Final answer:
The saturation temperature of CFC-500 is the temperature at which it changes from a liquid to a gas at a given pressure.
Step-by-step explanation:
The saturation temperature of CFC-500 at 90 Psig can be determined by referring to a pressure-temperature chart for the substance. However, since specific data about CFC-500 is not provided, I am unable to give you the exact saturation temperature.
CFC-500 is a type of refrigerant, and its saturation temperature is the temperature at which it changes from a liquid to a gas at a given pressure. The saturation temperature of a substance varies depending on the pressure it is subjected to.
