Consider a colloid for which the surface tension, entropy and surface

Consider a colloid for which the surface tension, entropy and surface area are given by the following formulae: =ap2S=bTA=pa,b and are constants Calculate the Gibb's free energy change, G, when the pressure and temperature are changed from p=0 and T=0 to the values of p and T respectively. Assuming constant volume. Answer: G=3ap3+Vp2bT2 Exercise: A suspension of oil droplets in water has an internal energy given by the equation: E=VS3A2isaconstant Calculate the surface tension of the suspension as a function of A,V and T. 18
