Study Notes

Pressure-Volume Relationship

Definition

Boyle's Law states that, at constant temperature, the volume of a gas is inversely proportional to the pressure.

Mathematical Representation

P1V1 = P2V2

P1 and P2 are the initial and final pressures
V1 and V2 are the initial and final volumes

Key Points

As pressure increases, volume decreases
As pressure decreases, volume increases
The product of pressure and volume is constant (P1V1 = P2V2)

Graphical Representation

A graph of pressure vs. volume is a hyperbola
The curve shows that as pressure increases, volume decreases, and vice versa

Importance

Helps to understand the behavior of gases in various situations
Used in engineering, physics, and chemistry to design and optimize systems involving gases
Applies to ideal gases, which do not exist in reality, but is a useful approximation for many real-world gases
