Question

why ideal gas equation is called equation o state? ​

Answer 1

Answer:

Ideal gas equation is called equation of state because it is the combination of two gas laws.

Explanation:

Ideal gas law = PV/T=constant.

Derivation --

let two pressures p¹ and p²

let two volumes v¹ and vx.

therefore according to Boyle's law,

vx=p¹v¹/p².

let two temperature t¹ and t².

let two volumes v² and vx.

therefore, according to Charles' Law,

vx=v² t¹/t²

Therefore,

v²t¹/t²=vx=p1v¹/p²

Therefore, p¹v¹/t¹=p²v²/t²

showing pv/t = constant

Answer 2

Answer:

Assuming an equilibrium state, the three properties needed to completely define the state of a system are pressure (P), volume (V), and temperature (T). Hence, the definition: An Equation of State (EOS) is a semi-empirical functional relationship between pressure, volume and temperature of a pure substance. Ideal gas equation is also called equation of states because it is relation between four variables and describes the state of any gas. Hence option B is correct answer.
