Question

Which of the following temperatures is the coldest? A) 5 degrees B)0 degrees C) -15 degrees D) -7 degrees

Answer 1

It’s c -15 degrees because it it has below O which is below freezing

Answer 2

Well, it's most likely choice-C, but ONLY if the choices are all measured on the same temperature scale.  

For example . . .

--> 5 degrees Fahrenheit is colder than 0 degrees Celsius

--> 0 degrees Fahrenheit and 5 degrees Fahrenheit are both colder than -7 degrees Celsius, AND they're both colder than -15 degrees Celsius
