In cosmology, the equation of state of a perfect fluid is characterized by a dimensionless number w, equal to the ratio of its pressure p to its energy density ρ: . It is closely related to the thermodynamic equation of state and ideal gas law.

What is viral equation of state?
the Equation of State is a thermodynamic equation describing the state of matter under a given set of physical conditions. It is a constitutive equation which provides a mathematical relationship between two or more state functions associated with the matter, such as its temperature, pressure, volume, or internal energy. there are two common types of this equations of state. the first one is Cubic E.O.S, which has a triple root for its solution and the second one is the Viral Equation of State which depends mainly on a long series of constants that depend on Tr and Pr and other materials properties.

What is the chemical equation of radium and oxygen?
Radium has an oxidation state of +2, Oxygen has an oxidation state of -2.....so it'll look like this Skeleton equation: Ra + O2 --> RaO.... Balanced equation 2Ra + O2---> 2RaO

How do you calculate vapour pressure from an EOS?
Use the Equation of State (EOS) in combination with the Antoine's Equation to determine vapor pressure.
What is difference between real gas and perfect gas?
Equation of state of gas is an equation that links the important variable that defines the state of the gaseous system. The equation must accurately integrate the variable so that it could be used to determine the state of the system through measurement of some of the variables. An example of the EoS is the perfect gas equation of state: PV=nRT This equation is useful for gas at low pressure because it assume that the gas molecules does not occupies space and do not interact with each other. Different equation of state has been proposed to capture the system more accurately. Another rexample is the van der Waal equation of state: P = nRT/(V-bn) -a(n2/V) where a and b are van der Waals constant with a representing the volume occupy by the molecules and a as representing the intermolecular interaction among the molecules.
