Math Problem Statement
Solution
The problem is asking for the final volume of nitrogen gas, given certain conditions of a gas cylinder. Let's break it down step by step:
Known Data:
- Cylinder diameter = 7.6 cm
- Cylinder height = 30.0 cm
- Gas pressure inside the cylinder = 11.0 atm
We can assume the external pressure (at which the gas will be released) is 1 atm, as it would be at standard atmospheric conditions. The final volume is calculated using the following key steps.
Step 1: Volume of the Cylinder
The cylinder is a right circular cylinder, and the volume can be calculated using the formula for the volume of a cylinder: Where:
- is the radius (half the diameter), and
- is the height.
We can convert dimensions from cm to dm (decimeters) because the answer needs to be in liters, and 1 dm³ = 1 L.
Step 2: Use Boyle's Law for Gas Expansion
Boyle's Law relates the initial pressure and volume to the final pressure and volume under constant temperature: Where:
- (initial pressure),
- is the volume of the gas in the cylinder,
- (final pressure after the gas escapes),
- is the final volume (which we need to find).
Let me calculate this for you.### Results:
- The initial volume of nitrogen gas in the cylinder () is approximately 1.36 liters.
- After the gas is released into the plastic bag at 1 atm, the final volume () is approximately 14.97 liters.

- What would happen if the cylinder were opened in a vacuum instead of at 1 atm?
- How would the volume change if the gas inside the cylinder was at a higher pressure than 11 atm?
- How is the relationship between pressure and volume different for ideal gases versus real gases?
- What is the significance of significant digits in gas law calculations?
