Question

why does a cooking gas cylinder become lighter after it has been used for a few days.​

Answer 1

Explanation:

because it is lighter. The gas comming out is liquid inside the cylinder and the liquid is heavy. the liquid instantly changes to gas as its released into atmosphere, which is at a far lower pressure than inside the tank.you've used up a portion of the heavy liquid inside.

hope this helps uh☺️❤️

mark me as brainliest ❤️☺️

Answer 2

• Cooking gas cylinders contain LPG (liquefied petroleum gas).

• Thus, liquid evaporates and goes out of the cylinder gradually, as we use and finally, gets empty.

• This makes it light when the cylinder becomes empty.
