2. Who Was Robert Boyle?
Before we delve into the intricacies of Boyle's Law, let's briefly introduce the man behind this essential scientific principle. Robert Boyle, an influential Irish chemist and physicist in the 17th century, was not only a pioneer of modern chemistry but also a prominent figure in natural philosophy. His meticulous experiments and groundbreaking work laid the foundation for Boyle's Law.
3. What is Boyle's Law?
Boyle's Law, in essence, states that "the pressure of a given amount of gas is inversely proportional to its volume when the temperature and the amount of gas are held constant." This means that as the volume of a gas increases, its pressure decreases, and vice versa. But how can we mathematically represent this principle?
4. Mathematical Representation of Boyle's Law
P ∝ (1/V)
P = k*(1/V) ⇒ PV = k
Boyle's Law can be expressed mathematically as(P1 . V1 = P2 .V2), where:
(P1) represents the initial pressure of the gas.
(V1) represents the initial volume of the gas.
(P2) represents the final pressure of the gas.
(V2) represents the final volume of the gas.
This equation signifies that the product of the initial pressure and volume of a gas is equal to the product of the final pressure and volume when the temperature remains constant.
5. The Inverse Relationship: Pressure vs. Volume
Boyle's Law illustrates an inverse relationship between pressure and volume. As you decrease the volume of a gas while keeping the temperature constant, the pressure increases. Conversely, if you increase the volume, the pressure decreases. This concept is best understood through graphical representations of pressure-volume relationships.
P ∝ (1/V)
P = k*(1/V) ⇒ PV = k
When plotting the relationship between the pressure exerted by the gas (P) on the vertical Y-axis and the reciprocal of the volume occupied by the gas (1/V) on the horizontal X-axis, it becomes evident that a linear or straight-line graph is generated.

6. How Does Boyle’s Law Work?
- Boyle’s Law operates on the principle that the pressure and volume of a gas exhibit an inverse relationship. When the temperature remains constant, an increase in volume results in a decrease in pressure, and conversely, a decrease in volume leads to an increase in pressure.
7. What happens to pressure if the volume is doubled?
- For a fixed mass of gas at a constant temperature, pressure is inversely proportional to volume. If the volume is doubled, the pressure is halved.
