The pressure P and volume V of a gas are connected by the relation `P V^(1/4=)`constant. The percentage increase in the pressure corresponding to a deminition of % in the volume is`1/2%`(b) `1/4%`(c) `1/8%`(d) none of these |

Answer» `pv^(1/4) = c` `p= cv^(-1/4)` `ln p = ln(cv^(-1/4))` `ln p = ln c + (-1/4)ln v` now, `(dp)/p = 0- 1/4(dv)/v` `(dp)/p = -1/4 (dv)/v` `(dp)/p = -1/4(-1/2%)` `= 1/8%` option c is correct |
