The latent heat of vaporization of a substance is always

What are vaporization and boiling point? Explain the process of boiling of water.

Two different liquids of the same mass are kept in two identical vessels, which are placed in a freezer that extracts heat from them at the same rate, causing each liquid to transform into a solid. The schematic figure below shows the temperature $T$ versus time $t$ plot for the two materials. We denote the specific heat in the liquid states as $C_{L 1}$ and $C_{L 2}$ for materials $1$ and $2$, respectively, and the latent heats of fusion as $L_1$ and $L_2$, respectively. Choose the correct option.

Latent heat of vaporisation of water is $22.6 \times 10^5 \ J \ kg^{-1}$. The amount of heat needed to convert $100 \ kg$ of water into vapour at $100^{\circ} C$ is

Explain the three states of matter and the process of change in states.

What is vaporization? What is normal boiling point?
