In most laboratories, with great difficulty. Mercury is a highly toxic substance and its use is very strictly controlled.
A mercury barometer is simple because the height of the mercury column would be 760 mm (approx 30 inches). Mercury has a density which is around 13.6 times that of water. The next most dense fluid which is readily available (and safe) has a density which is about a tenth as much. For this, you would require a column which was about 7.6 metres (25 feet) tall! That is not a simple piece of equipment.
The straw moved up and down in a homemade barometer due to changes in atmospheric pressure. When the pressure increased, the liquid in the bottle pushed the straw up. When the pressure decreased, the straw moved down due to the weight of the atmosphere pressing down on the liquid in the bottle.
If air pressure is getting lower, you would expect to see the mercury in Torricelli's barometer rise. This is because low air pressure allows the mercury in the barometer tube to be pushed up by the weight of the atmosphere.
A barometer typically consists of a glass tube filled with mercury or a liquid metal, sealed at one end and open at the other. The open end is placed in a container of mercury, allowing atmospheric pressure to push the mercury up the tube. The height of the mercury column is a measure of the atmospheric pressure.
hahahaha i cant believe u looked at this question
As you go to a higher altitude, the barometer reading would decrease because atmospheric pressure decreases with increasing altitude. This is due to the lower density of air molecules at higher altitudes.

If you were looking to set up a simple carp rig, you could visit the "Anglers Mail" site which provides a procedural page which tells you how to set up a simple carp rig.
If you have taped a straw to a balloon stretched over a jar top as a simple barometer, when the straw moves up, this is a sign of high pressure (atmosphere pressing down on the balloon). High pressure usually means fine weather.
Kill the person who is really beautiful set-up
yes
An ecolgists may set up an artificial environment in a laboratory to imitate and manipulate conditions that organisms would encounter in the natural world.An ecologists may set up an artificial environment in a laboratory to imitate and manipulate conditions that organisms would encounter in the natural world.
Simple. Plug it into the back of the TV
because its hard to understand
In a laboratory technician job, you must set up and maintain laboratory equipment. You may also prepare reagents needed for a certain procedure. Occasionally, you might need to instruct and work with other laboratory technicians.
Nothing
it goes up. :D
