Explanation

Intermolecular forces (between molecules) are much weaker than intramolecular (binding) forces that hold atoms together in a molecule.

Examples: hydrogen bonds, van der Waals forces vs. covalent or ionic bonds.

Explanation

Filtration is the process of separating solids from liquids using a filter medium.

It is commonly used in laboratories, water purification, and chemical processes.

Explanation

Explanation

Evaporation is the process where liquid turns into gas at temperatures below its boiling point.

It occurs at the surface of the liquid.

It is influenced by factors like temperature and surface area.

Explanation

Liquids take the shape of their container, meaning they have no definite shape, but they maintain a constant volume regardless of the container they are in. 

Explanation

Mustard gas (sulfur mustard) is a viscous liquid at room temperature with a relatively high boiling point.

It was used as a chemical warfare agent because it evaporates slowly, making it effective over time.

Explanation

Noble gases have complete outer electron shells, making them chemically stable.

Because of this stable configuration, they generally show valency = 0.

Explanation

Pure water has extremely low ionization, producing very few H^+ and OH^- ions.

Since electrical conductivity requires free ions, pure water is almost a non-conductor.

Explanation

The reaction at the anode is called oxidation.

In electrochemical cells, the anode is where oxidation occurs, meaning the substance loses electrons.

This contrasts with the cathode, where reduction (gain of electrons) takes place.

Explanation

1 Volt (V) is equal to 1 Joule per Coulomb (JC^-1).
