An ideal gas is initiaily at temperature T and volumoeV. lts volume is increased by Delta V due to an increase in temperature Delta T, pressure remaining constant. The quantity k = AV//(V Delta T) varies with temperature as: |
|
Answer» <P> At const. pressure. `Pdv =nRdT` `(dV)/(dT) =(NR)/(P)` `AB.P =(nRT)/(V)` `therefore (dV)/(dT) =(nR)/(nRT) cdot V` `rArr (1)/(V) cdot (dV)/(dT) =(1)/(T)` `rArr k=(1)/(T) rArr k prop (1)/(T)` THUS, CORRECT choice is (c ). |
