Abstract: In the framework of the thermodynamic approach to the study of macrosystems the two-parameter semi-empiric Ishikawa–Chung–Lu equation of state is considered. Using the Cardano method for the reduced form of equation of state $\tilde{P}=\tilde{P}(\tilde{V}, \tilde{T})$ the explicit form of its representations of the form $\tilde{V}=\tilde{V}(\tilde{P}, \tilde{T})$ is found.

Keywords: Ishikawa–Chung–Lu equation of state, cubicity by volume, Cardano method, reduced variables, representation of the form $\tilde{V}=\tilde{V}(\tilde{P}, \tilde{T})$.
