So far, observations of Mercury from ground-based observers and the Mariner 10 spacecraft have not shown evidence of a significant atmosphere compared to other planets. Mariner 10 did observe a tiny amount of helium 1000 km above the surface, but this is probably caused by the solar wind and the breakdown of Mercury's crust. Sodium, potassium and oxygen have also been detected in Mercury's very weak atmosphere, but these elements can be lost when they react with the Sun and Mercury's magnetic field.

What makes Mercury's surface dry and almost airless?
Mercury has no Atmosphere, unlike Earth, which has an Atmosphere made out of Air. Mercury is dry because their is no water on Mercury.
What deos a barometer measure?
A barometer is used to measure air pressure. It measures the atmospheric pressure using air, mercury, or water and will be shown as inches of mercury or millibars.
When mercury water and air filled in three balls respectively qwhich has greater inertia?
Out of those substances, mercury has the greatest density. So for the same volume, mercury will be the heaviest and carry the most inertia.
What was the first liquid used in a thermometer?
The first thermometer was a tube filled with water and air.
What is an instrument that measures changes in air pressure using liquid mercury?
Any liquid can actually be use in a tube (barometer) to measure air pressure, but there are various advantages in using mercury for the purpose. 1. Mercury is a shiny liquid (a liquid metal) so it can be easily seen through the glass tube. Other liquid like water are transparent. 2. Mercury is very heavy. So only 76cms of it rises in the tube. Had you been using water for the purpose, you would need a glass tube as long as 55ft. 3. Mercury does not stick to the glass surface inside, so the reading obtained is much more accurate and precise. Remember: Water droplets stick to glass.
Dies Mercury have air and water?
No. Mercury has neither air nor water.
Is mercury an air or water planet?
Mercurcy is an air planet!!=]
How does the mercury from the air enter the water supply?
Since mercury is so heavy it falls out of the air. Landing on the ground (and water) and getting washed into our waterways and oceans.
Mercury is a small rocky planet and it has no water and?
Air
What makes Mercury's surface dry and almost airless?
Mercury has no Atmosphere, unlike Earth, which has an Atmosphere made out of Air. Mercury is dry because their is no water on Mercury.
Why mercury good heat conductor but not water?
Because you can see air
Can Mercury from the air get into water and build up in fish tissue.?
true
Is Mercury liveable or not?
No. Mercury has no air or water. It is extremely hot during the day and extremely cold at night.
Where is the water pump located on a 15HP mercury outboard?
The 15 horsepower Mercury outboard motor does not have a water pump. The outboard motor is air cooled and does not have a need for circulating water.
What accounts for the difference in heights of mercury vs water columns?
Density
What deos a barometer measure?

The velocity of sound is maximum in?
