Figure represents on the log-log scale pressure (P) dependence of adiabatic compressibility (K) of two gasses. Mark the correct option/s. A. Line 1 & 2 may represent monoatomic and diatomic gas respectively.B. Line1 & 2 may represent diatomic and monoatomic gasses respectively.C. Degree of freedom for the gas represented by line 1 is more then the degree of freedom for line 2D. Degree of freedom for the gas represented by line 2 is more than the degree of freedom for line 1. |

Answer» Correct Answer - B::C Adiabatic compressibility (K) `=1//(gammaP)` Taking log In `K=-l ngammaP=-l nP-l ngamma` Let `l nK=y,l nP=x and l ngamma=c` ` Rightarrow y=-x-c` intercept on y axis is-c `=-l n gamma` `Rightarrow gamma_(2) gt gamma_(1)` Higher `gamma` means lower atomicity and lower degree of freedom. So (B) and (C) |
