碳酸化是测量为'体积'或每升克。一体积意味着一升饮料中含有一升二氧化碳。这相当于1.96克/升(通常报价为2克/升)。一杯典型的碳酸软饮料含有大约3-4体积(6-8克/升)的二氧化碳。< / p >
Assuming the low end of 3 liters CO2 gas per liter soda we get each milliliter of soda contains 0.003 liter CO2. Ambient air has about 400 ppm CO2 or 0.04%, or about 0.0004 liters CO2 per liter air, so to bring it up to about 1500 ppm I would need to add 0.0011 X 10 or 0.011 liters CO2 to the greenhouse, or about 4ml of carbonated water.
The problem is this whole process is very imprecise, and it would be nice if there was a way to measure the CO2 content within 100 ppm with a range of say 0 - 5000 ppm which doesn't cost hundreds of dollars, since this is a 9th grade science project.
Any ideas?
