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.

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?
When the temperature is lowered and the pressure is raised on a real gas, the molecules will move more slowly and be forced to be closer together. This can lead to the gas condensing into a liquid or solid, depending on how low the temperature goes and how high the pressure is increased.
When gas turns to liquid it's called?
When gas turns to liquid, it is called condensation. This process occurs when the temperature of the gas is lowered, causing the particles to come closer together and form a liquid.
When a gas reaches its condensation point it becomes?
When a gas reaches its condensation point, it becomes a liquid. This transition happens when the temperature of the gas is lowered to the point at which its particles lose enough kinetic energy to come together and form a liquid.
For what sounds would the velum be lowered?
The velum is typically lowered for sounds produced with the oral cavity, such as vowels and most consonants. When the velum is lowered, air flows through the oral cavity, allowing for sounds to be articulated without passing through the nasal cavity.
Will oxygen freeze faster than nitrogen if temperature was gradually lowered?
Yes, oxygen will freeze faster than nitrogen under the same conditions due to its higher freezing point (-218.8°C for oxygen compared to -210°C for nitrogen). Since oxygen freezes at a higher temperature, it will solidify more quickly as the temperature drops.
What happens to the solubility of salts when temperature is lowered or raised?
When temperature is lowered, the solubility of most salts decreases because the solubility of solids generally decreases with decreasing temperature. Conversely, when temperature is raised, the solubility of most salts increases as the solubility of solids typically increases with increasing temperature.
What happens to the movement of molecules when their temperature is?
As the temperature is lowered, the movement of the molecules decreases.
When a star changes from blue to red what happens to the surface temperature?
The temperature is lowered.
When you move upward in the atmosphere what happens to the temperature?
When you move upward in the atmosphere the temperature get lowered.
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.
What expands most when the temperature is lowered water or helium or iron or wood?
Iron expands the least when the temperature is lowered, followed by wood and then water. Helium does not expand or contract significantly with changes in temperature due to its unique properties as a gas.
What cellular event is being altered in cardiac tissue when temperature is raised or lowered?
When temperature is raised, the cellular event affected in cardiac tissue is an increase in heart rate due to a higher metabolic rate. Conversely, when temperature is lowered, the cellular event influenced is a decrease in heart rate as a result of reduced metabolic activity. These temperature shifts can impact the heart's functioning and electrical activity.
What is caused by cold exposure results in lowered internal body temperature?
Hypothermia.
What effect does solute have on the freezing points of the solution?
the temperature at which the solution freezes is lowered.
