Question

calculate the co-efficient of cubic expansion of zinc bar​

Answer 1

Answer

◆ Answer - α = 1.111×10^-3 /K.

# Given - V0 = 0.25 m³ V = 0.30 m³ ∆T = 50 K.

# Solution - Change in volume is - ∆V = V - V0. ...

∆V = 0.05 m³ Coefficient of cubical expansion is calculated as - ∆V/V0 = 3α∆T. ...

α = 1.111×10^-3 /K. Therefore, coefficient of volume expansion will be 1.111×10^-3 /K. Thanks dear...
