Can plastic be converted back to oil?
|
view preview
Start by watching the video below In the video, a Japanese man converts plastic waste into usable oil and fuel using a machine that thermochemically decomposes the plastic in a process known as pyrolysis. Pyrolysis works by thermochemically breaking down material at temperatures above 350 degrees Celsius in the absence of water. This not only physically melts down an object, but also changes its chemical composition so that, in the case of plastic waste, it reverts back into boiling liquid and eventually gas.

How to check for dead batteries
|
view preview
Dead or depleted batteries, especially cylindrical ones like AA or AAA batteries, can exhibit a unique behavior known as "bouncing" when dropped from a short height. This phenomenon is primarily due to changes in the battery's internal chemistry and physical properties as it becomes discharged. Inside a battery, there are chemical reactions that generate electrical energy. As a battery discharges and its chemical energy is depleted, its internal chemistry changes. One of the changes that occur is a reduction in the pressure of gases within the battery. This decrease in gas pressure can make the battery feel lighter, contributing to its bounce. As a battery discharges, its internal components, such as the cathode, anode, and electrolyte, unde ...

When chemistry and physics come together, it looks awesome. This is the emission spectra of the Elements - in other words, these are the colors they emit in the gaseous state.
