THE CONDENSATION AND SUBLIMATION OF CO2 WITH H2O: CARBONIC ACID ON MARS

The condensation and sublimation of mixtures of CO2 with H2O have been studied at temperatures between 80 and 230 K. Evidence is presented for the existence of metastable, solid-phase H2O.CO2. With near-equilibrium condensation the measured heats of sublimation of CO2 and H2O are independent of the...

Description
Summary:The condensation and sublimation of mixtures of CO2 with H2O have been studied at temperatures between 80 and 230 K. Evidence is presented for the existence of metastable, solid-phase H2O.CO2. With near-equilibrium condensation the measured heats of sublimation of CO2 and H2O are independent of the mixing ratio; it is therefore unlikely that CO2 and H2O will co-precipitate on Mars at temperatures appreciably higher than required for CO2 to condense alone.
