What is the relation between linear expansion coefficient (α), Areal expansion coefficient (β) and volume expansion coefficient (ϒ)

What is the relation between linear expansion coefficient (α), Areal expansion coefficient (β) and volume expansion coefficient (ϒ) Correct Answer γ = 3 × α and β = 2 × α

CONCEPT :

  • Linear expansion coefficient (α):- Change in the length of an object per unit length per degree temperature change.
  • Areal expansion coefficient (β):- Change in area of an object per unit area per degree temperature change.
  • Volumetric expansion coefficient (ϒ):- Change in volume of an object per unit volume per degree temperature change.


EXPLANATION :

Relation between α, β and ϒ is

β = 2α, ϒ = 3α

So, option B is correct

The Coordinator of an International Virtual Conference has planned six guest lectures on different areas-Cryptography, Fluid Dynamics, Big Data Analysis, Wavelet Theory, Differential Equations and Linear Algebra-to be organised only one on each day from Monday to Sunday.  Wavelet Theory should be organised immediately after Differential Equations.  Big Data Analysis should be organised on Wednesday and should not be followed by Linear Algebra.  Fluid Dynamics should be organised on Friday and there should be a gap of two days between Cryptography and Linear Algebra.  One day there will be no lecture (Saturday is not that day), and just before that day Linear Algebra will be organised. How many lectures are organised between Big Data Analysis and Wavelet Theory?
