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.

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

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
