Question

a gas at pressure above the critical pressure does not separate into two phases when it is cooled at constant pressure​

Answer 1

Explanation:

regions that represent the different phases exhibited by a substance (Figure 11.6.1 ). Each region corresponds to the range of combinations of temperature and pressure over which that phase is stable. The combination of high pressure and low temperature (upper left of Figure 11.6.1 ) corresponds to the solid phase, whereas the gas phase is favored at high temperature and low pressure (lower right). The combination of high temperature and high pressure (upper right) corresponds
