Question

what is solidification ?​

Answer 1

★ Solidification

• The change from a liquid state to a solid state is called solidification.

→ Exothermic when solidifying.

Conditions for crystal solidification:

• The temperature reaches the freezing point.
• Continue to release heat after reaching the
• freezing point.

†

★ Definition

• The change from a liquid state to a solid state is called solidification.

Like melting, crystals have a certain solidification temperature, called the freezing point .

The heat dissipation temperature of the crystal drops, and solidification starts when it reaches the freezing point, and the temperature does not change during solidification; after the crystal is completely solidified into a solid, the temperature continues to drop. During the solidification process, the crystal is in the state of coexistence of solid and liquid.

• Amorphous crystals do not have a certain solidification temperature. Amorphous solidification process is similar to crystal, except that the temperature continues to rise during solidification, and it needs to continue to absorb heat.

Conditions for crystal solidification:

• The temperature reaches the freezing point;
• Continue to release heat after reaching the freezing point.

Melting is the opposite process of solidification.

★Phenomenon

• Water solidifies into ice.

†

★ Related knowledge

• The solidification of substances requires heat release (the heat is transferred to the outside environment, which makes the outside heat up).
• The freezing point temperature is equal to the melting point of the substance. (Both the freezing point and melting point are unique to crystalline materials and are considered to be the characteristics of crystals.)

Examples in life:

• Animal oil (lard) solidifies at room temperature
• Water freezes
• Melted sugar, chocolate solidifies when the temperature decreases
• Put the beverage into the refrigerator and freeze it into ice

★ Condensation →

• From gas to liquid: crystal dew is condensed on the lotus leaf..
• The cooling of water vapor in the air becomes visible water droplets. This phenomenon is called condensation.

Answer 2

Answer:

Hii !!!

Here is ur answer dear !

Solidification is a phenomenon in which a liquid (a disordered structure) transforms to solid ... can seriously impair the physical, chemical and mechanical properties of a cast material.

Hope it will help you !!!
