Diagram A is the best representation of gas molecules in a closed container.
To determine the arrangement of gas molecules in a container, we need know about gas molecules.
What is gas?
- Gas or vapour is a state of a substance in which the molecules are separated by maximum distance among all other states (solid, liquid).
- It's always kept in a closed container.
How do gas molecules behave?
- In gas, the molecules are free from each other. They have not made any kind bond between them.
- Also, the molecules move freely and takes the whole space of the container.
Thus, we can conclude that as the gas molecules spread out easily throughout the space of the container, so diagram A is the best representation of gas molecules in a closed container.
