What reaction would take place if hot tungsten was surrounded by air?
The reactions of tungsten with CO2 and D2O at high temperatures and low pressures (T >2000 K, 10−5 < P < 10−2Torr) has been studied using mass spectrometry. Under these conditions both reactants produce the same volatile oxide products which result in significant transport of tungsten compared to sublimation. The quasi-equilibrium model of gas surface reactions provides a good qualitative description of the rates of product formation. The fit is quantitatively satisfactory if the JANAF thermochemical values for the products are adjusted within their reported error. A comparison is made between these reactions and the reaction of oxygen with tungsten under similar conditions.
Can you explain what the term condensation means?
Condensation is the process where a gas or vapor turns into a liquid state when it cools down. This typically happens when warm, moist air comes into contact with a colder surface, causing the water vapor in the air to condense into water droplets.
What happens when copper touches air?
When copper comes into contact with air, it undergoes a process called oxidation. This leads to the formation of a thin layer of greenish patina on the surface of the copper, which can protect it from further corrosion. Over time, this patina may continue to develop and change in color.
What happens when you breathe on a window and water droplets appear?
When you breathe on a window, the warm air from your breath contains moisture. When this warm, moist air comes in contact with the cooler surface of the window, it rapidly cools down. As a result, the moisture condenses into tiny water droplets that appear on the glass.
What condition must exist for condensation?
Condensation occurs when the temperature of air is lowered to its dew point, causing water vapor to change from a gaseous state to a liquid state. This often happens when warm, moist air comes into contact with a cooler surface or cooler air.
What air is in a light bulb?
the basically unreactive gas argon (element) is in a light bulb to prevent the tungsten (element) filament from coming into contact with oxygen (element) and getting oxygenated.
When warm moist air comkes in contact with cool air what happens?
Usually rain showers or thunderstorms result.
What happens if you swallow air freshener?
I'd say contact poisen control but thats just my opinion.
What happens when two objects having different temperatures come in contact with each other?
Air masses
What brings air into contact with blood?
In the human body, air is brought into contact with blood in the lungs. This happens through the process of respiration, where oxygen from the air diffuses into the blood in the capillaries surrounding the alveoli in the lungs, and carbon dioxide from the blood diffuses into the air to be exhaled.
Is air resistance a contact or non contact force?
Air resistance is a contact force because you are in contact with the air in order to apply that force.
When was Contact Air created?
Contact Air was created in 1974.
What happens when you release gases into the air?
Gases mix together when they contact each other. There are no immiscible gases like there are immiscible fluids.
What happens to the air at night?
what happens to air when it touches the warmed air
Why is there water outside the glass of water?
This is due to condensation. When air comes in contact with the glass it condenses(this happens only when the water inside is cold).
What is wrong when your 2000 Lincoln Navigator rear is low?
youre automatic air ride suspension went out it happens to alot of navigators/expeditions that came from the factory with rear air ride shocks
Is air resistance a contact?
it is contact force
