## Important Topics for NCERT Chemistry Exemplar Solutions Class 11 Chapter 5 – States of Matter

Intermolecular Forces

The forces that facilitate connections between molecules, containing the forces of like or dislike which act between molecules and other types of neighbouring elements. For example, atoms or ions.

Boyle’s Law

Boyle’s Law describes that the volume of a certain mass of gas is directly proportional to the absolute temperature at continuous pressure. It is stated as PV = k where P refers to pressure, V is volume and k is a constant term. This law is also known as the Boyle-Mariotte law or Mariotte’s law.

Charles’ Law

Charles’s Law describes that the volume of a certain mass of gas is inversely proportional to the absolute pressure at a continuous temperature. It is stated as V/T = k where V refers to the volume of gas, T is the temperature of the gas, and k is a constant term. The temperature is measured on a Kelvin scale. This law is also known as the law of volumes.

Gay Lussac’s Law

Gay-Lussac’s Law describes that the pressure of a certain mass of gas varies directly with the absolute temperature of the gas when the volume is kept continuous.

Avogadro’s law describes that the equal volumes of all gases, at a similar temperature and pressure, have a similar number of molecules.

Viscosity

Viscosity refers to the resistance of a fluid to a change in shape, or movement of neighbouring servings relative to one another. It represents opposition to flow. The reciprocal of the viscosity is known as the fluidity. For example, Molasses has a larger viscosity than water.
