Practice Gas Laws in Chemistry
Use these practice problems to test your method after reviewing the concept explanation and worked examples.
Quick Recap
Mathematical relationships between pressure, volume, temperature, and amount of gas.
How gases behave when you squeeze them, heat them, or add more.
Example 1
easyA gas occupies 2.0\,\text{L} at 1.0\,\text{atm}. What is its volume at 3.0\,\text{atm} (constant temperature)?
Example 2
mediumUse the ideal gas law to find the volume occupied by 2.0 mol of gas at 25°\text{C} and 1.0\,\text{atm}. (R = 0.0821\,\text{L·atm/mol·K})
Example 3
easyA gas at 200\,\text{K} occupies 4.0\,\text{L}. What volume does it occupy at 400\,\text{K} (constant pressure)?
Example 4
mediumA gas occupies 2.40 L at 1.00 atm. If the pressure increases to 1.50 atm at constant temperature, what is the new volume?
