Gases are one of the four fundamental states of matter. They have neither a defined shape nor volume, and they expand to fill any space available to them.
Think of gases like a group of hyperactive kids in an open playground. They run around freely, occupying all the available space without any specific pattern or order.
Molecules: These are two or more atoms bonded together. In gases, these molecules move freely and independently.
Pressure: This is the force exerted by gas per unit area on its container's walls. It's like how much those hyperactive kids push against the playground boundaries.
Volume: The amount of space that a substance or object occupies. For our playful kids (gases), this would be the entire playground they're running around in.
