Question

What is Gas Laws? Or Define gas kaws ans give a few examples of descriptions on points.

Answer 1

Gas Laws:-

• The laws which relate the properties of gasses like pressure, volume, mass and temperature are called gas laws.

⇝All gas laws are based on experimental data.

━━━━━━━━━━━━━━━━

Boyle's Law:-

• At constant temperature, the volume of a given mass of a gas is inversely proportional to it's pressure.

$\red{\boxed{\bold{\large{V \: \propto \: \dfrac{1}{P}}}}}$

Or,

• At constant temperature for a given mass of gas, the product if it's volume and pressure is constant.

$\red{\boxed{\bold{\large{P_{1}V_{1} \: =P_{2}V_{2}}}}}$

━━━━━━━━━━━━━━━━

Charle's Law:-

• At constant pressure the volume of a given mass of a gas is directly proportional to it's temperature.

$\red{\boxed{\bold{\large{V \: \propto \: T}}}}$

━━━━━━━━━━━━━━━━

Gay-Lussac's Law:-

• For a gas at constant volume, pressure of the gas is directly proportional to it's temperature.

$\red{\boxed{\bold{\large{P \: \propto \: T}}}}$

━━━━━━━━━━━━━━━━

Avogadro's Law:-

• For a given gas at constant temperature and pressure, equal volumes will contain equal number or molecules or moles.

$\red{\boxed{\bold{\large{ \dfrac{V1}{n1} = \dfrac{V2}{n2} }}}}$

Need to know:-

Ideal gas equation :

• PV = nRT

Where:-

• P = Pressure
• V = Volume
• n = Number of moles
• R = Gas constant
• T = Temperature.
