A single chirp from your smoke alarm usually means the battery is low and needs to be replaced.
Your smoke detector emits a single beep to indicate a low battery or a malfunction.
Smoke detectors use a small amount of radioactive material (usually americium-241) to emit alpha particles. When smoke enters the detector, it scatters the alpha particles, disrupting the electric current within the detector and setting off the alarm.
Many of them do
A fire alarm system will indicate a FIRE EMERGENCY requiring immediate action. The system shall alert all occupants of a building where it is installed when a fire emergency is present.
The particles released by radioactive sources in smoke alarms, typically americium-241, emit alpha particles. These charged particles ionize the air in the sensing chamber, creating a current. When smoke enters the chamber, it disrupts this current, triggering the alarm to alert occupants of potential danger.
you're gay, that's why
Americium-241 is used in smoke detectors as a source of alpha particles, which ionize the air within the detector. When smoke particles enter the detector, they disrupt the ionization process, causing a decrease in the electric current flow and triggering the alarm to go off.
Yes, you just use the smoke maker. It is found in your gadgets bag on the 2nd page.
Home smoke detectors generally respond to smoke, or products of combustion more readily than heat. Unless the candle was placed directly under the detector, it is unlikely to produce enough heat to trip a heat element. It is very possible though, that it could give off enough combustion products to set off the smoke detector.
coke probably does emit gases, but you dont see them cause they are clear, but it doesnt emit smoke, which i am guessing would refer to carbon dioxide, because burning coke does not create it as one of its products. i am not sure what coke has in it exactly, so if someone can explain better then please do.
A blown head gasket
One reason could be a worn engine.
