🤔 How it works …….. ⁉
How a Hot Air Balloon will Fly?
Hot air balloons are based on a very basic scientific principle: warmer air rises in cooler air. By heating the air inside the balloon with the burner, it becomes lighter than the cooler air on the outside. This causes the balloon to float upwards, as if it were in water. Obviously, if the air is allowed to cools, the balloon begins to slowly come down.
😳Why❓❓❓
Why can’t normal batteries be recharged?
Single-use batteries (also known as primary batteries), can only make the electrons take a trip from the anode over to the cathode one-way once.
The most popular non-rechargable battery types are alkaline and zinc-carbon. Both of these kinds of batteries produce electricity by means of a chemical reaction with the chemicals inside them. As they produce electricity, the chemicalst transform into a different chemical.
The process for alklaine (non-rechargeable) batteries is not reversible, which is why they cannot be recharged. The rechargeable ones like lithium-ion are reversible, hence they can be recharged.
Batteries discharge even if not used, because the chemical reaction goes “forward” anyway, although much more slowly.
