Question

A spherical bubble inside water has radius R . Take the pressure inside the bubble and the water pressure to be p₀. The bubble now gets compressed radially in an adiabatic manner so that its radius becomes (R −α). For ≪ the magnitude of the work done in the process is given by (4πp₀Rα² )X, where is a constant and γ =C_p/C_v = 41/30. The value of is______.

Answer 1

Correct answer is 2.05

{for small change (ΔP)_avg<P> arithmetic mean}
