Concept explainers
(a)
Interpretation:
Changes that happen in reducing the temperature of H2O sample from 48 oC to -4.4 oC at a constant pressure of 6.5 atm should be identified.
Concept introduction:
Phase diagram indicates the process of transformation of a particular molecule of an atom to the corresponding stages at various temperature and pressure.
At the triple point, all the stages are coexisting at the particular temperature and pressure. For water triple point appears at 0 oC and 4.58 torr lower than 1 atm.
(b)
Interpretation:
Changes happen on increasing the pressure of H2O sample from 85 atm to 226 atm at a constant temperature of 380 oC should be identified.
