Question

Difference between one and three dimensional thermal expansion

Answer 1

Explanation:

There are three ways in which we categorise thermal expansion – Linear Expansion, Superficial Expansion and Cubical Expansion. These correspond to expansion in length, area and volume of a substance.

Answer 2

Answer:

• The expansion can occur in length in which case it is called Linear Expansion.
• If we take a square tile and heat it, the expansion will be on two fronts, length and breadth, here it is called Area Expansion.
• If we take a cube and heat it, all its sides expand and now the body experiences an increase in the overall volume due to this and it is called Volume Expansion.
