Is glue drying a chemical reaction?

When paste or glue “dries” it is actually undergoing a chemical reaction so this is not a phase transition as in the phases matter. Many chemical reactions may start with compounds in one state that change to another; examples are fire, precipitates in solution, cement etc….

Is glue a chemical reaction?

As the polymers dry, the liquid evaporates and the solid, sticky adhesive stays behind. Other glues help things stick because of a chemical reaction. Silicone and cyanoacrylate glues, like Krazy Glue and Gorilla Glue, react with water vapor in the air and harden through a chemical reaction.

Which of the following is an example of physical change in matter?

Examples of physical changes are boiling, melting, freezing, and shredding. Many physical changes are reversible, if sufficient energy is supplied. The only way to reverse a chemical change is via another chemical reaction.

What is an example of physical change?

Examples of physical change include changes in the size or shape of matter. Some of the processes that cause physical changes include cutting, bending, dissolving, freezing, boiling, and melting.
