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?

From the given conditions we can generate the maximum and minimum as:

xmax = - 333.22 °F + 12.78 °F

xmin = - 333.22 °F - 12.78 °F

Solving the equations:

xmax = - 320.44 °F

xmin = - 346 °F

Therefore, the maximum temperature is - 320.44 °F and the minimum temperature is - 346°F.
