Understanding the Gas Laws
Gas laws describe the relationships between the pressure, volume, and temperature of a gas. Understanding these relationships is critical in fields such as chemistry, physics, and engineering. The fundamental gas laws include:
- Boyle's Law: At constant temperature, the volume of a gas is inversely proportional to its pressure.
- Charles's Law: At constant pressure, the volume of a gas is directly proportional to its temperature in Kelvin.
- Avogadro's Law: At constant temperature and pressure, the volume of a gas is directly proportional to the number of moles of gas.
- Ideal Gas Law: This law combines the three previous laws into one equation: PV = nRT, where P is pressure, V is volume, n is the number of moles, R is the gas constant, and T is temperature.
