2020年9月23日 · We hear a lot about carbon dioxide when we talk about climate change, but sometimes it's important to go back and examine why too much CO2 in the atmosphere is a bad thing.

2021年2月25日 · With CO2 and other greenhouse gases, it’s different. Carbon dioxide, for example, absorbs energy at a variety of wavelengths between 2,000 and 15,000 nanometers — a range that overlaps with that of infrared energy. As CO2 soaks up this infrared energy, it vibrates and re-emits the infrared energy back in all directions.

2023年2月6日 · Carbon dioxide is what people and animals breathe out after breathing in oxygen. But that's balanced by the plants we eat, so humans and animals aren't affecting the balance of atmospheric CO 2.

2023年1月19日 · Molecules of carbon dioxide gas (CO₂) consist of one carbon atom and two oxygen atoms. Carbon dioxide is a natural constituent of our air, but its concentration is very low. CO₂ makes up only about 0.04 percent of the air by volume; air is mostly nitrogen and oxygen. That doesn’t sound like much, but CO₂ still plays a very important role.

2023年1月20日 · Carbon dioxide, also known as CO 2, is a simple molecule that makes life on Earth possible. CO 2 is called a trace gas because it makes up less than 1 percent of the atmosphere. Even that small amount, however, plays a big role in shaping Earth’s climate.

2013年4月30日 · So, right now, CO2 should be at a short term peak. The range of this variation is around 8 ppm, so if we hit, say, 401 ppm next week, expect that value to go back below 400 ppm in a few weeks.

The drop checker is not accurate so should not be your main indicator for CO2 dispersion. It’s best to measure your kH and pH and then use this chart. Tom Barr recommends you have a saturation of between 30-40ppm which is in the red zone for optimal health of your plants without affecting your inhabitants.

2013年6月11日 · Was thinking of making a co2 thing using yeast, but when I looked at the store all the yeast has other stuff in it, is it still ok to use? Or do I need to track down some 100% pure yeast?

a process in living organisms involving the production of energy, typically with the intake of oxygen and the release of carbon dioxide from the oxidation of complex organic substances.
