Question

A refrigeration system at your company uses temperature sensors fixed to read Celsius (°C) values, but the system operators in your control room understand only the Fahrenheit scale. You have been asked to make a Fahrenheit (°F) label for the high-temperature alarm, which is set to ring whenever the system temperature rises above -10°C. What Fahrenheit value should you write on the label?

a. -50°F
b. -23°F
c. -18°F
d. 14°F
e. 26°F

Answer 1

The Fahrenheit label for the high-temperature alarm set at -10°C should read 14°F, as determined by the formula for converting Celsius to Fahrenheit.

Step-by-step explanation:

To determine the Fahrenheit value for the high-temperature alarm set to ring at -10°C, you can use the formula to convert Celsius to Fahrenheit: F = (C \times 9/5) + 32 where F represents the Fahrenheit temperature and C represents the Celsius temperature.

In this case, the alarm is set to -10°C. Using the formula:

F = (-10 \times 9/5) + 32
F = (-18) + 32
F = 14°F

Therefore, you should write 14°F on the label for the high-temperature alarm.
