Class 11 Physics Chapter 13 – Concepts Covered

Boyle’s Law: According to this law, the volume (V) of a fixed mass of a gas is inversely proportional to the pressure (P) of that gas, given that the temperature of the gas is kept constant.

V ∝ 1/P or PV = constant

Charle’s Law: The volume (V) of a given mass of a gas is directly proportional to the temperature of the gas, given that the pressure of the gas remains constant.

V ∝ T or VT = constant
V₁T₂= V₂T₂

Gay Lussac’s Law: The pressure P of a given mass of gas is directly proportional to its absolute temperature T, given that the volume V of the gas remains constant.

P ∝ T or PT = constant
P₁T₁= P₂T₂

Equation of State of An Ideal Gas: The relation between pressure, volume, and absolute temperature of a gas is known as its equation of state.

PV = nRT

n is the number of moles of the gas and R is the molar gas constant which is equal to 8.315 JK^-1mol^-1

Dalton’s Law of Partial Pressures states that the net pressure applied by a mixture of non-interacting gases is equivalent to the sum of their pressures.

P = P₁ + P₂ + ------- + P_n
