We are using V(rms) as mean velocity of the system will come out to be zero as particles are moving randomly in all the directions, So Rms (Root Mean Square) is taken.V^2(Rms) = N1 x V1^2 + N2 x V2^2 Divided by N1 + N2Here N is molecule and V is its velocity. As it is a square all velocities...
I know how to solve a homogeneous first order linear ordinary differential equation but there was something missing which i have got it now now thanks.
Thanks lychette and chestermiller sir, i know about the processes and i also know what happens when heat is taken out but i was not able to get the results by the differential equation.
