Answer :
Final answer:
The freezing point of nitrogen is -210 degrees Celsius. On the Celsius scale, substances can lower the freezing point of water, such as salt which lowers it to -2 degrees Celsius. Hence negative integer represent the point.
Explanation:
The integer that represents the freezing point of nitrogen is -210 degrees Celsius. Freezing points are described in terms of temperature, most commonly on the Celsius scale. On this scale, the freezing point of water is 0 degrees Celsius. The degree to which substances lower the freezing point of a solution when added to water is referred to as freezing point depression. Salt, or NaCl, is indeed capable of lowering the freezing point of water, therefore when it creates a solution with water, the freezing point decreases to -2 degrees Celsius.
