DISSOCIATION AND SPECIFIC HEATS OF GAS HYDRATES UNDER SUBMARINE AND SUBLACUSTRINE ENVIRONMENTS
Dissociation and specific heats of synthetic methane and ethane hydrates were measured under high-pressure condition by using a heat-flow type calorimeter to understand thermodynamic properties of gas hydrates under submarine/sublacustrine environments. Ice powder was put into the sample cell and pr...
