✦ Synopsis

Through detailed analysis of themost accurate Regnault-Pfaundlerformula and thecurrent approximate formulae for cooling correction used in bomb calorimetry, two new formulae have been developed. These require much simpler procedure to determine the relevant parameters and yet possess accuracy comparable to formulae of the same type. Also, on the basis of an equation, due to Mott, relating the rate of temperature fall v in the calorimeter vessel and the relevant temperature differences, a method is proposed for evaluating v by calculation instead of actual observation. This enables the customary preliminary and after periods to be dispensed with. By incorporating the new formulae with this calculation method for v. the determination of calorific value with the isothermal calorimeter can be performed as simply as with the adiabatic calorimeter.
