Well the science behind using carbon dioxide is kinda simple! Why are they made? To catch people like asylum-seekers and refuges who are doing bad. They detectors sense carbon dioxide. Carbon dioxide is science so you have to explain about carbon dioxide and respiration. We give out co2 afta breathin in oxygen right? well that's science! there you go quite simpal init..?!
Smoke detectors typically contain americium-241. This radioactive isotope is used to ionize the air in the detector, allowing it to detect smoke particles and trigger the alarm.
Carbon dioxide (CO2) enters the Calvin cycle from the atmosphere. This CO2 is used by plants during photosynthesis to produce glucose.
Co2 is not combustible - it is the end product of combustion reactions or the decaying organic matter and will not be broken down any further by that mechanism. Most of the world's CO2 is produced by rotting trees and matter decaying in our Oceans (96%). co2 in used in combustion of biomass i.e co2 biomass gasification. this is only possible at higher temperatures. co2 can used in chemical synthesis co2 is used produce ch4 ( carnol process) co2 supports combustion of metals. search in sciencedirect.com
Ammonium hydroxide can be used to capture CO2 through a process known as carbon capture and storage (CCS). In this process, the CO2 is absorbed by the ammonium hydroxide solution, forming ammonium carbonate. The ammonium carbonate can then be further processed to extract the CO2 for storage or utilization.
I'm assuming you're talking about the absorption of CO2 into water. CO2 free water is used to properly measure the amount of CO2 water can actually absorb. CO2 already in the water will reduce the mass of CO2 transferred from the gas, and while I don't believe that there is a specific point at which CO2 can no longer be absorbed by water, the tendency for CO2 to be absorbed into water with CO2 already in it is reduced.
CO2 detectors are used for detecting levels of carbon monoxide in the air. Many people use CO2 detectors in their homes to prevent carbon monoxide poisoning.
i dn't
the co2 Detectors detects co2 and in the thing they should be about 0.03 co2 if not they something living in there
CO2 (carbon dioxide) is present in the breath exhaled by the body. Sensitive CO2 detectors sample the air from inside trucks as they arrive from Europe. They can detect illegal immigrants hiding in the truck as the level of CO2 would be higher than it would be if people hadn't been in there breathing out CO2 for ages while the truck crossed The Channel.also they of couldn't of breathed with air for the the journey
Rechargable batteries are a good option for CO@ detectors,please make sure you cahrge them regularly.
CO2 detectors should be placed on every level of the home, near sleeping areas, and in areas where carbon monoxide sources are present, such as near gas appliances or a garage.

The first smoke detectors are based on optical principles - photoelectric detectors.
they were used in border control because they were trying to stop illegal immigrints going from country to country;so the detectors monitor the level of co2 in the lorry and if it is over a certain number they searched the lorry wolfiepagefan001
Laser detectors detect laser beams used by law enforcement to measure speed, while radar detectors detect radio waves used by police radar guns. Laser detectors are more precise but have a shorter range compared to radar detectors. It's recommended to have both types of detectors for comprehensive coverage.
