How much CO2 ppm do human lungs exhale on average?
It depends on a number of factors such as age, heart rate and depth of breathing. However, on average a human being exhales around 40,000 PPM of CO2.
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.
Is 310 ppm of carbon dioxide allot?
No: it is not much (a lot) 310 ppm = 310 mg per kg = 0.310 g/kg = 0.0310 g/100g = 0.0310% CO2
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 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.
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.
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.
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.
How many parts per million of CO2 is 2.5 mole?
1.50553543e+30 ppm
What ppm amount is 0.04 percent CO2?
0.04 percent is 400 per million.
What is above normal levels of carbon dioxide?
Above 400 ppm of co2 would be considered high.
What year will global warming start?
It's happening now and is a constant occurrence. Measurements of abnormally large temperature upswings were first made in the 1980s. We have broken numerous records since then. In 1950 earth's CO2 level exceeded 300 ppm for the first time in more than 800,000 years. CO2 naturally rises or falls by roughly 10 ppm over a thousand years. Between 1950 and 2014 CO2 will have risen from 300 ppm to 400 ppm, and we will exceed 500 ppm before 2050, less than 40 years from now. The temperature is expected to continue climbing for decades to come, just on the basis of present CO2 levels.
