What is the Difference Between Charles Law and Gay Lussac’s Law?

🆚 Go to Comparative Table 🆚

Charles' Law and Gay-Lussac's Law are both gas laws that relate the temperature and volume of an ideal gas. However, they differ in the type of container used in their experiments.

Charles' Law, discovered by French physicist Jacques Charles, states that the volume of an ideal gas at constant pressure is directly proportional to the absolute temperature. The mathematical expression for Charles' Law is given by: $$V \alpha T$$ or $$\frac{V}{T} = k$$, where $$V$$ is the volume, $$T$$ is the temperature, and $$k$$ is a constant.

Gay-Lussac's Law, discovered by French chemist Joseph Gay-Lussac, states that the pressure of a given mass of gas varies directly with the absolute temperature when the volume is kept constant. The mathematical expression for Gay-Lussac's Law is given by: $$\frac{P}{T} = k$$, where $$P$$ is the pressure and $$T$$ is the temperature.

In summary, the main difference between Charles' Law and Gay-Lussac's Law is the type of container used in their experiments. Charles' Law uses a flexible container, while Gay-Lussac's Law uses a rigid container.

Comparative Table: Charles Law vs Gay Lussac’s Law

The main difference between Charles' Law and Gay-Lussac's Law lies in the type of container used in their experiments. Both laws relate to the properties of gases, but they were developed using different methods and containers. Here is a table summarizing the differences between the two laws:

Charles' Law Gay-Lussac's Law
States that the volume of an ideal gas at constant pressure is directly proportional to the absolute temperature. States that the pressure of a given mass of gas varies directly with the absolute temperature when the volume is kept constant.
Container used in the experiment is flexible. Container used in the experiment is rigid.
Mathematical expression: $$V \alpha T$$ or $$V/T = k$$ Mathematical expression: $$\frac{P}{T} = k$$ and $$\frac{P1}{T1} = \frac{P2}{T2}$$

Charles' Law, also known as the law of volumes, explains that the volume of an ideal gas at constant pressure is directly proportional to the absolute temperature. In contrast, Gay-Lussac's Law, also known as the law of pressure, states that the pressure of a given mass of gas varies directly with the absolute temperature when the volume is kept constant.
