Calculate the coefficient of cubical expansion of a zinc bar whose volue is increased 0.25 m^(3) from 0.3 m^(3) due to change in its temperature of 50K.

Answer»

Solution :`alpha_(v)` of Zn BAR
volume of ZINCE bar `V_(0)=V_(1)=0.3 m^(3)`
Change in volume `DeltaV=V_(2)-V_(1)`
`=0.25-0.30=0.05 m^(3)`
Change in temperature `DeltaT=50 K`
Coefficient of CUBICAL expansion `alpha_(v)=?`
`alpha_(V)=(DeltaV)/(V_(0)DeltaT)=(0.05)/(0.3xx50)=(0.05)/(15)`
`alpha_(v)=0.0033 K^(-1)`
