Which substance-oxygen or nitrogen- would freeze first if the temperature were gradually lowered?

If the temperature were lowered gradually enough for the substances to be in (approximate) thermal equilibrium, then nitrogen would freeze first. Nitrogen has an observed normal freezing point of 63.05 K, and oxygen has a freezing point of 54.85 K. As the temperature is lowered, nitrogen's higher freezing temperature occurs first.

Why water is 0'c is solid but nitrogen is gas?

Different chemicals have different physical properties, such as melting points (freezing points) and boiling points (vaporization points) waters freezing point is 0* C whereas nitrogen's freezing point is much lower.


What is a Substance with a really low boiling point?

Liquid nitrogen is one whose boiling point is way, way below the freezing point of water.


What is the freezing point of potassium hydroxide?

48% KOH freezing pt -11deg C 45% KOH freezing point -28 deg C The change in freezing point (always a decrease) = (number of ions in solution per molecule) x (Kf - the freezing point constant of the solvent) x (m - the molality of the solution, i. e. moles solute per kg solvent) For KOH in water, Freezing pt = 0 - 2(1.86)(molality of solution)


Is freezing nitrogen a chemical change?

No. Freezing a substance is a physical change.

Is cryogenic freezing related to nitrogen?

Cryogenic freezing is certainly related to nitrogen. In order to complete a deep cryogenic treatment a cryogen must be used. The least expensive cryogen for deep freezing is liquid nitrogen. Another cryogen is helium which allows special made cryogenic processors to reach temperatures approaching absolute zero.

When water is a liquid what is the physical state of nitrogen?

When water is a liquid, nitrogen is in a gaseous state. Nitrogen has a boiling point of -196°C, much lower than the freezing point of water, so it will be gaseous at room temperature when water is in a liquid state.
