Final answer:
The equation that can be used to find the maximum and minimum temperatures at which nitrogen is a liquid is |x + t| = 12.78 °F, where x is the temperature of nitrogen and t is its boiling point at atmospheric pressure.
Step-by-step explanation:
The equation that can be used to find the maximum and minimum temperatures at which nitrogen is a liquid is:
|x + t| = 12.78 °F
where x is the temperature of nitrogen and t is its boiling point at atmospheric pressure.
For example, if the boiling point of nitrogen is -320.44 °F, then the maximum temperature at which nitrogen is a liquid would be -320.44 + 12.78 = -307.66 °F, and the minimum temperature would be -320.44 - 12.78 = -333.22 °F.
