Ppm stands for parts per million. It is a way of showing the amount of one substance in another, like carbon dioxide in the atmosphere, especially when the percentage number is small.
For example, in July 2011, the amount of carbon dioxide in the earth's atmosphere was 392.39 ppm (or 0.039239%).
What else can I help you with?
By how much have carbon dioxide emissions increased its atmospheric percentage over the past 250 years?
CO2 levels were about 260-280 ppm immediately before industrial emissions began and did not vary much from this level during the preceding 10,000 years. The concentration of carbon dioxide (CO2) in Earth's atmosphere has reached 391 ppm (parts per million) as of October 2012. ((391-260)/391)*100 = 33.50 Thus there has been a 33.5% increase in the levels of CO2 in Earth's atmosphere over the past 250 years.
What is the concentration in parts per million (ppm) of CO2 in rainwater with a pH of 5.6?
The concentration of CO2 in rainwater with a pH of 5.6 is approximately 10 parts per million (ppm).
Why do you expect seasonal variation in the atmospheric CO2 levels?
Global carbon dioxide levels are highest in May and lowest in October. The Northern Hemisphere has much more land for vegetation to grow on compared to the Southern Hemisphere. Carbon dioxide (CO2) builds up slowly during the northern winter, when trees and plants are dormant. Then in May everything begins to grow, and CO2 is taken out of the atmosphere, so the levels start coming down. In October and November vegetation stops growing, and in its dormant state it stops absorbing CO2, so the carbon in the atmosphere increases. These levels go up and down like this every year. The readings for 1958, 1959 and 1960 show this: 1960: May: 320.5 ppm: October: 314.5 ppm 1959: May: 320.0 ppm: October: 313.5 ppm 1958: May: 318.0 ppm: October: 313.0 ppm Ppm means parts per million, so 320 ppm is the same as 0.032 percent (per hundred). The recent readings for May are: 2011: 394.35 ppm 2010: 393.22 ppm 2009: 390.18 ppm See the graph at the link below.
Largest producer of CO2?
China is the largest producer of CO2 emissions in the world, followed by the United States and India.
Is there a strong connection between CO2 emissions and global climate change?
Yes, there is a strong connection between CO2 emissions and global climate change. CO2 is a greenhouse gas that traps heat in the atmosphere, leading to increased temperatures and various climate impacts such as rising sea levels, changes in precipitation patterns, and more frequent extreme weather events. Reducing CO2 emissions is vital to mitigating the effects of climate change.
How much have the world's CO2 level risen in a decade?
In 2003 carbon dioxide emissions were 370 ppm (parts per million). This year (2013) they reached 400 ppm. At the beginning of the Industrial Revolution they had been 280 ppm for thousands of years.
How ppm is used in cars?
In measuring exhaust emissions.
How much ppm are there in co2 fire extinguisher?
It should be at least 99.5 percent CO2.
How do you figure ppm of CO2 in the air?
To calculate the parts per million (ppm) of CO2 in the air, you would measure the concentration of CO2 in the air using a CO2 sensor or monitor, and then divide that by the total volume of the air sample. This would give you the ppm of CO2 in the air sample. Common methods include using infrared gas analyzers or chemical absorbents.
CO2 probe sensor?
A CO2 probe sensor measures gaseous carbon dioxide. It comes in two ranges, 0 to 10,000 ppm and 0 to 100,000 ppm.
By how much have carbon dioxide emissions increased its atmospheric percentage over the past 250 years?
CO2 levels were about 260-280 ppm immediately before industrial emissions began and did not vary much from this level during the preceding 10,000 years. The concentration of carbon dioxide (CO2) in Earth's atmosphere has reached 391 ppm (parts per million) as of October 2012. ((391-260)/391)*100 = 33.50 Thus there has been a 33.5% increase in the levels of CO2 in Earth's atmosphere over the past 250 years.
What is smoke density?
measures how many (usually) parts per million (ppm) of whatever smoke/gas/etc is being looked for. For instance a smoke detector looks for X ppm of smoke in air, or a CO2 sensor measures the ppm of CO2 in air - ppm is a measure of density.
What is the concentration in parts per million (ppm) of CO2 in rainwater with a pH of 5.6?
The concentration of CO2 in rainwater with a pH of 5.6 is approximately 10 parts per million (ppm).
What is smoke density analyser?
measures how many (usually) parts per million (ppm) of whatever smoke/gas/etc is being looked for. For instance a smoke detector looks for X ppm of smoke in air, or a CO2 sensor measures the ppm of CO2 in air - ppm is a measure of density.
What does ppm mean relating to an emissions test?
Parts Per Million.
Why is it dangerous to keep increasing the amount of CO2 in atmosphere?
We won't asphyxiate. But CO2 is a heat trapping gas, and it takes decades for the earth to adjust to any slight rise. Human activity has increased CO2 levels from 280 ppm prior to the industrial revolution to nearly 400 ppm today. We will pass 500 ppm before 2050, at the current rate. Many climate scientists believe 350 ppm may be the maximum sustainable level for CO2.
How do I convert 10 percent CO2 to parts per million CO2?
-- Take the number of percent. -- Multiply it by 10,000-- The answer is the number of parts per million. . 10 percent = 100,000 parts per million.
