Try a sample
Two gases begin on opposite sides of a container. After a barrier is removed, their particles mix through random motion. What is this mixing called?
- Cutting
- Diffusion
- Freezing
- Magnetic attraction
See the answer & why
Diffusion
Diffusion is spreading and mixing through particle motion.
A little hint: Use the particle arrangement described; a model represents behavior without being a picture of every particle.
