# Gay-Lussac Law Simple Definition

Discover the simple definition of Gay-Lussac’s Law, explaining the direct relationship between gas pressure and temperature. Learn about its formula, examples, case studies, and statistics.

## Understanding Gay-Lussac Law

In the world of chemistry, Gay-Lussac’s Law is a fundamental principle that helps us understand the relationship between the pressure and temperature of a gas at a constant volume. This law states that the pressure of a gas is directly proportional to its temperature when volume is held constant.

## Formula and Explanation

The formula for Gay-Lussac’s Law is P1/T1 = P2/T2, where P1 and T1 are the initial pressure and temperature, and P2 and T2 are the final pressure and temperature, respectively. This law is based on the assumption that the volume and amount of gas are kept constant.

## Example

For example, if we have a sealed container of gas at a temperature of 273K and a pressure of 1 atm, and we heat the container to 373K, according to Gay-Lussac’s Law, the pressure will increase to 2 atm.

## Case Study

In a laboratory experiment, a scientist observes the relationship between the pressure and temperature of a gas in a closed container. By varying the temperature and measuring the corresponding pressure changes, the scientist confirms the validity of Gay-Lussac’s Law.

## Statistics

According to the principles of Gay-Lussac’s Law, as temperature increases, the pressure of a gas also increases proportionally. This relationship has significant implications in various industrial processes and scientific research.
