The thermodynamic data for CHF Cl contained in this paper are a basis for formulations 2 of the thermodynamic behavior of this special substance. It will also contribute to the improvement of formulations for new substances.
The massic heat capacity cp = (1h/1T)p of 1,2,2,2-tetrafluoroethane (refrigerant R134a) was measured at 18 temperatures from 253 K to 523 K at pressures between 40 kPa and 30 MPa. The Joule-Thomson coefficient mJT = (1T/1p)h of this substance was measured at six temperatures from 333 K to 423 K at p
The speed of sound u is both formally independent of the amount of substance and can be measured easily with high precision (typically u/u < 1•10 -5 ). Measurement of this quantity offers a favorable route for obtaining density ρ, molar isochoric heat capacity C V,m , and molar isobaric heat capacit
## Ž . Measurements of isochoric heat capacities C for pure water and as a function of temperature along the different isochores and on the coexistence curves are reported. The measurements cover the range in temperature from 299 K to 536 K at Ž . xKNO s 0.0017969. For pure water, measurements ha
