if the boiling point of a substance is 176 ° F and the freezing point is 42° F what is the inequality the substance can stay between in which it remains liquid?

Answer 1

Hey there,

In order for it to stay a liquid, the substance has to be above 42 degrees and below 176 degrees. Therefore,

the inequality would be 42<x<176 degrees. You can't use a less than or equal to sign for these since they can't be equal to those values. Hope this helps!
