The normal density of gold is rho and i...

The normal density of gold is `rho` and its bulk modulus is K. The increase is density of a lump of gold when a pressure P is applied uniformly on all sides is

Text Solution

Verified by Experts

`K=(P)/((dV)/(V)) rArr (dV)/(V)=(P)/(K) and rho =(M)/(V), rho +Delta rho=(M)/(V-DeltaV) rArr rho=(M)/(V-DeltaV)-(M)/(V)`
`Delta rho=(M)/(V)[(1)/(1-(DeltaB)/(V))-1] rArr Deltarho=(M)/(V)[(1)/(1-(P)/(K))-1] rArr Delta rho=(M)/(V)[(K)/(K-p)-1] rArr Delta rho =(M)/(V) [(K-K+P)/(K-P)]`
`Delta rho=(rho P)/(K-P)`
