Popis:	The thermal properties (thermal conductivity, thermal diffusivity, and volumetric heat capacity) of aqueous solutions of α-amino acids [R-CH(NH2)COOH]—glycine, dl-alanine, l-valine, and dl-leucine, were measured in the temperature range 20–90‡C using the hot-wire technique. The results show that the values of the thermal properties depend mainly on the amino acid concentration in the medium, the substituted alkyl group of the substances under investigation, and the temperatures. The mechanism of heat transfer is discussed, and the roles of both radiation and convection are taken into consideration.
