Generally, $\frac{dQ}{dt} = \text{rate in} â \text{rate out}$ Typically, the resulting differential equations are either separable or first-order linear DEs. Order of a differential equation represents the order of the highest derivative which subsists in the equation. In applications, the functions usually denote the physical quantities whereas the derivatives denote their rates of alteration, and the differential equation represents a relationship between the two. In mathematics a Partial Differential Equation (PDE) is a differential equation that contains unknown multivariable functions and their partial derivatives (A special Case are ordinary differential equations. This model even explains the effect of pressure i.e at these conditions the adsorbate's partial pressure, , is related to the volume of it, V, adsorbed onto a solid adsorbent. Another interesting application of differential equations is the modelling of events that are exponentially growing but has a certain limit. Differential equations are of basic importance in molecular biology mathematics because many biological laws and relations appear mathematically in the form of a differential equation. Dear Colleagues, The study of oscillatory phenomena is an important part of the theory of differential equations. l n m m 0 = k t. when t = 1 , m = 1 2 m 0 gives k = â ln 2. l n m m 0 = â 2 ( l n 2) t. Now when the sheet loses 99% of the moisture, the moisture present is 1%. As a consequence of diversified creation of life around us, multitude of operations, innumerable activities, therefore, differential equations, to model the countless physical situations are attainable. According to the model, adsorption and desorption are reversible processes. One of the fundamental examples of differential equations in daily life application is the Malthusian Law of population growth.
