Ideal Gas Laws and Derivatives

The video tutorial explains the relationship between pressure, volume, and temperature in an ideal gas using the equation PV = 8.31 * T. It focuses on finding the rate at which the volume changes when given specific rates of change for temperature and pressure. The tutorial walks through the process of solving for the rate of volume change using calculus, specifically the chain rule, and demonstrates how to substitute given values to calculate the result.
