Combined Gas Law
The combined gas law is a combination of Boyle’s law, Charles’s law, and Gay-Lussac’s law. It relates the pressure, volume, and temperature of a gas under different conditions.
The combined gas law equation is:
P1V 1/T 1= P 2V 2/T 2
where:
- P is the pressure of the gas
- V is the volume of the gas
- T is the temperature of the gas
The combined gas law can be used to solve a variety of problems involving gases. For example, it can be used to calculate the pressure of a gas when its volume and temperature change, or to calculate the volume of a gas when its pressure and temperature change.
Worksheet Problems
Here is a set of combined gas law worksheet problems with varying difficulty levels:
- A gas has a volume of 1.0 L at a pressure of 1.0 atm and a temperature of 273 K. What is the volume of the gas when the pressure is increased to 2.0 atm and the temperature is decreased to 223 K?
- A gas has a pressure of 2.0 atm, a volume of 2.0 L, and a temperature of 300 K. What is the pressure of the gas when the volume is decreased to 1.0 L and the temperature is increased to 400 K?
- A gas has a volume of 1.0 L, a pressure of 1.0 atm, and a temperature of 273 K. What is the temperature of the gas when the volume is increased to 2.0 L and the pressure is decreased to 0.5 atm?
Answer Key
Here is a comprehensive answer key for the worksheet problems:
| Problem | Solution | Explanation |
|---|---|---|
| 1 | 0.5 L | Using the combined gas law equation, we have: |
| P1V1/T1 = P2V2/T2 | ||
| 1.0 atm x 1.0 L / 273 K = 2.0 atm x V2 / 223 K | ||
| V2 = 0.5 L | ||
| 2 | 4.0 atm | Using the combined gas law equation, we have: |
| P1V1/T1 = P2V2/T2 | ||
| 2.0 atm x 2.0 L / 300 K = P2 x 1.0 L / 400 K | ||
| P2 = 4.0 atm | ||
| 3 | 546 K | Using the combined gas law equation, we have: |
| P1V1/T1 = P2V2/T2 | ||
| 1.0 atm x 1.0 L / 273 K = 0.5 atm x 2.0 L / T2 | ||
| T2 = 546 K |
