State the variables of gas law.

Explanation

### Step-by-Step Text Solution

1. **Identify the Variables**: In gas laws, there are three primary variables that are essential for understanding the behavior of gases. These variables are:
- **Volume (V)**: This refers to the space that a gas occupies.
- **Pressure (P)**: This is the force exerted by the gas particles when they collide with the walls of their container.
- **Temperature (T)**: This is a measure of the average kinetic energy of the gas particles, typically measured in Kelvin.

2. **Understanding Relationships**: The relationships between these variables can be described by several gas laws:
