Thermal Properties Of Matter

The study of thermal properties of matter involves understanding how substances change states through processes like melting and solidification. Melting is characterized by a constant temperature where thermal energy is absorbed without a change in temperature, known as the melting point.

Melting And Solidification

Solidification
The change of state between a liquid to a solid
Reverse process of melting
Melting
Melting occurs at a definite or constant tmeperature

During the change of state, temperature does not change even though thermal energy is absorbed.

This temperature is called melting point

occurs at a constant temperature

The change of state between solid to liquid

Internal Energy

What is Internal Energy?
Internal Energy comprises of two components:

Potential Energy

The amount of energy stored is dependent on the force between the particles and the distance between the particles

Potential Component is due to the compressing and stretching of the interatomic and intermolecular bonds as the particle vibrate.

Kinetic Energy

In liquids and gases, kinetic energy is due to movement instead of vibration

Vibration of particles is also related to temperature

Eg. higher the temperature, more vigorous the vibration

Kinetic Component is due to vibration of particles

The total energy of the particle is called Internal Energy
Particles in a solid held together by strong interatomic or intermolecular bonds, and vibrate in a fix position.
