Practice Gas Laws in Chemistry
Use these practice problems to test your method after reviewing the concept explanation and worked examples.
Quick Recap
A set of mathematical relationships that describe how the pressure, volume, temperature, and amount (moles) of a gas are interconnected.
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?
