Chemical System

Definition

A chemical system refers to a specific portion of matter in a given space that is being studied for changes in its chemical reactions or properties.

Analogy

Think of a chemical system like the stage of a theater. The actors (molecules) are interacting with each other, and we're only interested in what's happening on the stage (the system), not what's going on backstage or in the audience.

Closed System: This is a type of system where matter cannot be exchanged with the surroundings but energy can. It's like having an aquarium with a lid - nothing gets in or out, but light (energy) can still pass through.

Open System: An open system allows both matter and energy to be exchanged with its surroundings. Imagine it as an open bowl of soup - heat can escape, and you can add more ingredients into it.

Isolated System: In this type of system, neither matter nor energy can be exchanged with the surroundings. It's like having your lunch packed tightly inside an insulated lunch box - nothing gets in or out until you open it up!
