# Gas Laws Practice Worksheets
## Boyle's Law Problems

2. A sample of nitrogen has a volume of 10 L at 0.80 atm. What pressure is required to compress it to 6
L?
3. A gas at 3.0 atm is compressed from 9 L to 3 L. What is the new pressure?
## Charles' Law Problems
4. A gas occupies 2.5 L at 300 K. What is the volume at 360 K?
5. A balloon has a volume of 1.2 L at 280 K. What temperature is required for it to reach 2.0 L?
6. A gas expands from 3 L to 4.5 L when heated from 250 K. What is the final temperature?
## Gay-Lussac's Law Problems
7. A gas is at 1.5 atm and 290 K. What is the pressure at 350 K?
8. A container at 2.0 atm is heated from 250 K to 500 K. What is the new pressure?
9. A gas at 3.0 atm drops in temperature from 400 K to 200 K. What is its final pressure?
## Solutions
### Boyle’s Law Solutions
1. P1V1 = P2V2 → 1.2×4.0 = 2.4×V2 → V2 = 2.0 L
2. 0.80×10 = P2×6 → P2 = 1.33 atm
3. 3.0×9 = P2×3 → P2 = 9.0 atm
### Charles’ Law Solutions
4. V1/T1 = V2/T2 → 2.5/300 = V2/360 → V2 = 3.0 L
5. 1.2/280 = 2.0/T2 → T2 = 467 K
6. 3/250 = 4.5/T2 → T2 = 375 K
### Gay-Lussac’s Law Solutions
7. P1/T1 = P2/T2 → 1.5/290 = P2/350 → P2 = 1.81 atm
8. 2.0/250 = P2/500 → P2 = 4.0 atm
9. 3.0/400 = P2/200 → P2 = 1.5 atm
