Calculate the coefficient of cubical expansion of a zinc bar. Whose volume is increased 0.25 m3 from 0.3 m3 due to the change in its temperature of 50K?
उत्तर
Given: αv of Zn bar
Volume of zinc bar V0 = V1 = 0.3 m3
Change in volume ∆V = V2 – V1 = 0.25 – 0.30 = 0.05 m3
Change in temperature ∆T = 50K
Coefficient of cubical expansion αv = ?
∝v = `(Δ"v")/("v"_°Δ"T"` = `0.05/(0.3xx50)` = `0.05/15`
αv = 0.0033 K-1
