Randall D. Knight — The Micro/Macro Connection: Problem Problem_58

A $100\text{ cm}^3$ box contains helium at a pressure of $2.0\text{ atm}$ and a temperature of $100^\circ\text{C}$. It is placed in thermal contact with a $200\text{ cm}^3$ box containing argon at a pressure of $4.0\text{ atm}$ and a temperature of $400^\circ\text{C}$. a. What is the initial thermal energy of each gas? b. What is the final thermal energy of each gas? c. How much heat energy is transferred, and in which direction? d. What is the final temperature? e. What is the final pressure in each box?
