Explanation Consider the van der Waals equation of state. Write the van der Waals equation of state. p = R T v − b − a v 2 Here, universal gas constant is R , the temperature is T , the pressure is p , the specific volume is v , and the van der Waals constants are a , b . Write the differential of a function p = p ( v , T ) . d p = ( ∂ p ∂ T ) v d T + ( ∂ p ∂ v ) T d v d p = M d T + N d v (I) Refer Equation (I). The expression for M is as follows. M = ( ∂ p ∂ T ) v (II) Here ( ∂ p ∂ T ) v is the partial derivative of the p with respect to T at which the variable v being held constant. Substitute ( R T v − b − a v 2 ) for p in Equation (II). M = ∂ ∂ T ( R T v − b − a v 2 ) Partial differentiate with respect to temperature. M = R v − b − 0 M = R v − b Refer Equation (I). The expression for N is as follows. N = ( ∂ p d v ) T (III) Here ( ∂ p d v ) T is the partial derivative of the p with respect to v at which the variable T being held constant

Entropy

In physics, entropy means the amount of disorder or the degree of randomness associated with a thermodynamic system. The system is not self-organized when the entropy of the system is high. For instance, when a system is at an elevated temperature, its m…
