- Abstract
- The thermodynamic functions and electrical resistivity of dense lead plasma were assessed at specific volumes ranging from 5 to 20 times greater than the standard value, under pressures between and 4.0 hPa, and with specific internal energies 3 to 18 times higher than the energy required for The recorded dependencies were later evaluated against those estimated through a classical plasma chemical model. This research aimed to uncover the effects of non-ideality on the thermodynamic characteristics and resistivity behavior of plasma. A significant finding was that the Grüneisen coefficient for this plasma varied between 0.2 and 0.4 across the entire range of states examined. Findings from the research showed that the chemical model did not accurately reflect the energy expenditure for plasma ionization and atom excitation, underestimating it by close to a factor of two, while also overestimating the temperature by a similar proportion. The inquiry additionally disclosed that in the whole spectrum of plasma states being analyzed, “pressure ionization” was a key element, and that resistivity lessened with a decrease in specific volume along isotherms.
