Question

A substance has a freezing point of -20c . What is the freezing point of the substance in degrees Fahrenheit? (Round your answer to the nearest tenth.)

Answer 1

The freezing point of a substance at -20°C converts to -4°F in degrees Fahrenheit. Using the conversion formula, it is calculated and remains the same when rounded to the nearest tenth.

Step-by-step explanation:

To convert the freezing point of a substance from degrees Celsius to degrees Fahrenheit, you can use the following formula:

°F = (°C × 9/5) + 32

Given the freezing point of the substance is -20°C, let's perform the conversion:

°F = (-20 × 9/5) + 32
°F = (-36) + 32
°F = -4

Therefore, the freezing point of the substance in degrees Fahrenheit is -4°F, which when rounded to the nearest tenth is still -4.0°F.

Answer 2

F=(Cx1.8)+32. (-20x1.8)+32 -36+32=-4.

-4F is your answer.
