thermal expansivity मीनिंग इन हिंदी

In its liquid form, pure water also displays negative thermal expansivity below 3.984 �C.
Influences of fast neutron radiation on electrical and thermal conductivity, thermal expansivity, dimensional stability, on the storage of internal energy ( Wigner energy ), and on many other properties have been observed many times and in many countries after the first results emerged from the X-10 reactor in 1944.
He is also sometimes credited, rightfully according to many modern scholars, with being the first to publish convincing evidence that, in Gay-Lussac s words, " All gases have the same mean thermal expansivity at constant pressure over the same range of temperature ", or when heated, a wide variety of gases respond in the same predictable way.
More specifically, considering the non-additivity of the volumes of the components in this type of solutions, how does the thermal expansion coefficient of a component or of the mixture ( as a function of the activity coeffcient ? i ( ? i ) ) differ from the ideal case where is supposed to be a weighted sum of thermal expansivity of components without activity coefficients which are 1 in this case ?-- talk ) 17 : 15, 11 July 2016 ( UTC)
