What instrument measures changes in the atmosphere?

Answer 1

There are many types of instrument used to measure air pollution. Different types include:

• Absorption plates trap pollutants such as sulfur dioxide on a reactive plate for a measure of air contaminants
• An a high volume air sampler is used to measure pollution levels in the atmosphere by collecting solids on a filter paper
• Lasers measure contaminants by the amount of light reflected or removed by specific chemical contaminants in the air between the emitter and receiver
• Field gas chromatography passes air through a packed column to measure types of gaseous contaminant
• Air samples can be taken an stored in Teflon bags for later laboratory analysis
• Scrubbers can collect contaminants from an air sample in the field for later analysis
• Phytotoxicolgic chambers can pass air over plants to determine the impact on plant growth
• Opacity meters measure haze

Answer 2

A barometer is an instrument that measures changes in atmospheric pressure, which can indicate weather patterns. Another instrument, called an anemometer, measures wind speed and direction in the atmosphere.

Answer 3

Air quality is a wide definition. Most organisations measure ground-ozone levels (using an ozone detector), sulfur dioxide levels (using a sulfur dioxide detector) and carbon mono/dioxide (carbon detectors).

Answer 4

Air pollution can be made up of solids, liquids and gases. Each requires a different instrument. Solids are separated from the air stream and subjected to lab style analysis or instrumental analysis as well as microscopic examination. Liquids and gases can be collected and concentrated for gas chromatographic examination or by passing lasers through ambient air for absorption or reflection spectrum analysis.

Answer 5

With a simple balance you can find the weight (weight = mass in this case) of air.

I propose the following method.

Take the weight of the container (suppose it is a 1 litre container). And the weight is x kg. Take weight of the container full of water, say it is y kg. Weight of 1 litre of water is 1 kg. So the weight of the container is 'y -1' kg.

So the weight of the air in it is 'x - y +1' kg. It should be around 1.2 gm.

Answer 6

An anoride Berometer is used to meashure the changes of the atmosphere.

Answer 7

we use an barometer answered by Kavya JAIN

Answer 8

Air pollution is typically measured in parts per million.

Answer 9

A mass spectrometer can measure mass and identify the molecules in air.

Answer 10

A barometer measures pressure while a thermometer measures temperature.
