What does weather inches in pressure mean?
Air pressure measured in inches of mercury indicates the level to which a column of mercury rises after being set to a standard pressure initially. One end of the bent mercury tube is closed off, preserving the pressure that existed at the time the tube was closed. Changes in the level of mercury on the other side of the tube reflect changes in air pressure.
When air pressure goes up the liquid in a mercury barometer goes?
rises
Does air pressure affect earths weather?
It expands, rises, and becomes less dense.
As the elevation of land rises the weather generally become what?
Colder, but only after 1000's of feet at a time
A balloon carrying weather instruments is released at Earth's surface and rises through the troposphere as the balloon rises what will the instrument generally indicate?
A increase in air temperature and a decrease in air pressure
What are some uses for the element Mercury?
Mercury can be used in thermometers, When the heat rises, the mercury- seeing as it is a metal- expands and rises up the thermometer, henceforth telling you the temperature, Mercury can also be used in Batteries.
Why is there mercury in thermometers?
because when it heats it rises
What a barometer with Mercury?
barometers with mercury measure air pressure. when the air pressure is high the mercury rises
When air pressure decreases the mercury in a barometer?
The mercury rises. The lower atmospheric pressure allows the mercury to drop in level.
How does a liquid thermometer show that you have a fever?
That type of thermometer has mercury in it, which is very heat sensitive. When used for taking a temperature, the heat from the body causes the mercury to rise. The amount the level of the mercury rises is determined by the body's temperature; the higher the temp, the higher the mercury rises.
What happens to the volume of mercury as the temperature increases?
The volume increases, which is why the mercury in a thermometer rises as the temperature increases.
What material is used for thermometer?
Mercury is used in thermometers. The mercury is the red substance in the thermometer that rises when you put it in your mouth.
What does weather inches in pressure mean?
Air pressure measured in inches of mercury indicates the level to which a column of mercury rises after being set to a standard pressure initially. One end of the bent mercury tube is closed off, preserving the pressure that existed at the time the tube was closed. Changes in the level of mercury on the other side of the tube reflect changes in air pressure.
A decrease in the height of a column in a mercury barometer means that .'s surface?
When air pressure increases, the mercury in a barometer rises.
Why doesn't mercury fall in thermometers?
Mercury based thermometers have a column of mercury which visibly rises or falls, according to the temperature. So it does fall, when it gets colder.
When air pressure goes up the liquid in a mercury barometer goes?
rises
How mercury functions in a thermometer?
Mercury, like most substances, expands when it gets hotter and contracts when it gets colder. A mercury thermometer is designed so that the volume of the mercury can be accurately observed, as the mercury rises or falls in a marked column.
