What are coupled processes?

Coupled processes are when two or more things happen together and help each other out, like best friends working as a team.

Imagine you're playing with building blocks. You have a red block that’s heavy and a blue block that’s light. If the red block pushes the blue block, they both move, but the red one moves slower, and the blue one goes faster. This is a coupled process because the movement of one affects the other, and they’re all happening at the same time.

Think of it like a seesaw in the playground. When one kid sits on one end, the other kid goes up, but if both kids jump at the same time, they both go up and down together. The movement of one kid is coupled with the movement of the other.

When you turn on a fan, it spins and makes wind. That wind helps cool your room faster. The spinning of the fan and the cooling of the room are coupled processes, they work together to make things comfortable for you.
