Question

derive the relation between three coefficient of thermal expansion​

Answer 1

Answer:

heating of a body is accompanied by an increase in size of the body.this phenomenon is thermal expansion.

there are three types of thermal expansion:

linear expansion  :coefficient is alpha

areal expansion:coefficient is beta

cubical expansion:coefficient is gama

Explanation:

beta=2 alpha=alpha=beta/2.........[1]

gama=3 alpha=alpha= gama/3.......[2]

from 1 and 2

beta/2=gama/3=gama/3=beta/2=alpha

alpha:beta:gama=1:2:3
