Answer :
When comparing a single gas with a mixture of gases, the randomness of the arrangement of particles in the system can be considered.
A. More random:
- A mixture of gases is more random compared to a single gas. This is because in a mixture of gases, different types of gas particles are interspersed randomly throughout the container they are in.
- Each gas particle in a mixture moves independently and at different speeds, leading to a more disordered and random arrangement compared to a single gas where particles of the same type interact with each other.
Therefore, the correct answer to the question is:
A. more random.
