Question
What is the equation of state ? Explain.
✓

Answer

The mathematical relation between the state variables (pressure, volume, temperature, amount of the substance) is called the equation of state.

In the usual notation, the equation of state for an ideal gas is PV = nRT.

For a fixed mass of gas, the number of moles, n, is constant. R is the universal gas constant. Thus, out of pressure (P), volume (V) and thermodynamic temperature (T), only two (any two) are independent.

[Hint : Part of Maxwell's equation, applied to a time varying magnetic flux, leads us to the equation $\oint \vec{E} \cdot \overline{ d l}=\frac{-d \phi_m}{d t}$, where $\vec{E}$ is the electric field induced when the magnetic flux changes at the rate of $\left.\frac{d \phi_m}{d t}\right]$
