Question

What is meant by supercooling?

Answer 1

Hint: The freezing point is the temperature at which a liquid solidifies at normal atmospheric pressure. The freezing point is affected by several factors, including the type of molecules and intermolecular forces of attraction. We should be aware that changes in pressure can cause a substance's freezing point to rise or fall.

Complete answer:
Supercooling is defined as the process of lowering the temperature of a liquid or gas below the freezing point without allowing the gas or liquid to solidify. This is also referred to as undercooling. As the freezing process begins, the temperature of a supercooled liquid rises because the material releases its latent heat during the transition from solid to liquid state. The temperature of the substance rises as a result of the latent heat.

This process can also be classified as exothermic. It emits a significant amount of energy, raising the temperature of the surrounding environment.

Note: It should be noted that exothermic processes release energy in the form of heat or light. It has a negative overall standard enthalpy change of $\Delta H$. Water has a freezing point of $0$ degrees Celsius and exists as ice below that temperature.
