Question

For nitrogen to be a liquid, its temperature must be within 12.78 °F of –333.22 °F. Which equation can be used to find the maximum and minimum temperatures at which nitrogen is a liquid, x?

Answer 1

To be within 12.78 of -333.22 you have to add and subtract 12.78 from -333.22.
-333.22 + 12.78 =-??? = maximum temperature
-333.22 - 12.78 =??? = minimum temperature
