Answer :
Final answer:
Option 2, ternary blends of refrigerants leak at uneven rates due to their differing vapor pressures, causing components to escape at varying speeds.
Explanation:
The correct statement concerning Ternary Blends of refrigerants is that they leak at uneven rates due to vapor pressures. Ternary blends are mixtures of three different refrigerants, each with its own unique set of properties, including vapor pressures. When a leak occurs, the components of the blend tend to escape at different rates based on their respective vapor pressures. High vapor pressure components would leak more rapidly than those with lower vapor pressures. Therefore, the correct answer is 2) Leak at uneven amounts due to vapor pressures.
