A 120 cm^3 box contains helium at a pressure of 1.80 atm and a temperature of 120 ∘C. It is placed in thermal contact with a 220 cm^3 box containing argon at a pressure of 4.20 atm and a temperature of 390 ∘C.
a.)What is the initial thermal energy of each gas? Enter your answers numerically separated by a comma.
b.)What is the final thermal energy of each gas?Enter your answers numerically separated by a comma.
c.)How much heat energy is transferred, and in which direction?
d.)From He to Ar or from Ar to He?
e.)What is the final temperature?
f.)What is the final pressure in each box? Enter your answers numerically separated by a comma.
For part A I kept getting the answer Ei(He),Ei(Ar)= 32.8, 127.7 J
This isn't correct, so any help would be very appreciated!
