In this article, we will delve into the variables involved in Gay-Lussac's law and explore its significance in the context of gas behavior.

What are the Variables in Gay-Lussac's Law?

Gay-Lussac's law states that the pressure of a gas is directly proportional to its temperature, provided that the volume of the gas remains constant. This means that as the temperature of a gas increases, its pressure also increases, and vice versa. The variables involved in Gay-Lussac's law are:

• Pressure: This is the force exerted by a gas on its container or surroundings. It is measured in units of pascals (Pa) or atmospheres (atm).
• Temperature: This is a measure of the average kinetic energy of the gas molecules. It is measured in units of kelvins (K) or degrees Celsius (°C).
• Volume: This is the amount of space occupied by the gas. It is measured in units of cubic meters (m³) or liters (L).

The Correct Answer

Based on the above explanation, the correct answer to the question "What are the variables in Gay-Lussac's law?" is:

• B. Pressure, temperature, and volume

This answer is supported by the fact that Gay-Lussac's law describes the relationship between pressure, temperature, and volume of a gas.
