Why when were outside and speak fog comes out?
When you speak in cold or cool weather, the warm air from your lungs meets the cold air outside, causing a rapid cooling and condensation of water vapor in your breath. This forms tiny water droplets that create the illusion of fog.
How can you show you breath out water vapour?
You can demonstrate that you breathe out water vapor by exhaling onto a cold surface, such as a mirror or glass. The moisture in your breath condenses upon contact with the cold surface, forming tiny droplets that create a foggy appearance. Alternatively, you could use a hygrometer to measure the humidity in your breath, showing the presence of water vapor.
What is the precipitation on mercury?
Mercury has a very thin atmosphere that consists mainly of oxygen, sodium, hydrogen, helium, and potassium, with trace amounts of water vapor. Due to its low gravity and proximity to the Sun, any water vapor present on the planet is quickly lost to space. As a result, there is no significant precipitation on Mercury.
Which process happens when water vapor forms clouds in the sky?
Condensation.
What happens when the water vapor in the air condenses?
It rains, or maybe hail storm or a snowstorm.
What is the optimal mercury vapor temperature for efficient operation of a mercury vapor lamp?
The optimal mercury vapor temperature for efficient operation of a mercury vapor lamp is around 700 degrees Celsius.
When alchohol and mercury boil they both change from a liquid to what?
They change from a liquid to a vapor (gas).
Where does the water vapor in your breath comes from?
The water vapor in your breath comes from water contained in your body, particularly in your lungs and airways. As you exhale, this water is released into the air in the form of vapor.
What happens to your breath when it is 90 degrees Fahrenheit outside?
The reason you can see your breath in cold weather is because the water vapor in your breath is condensing (condensation). You can't see it in hot weather because condensation can't occur in warmer weather.
How does a mercury vapor light work?
A mercury vapor light works by passing an electric current through mercury vapor inside a sealed tube. This process causes the mercury vapor to emit ultraviolet light, which then excites a phosphor coating on the inner surface of the tube to produce visible light.
What phase change happens when glass mists up from breath?
Water in the vapor phase changes to liquid phase due to the cooler glass temperature.
How does vapor change to liquid?
It condenses, this is what happens when the particles in a gas cool down. If you breath onto a piece of glass you can see a small amount of condensation
What is Mercury vapor?
Mercury vapor is the element mercury in the gas phase. It must be a pretty high temperature or low pressure because mercury doesn't turn into a gas very easily!
Why can you see your breath on a cold mirror?
What happens here is the following: You have water vapor in your breath; when it cools down (as when it gets near the cold mirror), the air can hold less humidity (it becomes saturated), and some of the water condensates.
How might you distinguish a sodium vapor streetlight from a mercury vapor streetlight?
Mercury vapor streetlights, used since the 1940s, glow a greenish white. Sodium vapor streetlights, which have gradually replaced most of the MV streetlights in the US, glow orange. Another two, metal halide and LED, glow completely white.
Has mercury got air to breath?
no
Can mercury evaporate?
Yes, at room temperature its vapor pressure is about 0.1 Pa (0.0001 kPa, 0.000001 atm.). Be carefull, vapor of Mercury is very toxic.
