Entropy of the gases increases on mixing.
Explanation:
When two different gases are mixed together, the entropy of the system increases. This is due to the increase in the number of possible microstates or arrangements of the molecules. In the case of the hydrogen and oxygen mixture, the gases are initially separated and have different arrangements.
Entropy and Microstates:
Entropy is a measure of the disorder or randomness of a system. It is related to the number of microstates or arrangements that are available to the system. A system with more microstates has higher entropy because there are more ways for the molecules to be arranged.
Initial Arrangement:
In the given scenario, the container has a mixture of hydrogen and oxygen gases in a ratio of 4:1 by mass. This means that there are more hydrogen molecules compared to oxygen molecules in the container. Each gas has its own initial arrangement and number of microstates.
Entropy Increase on Mixing:
When the gases are mixed together, the molecules can now freely move and interact with each other. This leads to an increase in the number of possible microstates or arrangements. The molecules can now be distributed randomly throughout the container, resulting in increased disorder and randomness.
Increased Number of Microstates:
By mixing the gases, the number of microstates greatly increases. The hydrogen and oxygen molecules can now occupy more positions and have more possible arrangements. This increases the entropy of the system.
Conclusion:
In summary, when a hydrogen and oxygen mixture is mixed together, the entropy of the gases increases. This is because the number of microstates or arrangements of the molecules greatly increases, leading to an increase in disorder and randomness.
