suppose a sample of 1 mole of a diatomic ideal gas at 1 atm and 20 degrees C is ADIABATICALLY expanded to 5 times its original volume. What is the final pressure of the gas ?(assume rotational modes are fully active and vibrational modes are frozen out)
What is the final temperature of the gas in C?
what is the change in internal energy of the gas?
how much work did the gas do on the environment?
how much heat is absorbed by the gas during the expansion?
