Question

Ivan heats at constant pressure 2.10 moles of a diatomic gas starting at 300K. For this gas, the        molecules vibrate above 500K.   A total of 20,000J of heat is put into the gas during this process.

a) Clearly show that the final temperature of the gas is TF = 599K.

b) How many joules of the (20,000J of) heat went into increasing the kinetic energy of translation?

c) How many joules of the heat went into increasing the energies associated with vibration?

d) How many joules of the heat went into increasing the kinetic energy of rotation?

e) What is the total of your energies in parts b), c), and d)?

f) If there is a difference between 20,000J and your answer in part e), what kind of energy did that difference become?
