Calculate the coefficient of cubical expansion of a zinc bar. Whose volume is increased 0.25 from 0.35 due to the change in its temperature of 50 K.
From the data,
Volume of a zinc rod before expansion () = 0.25
Change of volume () = 0.35
Change in temperature () = 50 K
The formula to calculate the change in volume,
Substitute the known values,
Coefficient of cubical expansion of zinc rod =
