There are two thermally insulated vessel.One with 0.025 moles of helium and other with n moles of hydrogen.Initially both the gases are at room temperature.Now equal amount of heat is supplied to both the vessels. It is found that in both the gases temperature rises by same amount. Find the number of moles of hydrogen in second vessel. |

Answer» Solution :As the gases ARC enclosed in closed vessels, the heating can be taken as isochoric heating and as HEAT supplied to both vessels are same, we have `Q=n_1C_(V_1)DELTAT=n_2=C_(V_2)DeltaT` or `0.025xx3/2RDeltaT=n5/2RDeltaT` [As for He , `C_(V_1)=3//2` R and for `H_2,C_(V_2)=5//2R` ] or `N=(0.025xx3)/5`=0.015 mole |
