Consider the statement below. “when nitrogen is liquefied, heat is released.” is this statement true or false? it is false because nitrogen absorbs heat when it is liquefied. it is false because nitrogen cannot absorb enough heat to liquefy. it is true because heat is released when a gas changes to a liquid. it is true because heat is released when a liquid changes to a gas.

Option-3: (It is true because heat is released when a gas changes to a liquid) is the correct answer. 

Explanation:
                   When nitrogen is in gas phase there is no or neglegible intermolecular interactions between the Nitrogen Molecules. Also, we know that a bond breakage is a endothermic reaction means it requires energy to break the bonds. On the other hand bond formation is an exothermic reaction (reverse of bond breakage), So the same amount of heat will be released which was absorbed during bond breakage.
                    Therefore, on the formation of intermolecular interactions (bond forming) Nitrogen will change from gas to liquid phase with the elimination of extra energy in the form of heat.
