Oxygen, O2, has a boiling point of 90 K (-183 ∘C), and nitrogen, N2, has a boiling point of 77 K (-196 ∘C). Which is a liquid and which is a gas at 95 K (-178 ∘C)? Oxygen, , has a boiling point of 90 (-183 ), and nitrogen, , has a boiling point of 77 (-196 ). Which is a liquid and which is a gas at 95 (-178 )?

Explanation:

Boiling point is the temperature at which vapor pressure of a liquid becomes equal to the atmospheric pressure.  

More strong interactions present in the atoms of a compound more heat is required to break it. Hence, greater will be its boiling point.

As the boiling point of oxygen is 90 K so, at a temperature greater than it will change the state of oxygen from liquid to gas.

Similarly, the boiling point of nitrogen is 77 K so, at a temperature 95 K the state of liquid will also change from liquid to gas.

the answer is true.
