Answer 1

Answer:

alpha:beta:gamma=1:2:3

♣  Alpha (α) is coefficient of linear expansion.

♦  Increase in length during expansion is called linear expansion.

It means object one side increases.

Hence α = 1

♣ Beta (β) is coefficient of superficial expansion.

♦ Increase in area during expansion is called superficial expansion.

We know area = Length × Breadth

No. of sides = 2

Hence, β = 2

♣ Gamma () is coefficient of cubical expansion.

♦ Increase in volume during expansion is called cubical expansion.

We know, volume = Length × Breadth × Height

No. of sides = 3

Hence,  = 3

So,  

alpha:beta:gamma = 1:2:3

Hence Proved!
