The Ideal Gas Law is written as ( PV = nRT ). This law suggests that gases behave in a perfect way. However, in real life, especially in engineering, things don’t always match up. Here are some important reasons why:
High Pressure: When gas is under high pressure, it gets squished. This causes the forces between gas particles to matter more. Because of this, gases don’t act exactly as the law predicts. To help with this, scientists use the Van der Waals equation, which includes special adjustments for volume and pressure.
Low Temperature: When temperatures drop, gas particles have less energy and can stick together more. This can cause gas to turn into a liquid sooner than what the Ideal Gas Law suggests. This can create problems for designs that depend on gas staying as a vapor.
Gases with Strong Attractions: Some gases, like carbon dioxide (CO₂) and ammonia (NH₃), have strong forces pulling their particles together. Because of this, the Ideal Gas Law doesn't work well for these gases.
Mixing Gases: When gases are mixed together, the total pressure isn't always the sum of the pressures from each gas due to different interactions. This makes predictions tougher.
To deal with these issues, engineers can use the Van der Waals equation or other models that focus on real gases to get a better idea of how gases will behave in different situations.
