Gas Laws

 

Gas Laws explain the behavior of an ideal gas in terms of temperature, pressure, volume.
The following are the some of the important gas laws:

• Boyle’s Law
• Charles Law
• Gay-Lussac’s Law
• Avogadro’s law
• Universal Gas Law

Boyle’s Law:

Boyle’s law states that the volume of a given mass of gas (V) is inversely proportional to its absolute pressure (P), provided the temperature of the gas (T) remains constant.

Charles Law:

According to Charles law, the volume of a given mass of gas (V) is directly proportional to its absolute temperature (T), when its pressure remains constant.

Gay-Lussac’s Law:

Gay-Lussac’s Law is also know as Amontons’ law. It states that if the volume of a given mass of a gas (V) is kept constant, then the pressure of the gas (P) is directly proportional to its absolute temperature (T).

Avogadro’s Law:

Avogadro’s law states that equal volumes of different perfect gases, at the same temperature (T) and pressure (P), contain equal number of molecules (n).

Universal Gas Law:

Combined Gas law is derived from the three gas laws Boyles law, Charles law and Gay-Lussacs law.
