Answer 1

Azeotropic refrigerants:

• Azeotropic refrigerant is a mixture of two or more substances known to boil at the same temperature.
• The substances in azeotropic refrigerants condense and evaporate together as one.
• Azeotropic mixtures are known to evaporate and condense at a constant temperature.
• Over a large temperature range, azeotropic refrigerants maintain the same composition in the liquid and vapour phases.

Example of azeotropic refrigerants:

• An example of an azeotropic refrigerant is $\mathrm{R}502$ and $\mathrm{R}407\mathrm{C}$, etc.
