calorimetrically

Often the whole enthalpy is carried by entropy and thus measurable calorimetrically.

The glass transition temperature can be detected calorimetrically by following the change in heat capacity with change in temperature.

The fats were saponified with 5% alcoholic potassium hydroxide, extracted with HCl and ether, then measured calorimetrically.

A respected text disregards the Carathéodory's exclusion of mention of heat from the statement of the first law for closed systems, and admits heat calorimetrically defined along with work and internal energy.

Among physicists, probably the most widely used functional is the revised Perdew-Burke-Ernzerhof exchange model (a direct generalized-gradient parametrization of the free electron gas with no free parameters); however, this is not sufficiently calorimetrically accurate for gas-phase molecular calculations.
