3. Like dissolve like basically works on the principle of polarity. It means the substances which possess similar chemical properties may dissolve in each other. For example, ethanol can be dissolved in water because both are polar in nature whereas non-polar molecules can be dissolved in non-polar solvents only.
4. Generally, a solute dissolves faster in a warmer solvent than it does in a cooler solvent because particles have more energy of movement. For example, if you add the same amount of sugar to a cup of hot tea and a cup of iced tea, the sugar will dissolve faster in the hot tea.

Answer:
The change from the liquid state to the solid state is called freezing. As the liquid cools, it loses thermal energy. ... For example, solid water melts at 0°C and liquid water freezes at 0°C. During freezing, the temperature of a substance remains constant while the particles in the liquid form a crystalline solid.
