Final answer:
The temperature of -89.2 degrees Celsius is equivalent to -128.56 degrees Fahrenheit when converted using the appropriate formula.
Step-by-step explanation:
To convert the temperature of -89.2 degrees Celsius to degrees Fahrenheit, we use the conversion formula: °F = (°C × 9/5) + 32. Let's do the calculation:
F = (-89.2 × 1.8) + 32
-89.2 °C × 9/5 = -160.56
F = -160.56 + 32
F ≈ -128.56
-160.56 + 32 = -128.56 °F
Therefore, the temperature of -89.2 degrees Celsius is equivalent to -128.56 degrees Fahrenheit, which is indeed well below the sublimation temperature of dry ice.
