Question

Почему не изменяется температура кристаллических тел при плавлении или отвердевании

Answer 1

Потому что кристалические молекулы смыкаются,не давая проникнуть чему-либо,вродь

Answer 2

Why doesn't the temperature of crystalline solids change during melting or solidification?

When a crystalline solid undergoes melting or solidification, the temperature remains constant until the phase transition is complete. This phenomenon is known as the latent heat of fusion or solidification. The temperature at which this occurs is called the melting point or freezing point of the substance.

During melting, the energy supplied to the solid is used to overcome the forces of attraction between the particles, allowing them to move more freely and transition into the liquid phase. This energy is known as the latent heat of fusion. Similarly, during solidification, the energy is released as the particles lose their freedom of movement and form a regular lattice structure characteristic of a solid.

The reason the temperature remains constant during these phase transitions is due to the absorption or release of latent heat. The energy being supplied or released is used to break or form intermolecular bonds, rather than increasing or decreasing the kinetic energy of the particles. As a result, the temperature remains constant until the phase transition is complete.

In summary, the temperature of crystalline solids does not change during melting or solidification because the energy supplied or released is used to break or form intermolecular bonds, rather than increasing or decreasing the kinetic energy of the particles.
