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.

How does a solid form?
when the temperature is lowered below somethings melting point
What will happen to the pressure of a contained gas if its temperature is lowered?
If the temperature of the gas is lowered, its pressure will decrease as well, assuming the volume remains constant. This is because as the temperature decreases, the average kinetic energy of the gas molecules also decreases, leading to fewer collisions with the container walls per unit of time, resulting in lower pressure.
What will happen to a real gas when the temperature is lowered and the pressure is raised?
They show more deviation from ideal behaviour as the power of intermolecular forces increase.
How much salt is needed to stop 100ml of water freezing?
The freezing cannot be stopped; only the freezing temperature is lowered adding salts.
What happens to the reaction rate if the activation energy gets smaller?
When activation energy is lowered (e.g. by using a catalyst) the reaction rate increases (at the same temperature)
Will oxygen freeze faster than nitrogen if temperature was gradually lowered?
Yes!!
What happens to the solubility of salts when temperature is lowered or raised?
In general, the solubility of a salt increases as the temperature is raised, and thus decreases when the temperature is lowered.
What cellular event is being altered in cardiac tissue when temperature is raised or lowered?
When the temperature is raised, ensymic actibvity and metabolism increases. The opposite occurs when temperature is lowered.
When a star changes from blue to red what happens to the surface temperature?
The temperature is lowered.
What happens to the movement of molecules when their temperature is?
As the temperature is lowered, the movement of the molecules decreases.
When you move upward in the atmosphere what happens to the temperature?
When you move upward in the atmosphere the temperature get lowered.
What will happen to the pressure of a contained gas if its temperature is lowered?
If the temperature of the gas is lowered, its pressure will decrease as well, assuming the volume remains constant. This is because as the temperature decreases, the average kinetic energy of the gas molecules also decreases, leading to fewer collisions with the container walls per unit of time, resulting in lower pressure.
When particles in a solid slow down what does it become?
The temperature is lowered.
What happens to the temperature and humidity in a cold front?
Temperature is lowered. Humidity is increased in a cold front.
What happens to the density of objects when the get heated?
Raising the temperature the density is lowered.
How does a solid form?

What effect does solute have on the freezing points of the solution?
the temperature at which the solution freezes is lowered.
