degrees of freedom are active. (a) How much heat must be added to the gas to increase its temperature from 575 K to 1575 K? Give your answer in units of Joules. (b) How much of the total heat you found in part (a) goes into increasing the translational kinetic energy
