Did you know that ionizing smoke detectors contain about 25 micrograms of Am-241, a radioactive element? As it decays, high energy alpha particles are released, which ionize surrounding air particles. This makes the air slightly more conductive, and the detector has circuitry designed to sense tiny changes in conductivity. Smoke particles will react with the ions formed from the alpha particles, and when they do the airs conductivity drops, triggering the alarm! #chemistry #chemteacherphil #radioactivity #learnontiktok #bettercallsaul
I found everything I needed to do a really cool reaction between copper (II) chloride and aluminum at the hardware store! The copper chloride is made through a double displacement reaction that occurs between solutions of copper (II) sulfate, found in tree root killer, and calcium chloride, a common salt used to melt ice in wintertime. The reaction between copper chloride and aluminum generates hydrogen gas, which is very flammable! The blue green colors you see are the result of electrons in copper ions gaining and losing energy. #learnontiktok #chemistry #chemteacherphil
Forging the perfect sword requires making a metallic blade with just the right number of defects (called dislocations) in the metal that makes the blade. Too many dislocations and the blade is too hard and brittle, and too few makes the blade too flexible. Its all about making the ideal metallic crystal, and using chemistry to do it! #learnontiktok #forgedinfire #chemteacherphil
Yes, it is possible to boil water in a paper cup without the cup catching fire! Once the water inside the cup reaches 100 C, all of the energy from the flame is used to change the water from liquid to gas; the temperature stays constant, and the cup doesnt burn! #learnontiktok #tiktoktaughtme #chemteacherphil
