Problem- One mole of ammonia initally at 5 \[Degree]Celcius is placed in contact with 3 moles of helium initially at 90 [Degree]Celcius. Given that the average speed c under constant volume for ammonia is 3R, if the process is carried out at constant volume, what is the final temperature of the gas mixture?
