Can someone provide me some direction with this problem?

A closed, rigid, adiabatic cylinder contains one liter of hydrogen gas(H2) at 276.85 degrees celcius and pressure of 400kPa and one liter of oxygen gas (O2) at temperature 26.85 degrees celcius. The two gases are separated by a mass-less, frictionless piston through which heat is transferred until the two sides are in thermal equilibrium.
What is final temperature?
What is final pressure?
What is the final volume of helium gas?
How much work is done on or by the helium gas?-------------------------------------
H2 | O2 |
1 liter |1 liter |
400kPa | 400kPa |
276.85 degrees C |26.85 degrees C |
-------------------------------------

Yep, put it in the HW section! (points up above).

Dont worry, someone will move it for you. :wink:

Determine the initial pressure of the O2 and the number of moles of each gas. Do you know how to determine what the final temperature will be? (think heat capacity). From that determine the final volumes.

Hint: Is there a material difference between the two gases from the point of view of thermodynamics? What will the total volume be?

What is thermodynamics?

Thermodynamics is the branch of science that deals with the study of energy and its transformations, particularly in relation to heat and work.

What is a thermodynamics problem?

A thermodynamics problem is a question or scenario that involves the application of thermodynamic principles and equations to solve for unknown variables or analyze a system's behavior.

What are the laws of thermodynamics?

The laws of thermodynamics are fundamental principles that govern energy and its transformations. The first law states that energy cannot be created or destroyed, only transferred or converted. The second law states that the total entropy of a closed system always increases. The third law states that the entropy of a perfect crystal at absolute zero is zero.

What are some common types of thermodynamics problems?

Common types of thermodynamics problems include heat transfer problems, work done by or on a system, thermodynamic cycles, and phase change problems.

How do you solve a thermodynamics problem?

To solve a thermodynamics problem, you first need to identify the given information and unknown variables. Then, you can apply the appropriate thermodynamic equations, such as the first or second law of thermodynamics, to solve for the unknowns. It is also important to pay attention to units and to use the correct sign conventions for heat and work.
