Hello, Faizan Here
Can anyone show ne how to derive the formula of specific heat capacity pls.??? Also i need the derivation of the formula of magnification power of a lens??? Thanks in advance to anyone who helps me.

FUNKER

to obtain specific heat capacity of an ideal gas at constant pressure =
Q/(n*dT) where Q is amount of heat , n is numba of moles of gas and dT is change in temp. You can use pV=nRT to find the temp at different stages where R =8.314;
hope that helps
peace
