Combined Gas Law

The combined gas law is a gas law that combines Charles's law, Boyle's law, and Gay-Lussac's law. It relates the volume, pressure, and temperature of a gas. The combined gas law is expressed by the formula:

P1V1 / T1 = P2V2 / T2

Where:

P1 = initial pressure of the gas
V1 = initial volume of the gas
T1 = initial temperature of the gas (in Kelvin)
P2 = final pressure of the gas
V2 = final volume of the gas
T2 = final temperature of the gas (in Kelvin)

Study Guide

Here are some key points to remember when studying the combined gas law:

Units: Always make sure that the temperature is in Kelvin (K) when using the combined gas law.
Proportional Relationships: Understand the direct and inverse relationships between pressure, volume, and temperature in the combined gas law.
Manipulating the Formula: Practice rearranging the formula to solve for different variables (e.g., solving for final volume or final pressure).
Real-world Applications: Explore real-world examples where the combined gas law can be applied, such as in scuba diving or in the operation of internal combustion engines.

By understanding the combined gas law and its applications, you can gain a deeper insight into the behavior of gases under different conditions.

The resources above cover the following skills:

Earth/Space Science: Students will use scientific skills and processes to explain the chemical and physical interactions (i.e., natural forces and cycles, transfer of energy) of the environment, Earth, and the universe that occur over time.

Earth History: Explain how sedimentary rock is formed periodically, embedding plant and animal remains and leaving a record of the sequence in which the plants and animals appeared and disappeared.

Explain how sedimentary rock buried deep enough may be reformed by pressure and heat and these reformed rock layers may be forced up again to become land surface and even mountains.
