Relating Physical Properties with Gas Laws
Various scientific laws describe the relationships between four important physical properties of gases:
✓ Volume
✓ Pressure
✓ Temperature (in Kelvin units)
✓ Amount
This section covers those various laws. Boyle’s, Charles’s, and Gay-Lussac’s laws each describe the relationship between two properties while keeping the other two properties constant; in other words, you take two properties, change one, and then see its effect on the second. Another law — a combo of Boyle’s, Charles’s, and Gay-Lussac’s individual laws — enables you to vary more than one property at a time.
That combo law doesn’t let you vary the physical property of amount. Avogadro’s Law, however, does. And there’s even an ideal gas law, which lets you take into account variations in all four physical properties.
