Short answer: This is normally done when a lid is too tight to unscrew. Placing the lid in warm or hot water loosens the lid a little so someone can get to the contents of the jar easier.
Long answer: Metal reacts to heat at a lower temperature than glass does. When a metal lid is placed in warm or hot water, the lid expands outwardly from its center. This will cause the lid to loosen its grip on the jar making it easier for a user to unscrew the lid. It's simple science and a neat trick.

Why the stems of a harvested jute plant are kept immersed in water for a few days?
The stems of harvested jute plants are kept immersed in water for a few days to facilitate the retting process. Retting helps to break down the pectin and other substances that bind the fibers to the stem, making it easier to separate the valuable jute fibers. This process also helps in softening the stalks and improving the quality of the fibers by reducing impurities. Ultimately, immersing the stems in water enhances the efficiency of fiber extraction.
