## Introduction

Are you having trouble with the combined gas law worksheet #1? Don't worry, we've got you covered! In this article, we will provide you with the answer key to this worksheet, along with some helpful tips and tricks to understand the concept of the combined gas law.

## What is the Combined Gas Law?

The combined gas law is a mathematical equation that relates the pressure, volume, and temperature of a gas. It is a combination of three gas laws: Boyle's law, Charles's law, and Gay-Lussac's law. The equation for the combined gas law is:

P1V1/T1 = P2V2/T2

Where P1, V1, and T1 represent the initial pressure, volume, and temperature, and P2, V2, and T2 represent the final pressure, volume, and temperature.

## Understanding the Worksheet

The combined gas law worksheet #1 is designed to test your understanding of the combined gas law equation. It consists of several problems that require you to solve for different variables in the equation. Each problem is unique and requires a different approach.

### Problem #1

The first problem on the worksheet asks you to solve for the final volume of a gas, given the initial volume, pressure, and temperature. To solve this problem, you need to rearrange the combined gas law equation to solve for V2.

V2 = (P1V1T2) / (P2T1)

Plug in the given values and solve for V2.

### Problem #2

The second problem on the worksheet asks you to solve for the initial pressure of a gas, given the final pressure, volume, and temperature. To solve this problem, you need to rearrange the combined gas law equation to solve for P1.

P1 = (P2V2T1) / (V1T2)

Plug in the given values and solve for P1.

## Answer Key

Now that you understand how to solve the problems on the combined gas law worksheet #1, here is the answer key for each problem:

### Problem #1 Answer

Given: P1 = 2 atm, V1 = 3 L, T1 = 300 K, P2 = 3 atm, T2 = 350 K Solution: V2 = (2 atm x 3 L x 350 K) / (3 atm x 300 K) = 3.5 L

### Problem #2 Answer

Given: P2 = 4 atm, V1 = 2 L, T1 = 400 K, V2 = 3 L, T2 = 450 K Solution: P1 = (4 atm x 3 L x 400 K) / (2 L x 450 K) = 5.33 atm

## Conclusion

The combined gas law can be a tricky concept to understand, but with practice and perseverance, you can master it. We hope that this article has provided you with a better understanding of the combined gas law and how to solve problems related to it. Remember to always check your work and double-check your units to avoid errors. Good luck!
