## What is the difference between a derivative and a partial derivative?

Originally Answered: What is the difference between derivative and partial derivative? A derivative is applied to functions that have only one independent variable. A partial derivative is applied to functions that have more than one independent variable.

**What is a partial derivative in physics?**

In mathematics, a partial derivative of a function of several variables is its derivative with respect to one of those variables, with the others held constant (as opposed to the total derivative, in which all variables are allowed to vary). Partial derivatives are used in vector calculus and differential geometry.

**What is Mayers formula?**

Mayer’s formula is Cp – Cv = R. Here Cp is molar specific heat capacity of an ideal gas at constant pressure, Cv is its molar specific heat at constant volume and R is the gas constant. Specific heat capacity of a substance is defined as the heat supplied per unit mass of that substance per unit rise in temperature.
