A copper bar of length L and area of cross section A is placed in a chamber at atmospheric pressure. If the chamber is evacuated, the percentage change in its volume will be ( compressibility of copper is 8 × 10^−12 m^2/N and 1 atm = 10^5 N/m) A copper bar of length L and area of cross section A is placed in a chamber at atmospheric pressure.
