megolvasztási

Megolvasztási is a Hungarian term that translates to "melting" or "thawing" in English. It refers to the process of a solid substance transitioning into a liquid state due to an increase in temperature. This phenomenon is a fundamental concept in physics and chemistry, describing a phase transition.

The point at which a substance undergoes melting is known as its melting point. This temperature is a characteristic property of a pure substance and remains constant under standard pressure. For example, water has a melting point of 0 degrees Celsius (32 degrees Fahrenheit) at standard atmospheric pressure. When a solid reaches its melting point, the added thermal energy is used to break the bonds holding the particles in a fixed lattice structure, allowing them to move more freely as a liquid.

The reverse process of melting is freezing or solidification, where a liquid transitions back into a solid state at its freezing point, which is typically the same temperature as the melting point. Megolvasztási is a reversible process. The term can be applied to various substances, including ice, metals, plastics, and waxes, each with its own specific melting point. Understanding megolvasztási is crucial in numerous applications, from cooking and metallurgy to material science and climate studies.
