Shock Induced Vaporization of Anhydrite CaSO_4 and Calcite CaCO_3.
We have employed the 'entropy criterion' for vaporization by shock. Derived values of the entropies of incipient and complete vaporization for anhydrite are 1.65\pm0.12 and 3.17\pm0.12 kJ(kgK)^-1...
Entropy of phase transformation text
Entropy of phase transformation text. Usual phase transformations are melting an vaporization of pure elements or compounds. A common feature for both is the constant temperature during the process.
