The isothermal heat conduction calorimeter: a versatile instrument for studying processes in physics, chemistry and biology
Författare
Summary, in English
An approach to teaching calorimetry is offered through practical, versatile undergraduate experiments using an isothermal heat conduction calorimeter, which measures a variety of heat changes--enthalpies of phase changes, hydration, dissolution, adsorption and desorption, and reaction--as well as the metabolic rate of living organisms. Isothermal heat-conduction calorimetry is contrasted with adiabatic calorimetry. The general design and calibration of an instrument is discussed and five student experiments are described: heat capacity of solids, enthalpy of acid-base reaction, enthalpy of vaporization, hydration of cement, and metabolic rates of insects.
