Because it's thinner after you heat it.

Epoxies and cyanoacrylite will. Not many others.
You get warm, weak glue.
Warm water and a little scrubbing can remove white glue or school glue.
Generally, cold air will not do anything for any glue. Some adhesives,especially many epoxies will benefit from warm air. Some other adhesives, particularly those with 100 % silicon will harden faster under cold,running water.
Some glues like epoxy dry faster when hotter, others like silicon based adhesives dry faster under cold conditions. -All glue is different . When asking an adhesive or glue question, simply saying "glue" is not enough information.
You can glue things faster and more easily with a glue gun than with a tube of glue (although I still use tubes, personally).
No, most glues are not electrically conductive.
You can remove nail glue from the back of fake nails by soaking them in warm soapy water for a few minutes to soften the glue. Gently peel or scrape off the glue residue using a cuticle pusher or orange stick. Repeat the process if necessary until all the glue is removed.
You blow dry it or heat it
Blood flow is faster in arteries than in veins. Blood flow in veins is lower pressure.
Nails grow faster in warm climates than cold weather areas, because cold weather decreases blood stimulation and blood pressure. Nails grow fastest in summer, so take advantage of the summer months. To mimic warm weather try wearing gloves and keeping your hands warm at all times. This will increase the blood flow and stimulate growth
