To convert the boiling point of refrigerant HCFC-22 from degrees Celsius to degrees Fahrenheit, we use the formula:
[tex]\[ F = C \times \frac{9}{5} + 32 \][/tex]
where [tex]\( F \)[/tex] is the temperature in degrees Fahrenheit and [tex]\( C \)[/tex] is the temperature in degrees Celsius.
Given:
[tex]\[ C = -40.6 \][/tex]
Substituting [tex]\( C \)[/tex] into the formula:
[tex]\[ F = -40.6 \times \frac{9}{5} + 32 \][/tex]
[tex]\[ F = -40.6 \times 1.8 + 32 \][/tex]
[tex]\[ F = -73.08 + 32 \][/tex]
[tex]\[ F \approx -41.08 \][/tex]
So, the boiling point of HCFC-22 in degrees Fahrenheit is approximately [tex]\(-41.08^\circ F\)[/tex].
