Thermal Expansion

The increase in the volume of a material when particle in motion increases.When this happens Kinetic energy increases.The opposite is known as Thermal contraction.

The meaning of Thermal Expansion

what is Thermal Contraction

thermal contraction is when the kinetic energy of the particles decrease and occupy less volume.

note: Kinetic energy in particles means the faster or slower the motion of the particles is.

the difference between the both

VS

Thermal Expansion

Thermal contraction

• Has MORE kinetic energy
• Occupies more volume (it expands)
• overall thermal expansion has more motion than the thermal contraction

• Has less kinetic energy
• occupies a less amount of volume
• overall thermal contraction has less motion than the thermal expansion

ThankYou!
