Because there is no air in the tube, but if you open one and re-cap it, you admit air and it will harden eventually.
Because there is no water in the tube, water is necessary to start the hardening process.
To prevent a hot glue tube from becoming stuck, always recap the tube securely after use and store it in a cool, dry place. Try to avoid leaving the tube lying flat after using it, as this can cause the glue to dry around the cap and nozzle, making it difficult to open. If the tube does become stuck, soaking it in warm, soapy water can help loosen the dried glue and make it easier to open.
Glue hardens when exposed to air due to a process called polymerization. When glue is squeezed from the tube, it comes in contact with air, leading to the evaporation of solvents or water present in the glue. This causes the glue molecules to come closer together and form a strong bond, resulting in hardening.

No, it simply heats the glue, then it is pushed out of the tube.

To repair an inner tube using inner tube repair glue, follow these steps: Locate the puncture or hole in the inner tube. Clean and dry the area around the puncture. Apply a thin layer of inner tube repair glue to the punctured area. Wait for the glue to become tacky. Press a patch onto the glued area and hold it in place for a few minutes. Allow the glue to dry completely before inflating the inner tube.
