Is mixing elmers glue and liquid starch a chemical change?
No, mixing Elmer's glue and liquid starch is a physical change. A chemical change involves the formation of new substances with different chemical properties, while mixing these two substances does not result in a chemical reaction.
What are the chemical properties of glue?
There are plenty of different glues, and pretty much they only have two things in common:they have a certain mechanical strengththey stick to stuffApart from that, they can be just about anything. Some harden by evaporation, some through a chemical change, some (like hot glue) through a physical change.
Is cutting up a pear a reversible change or a chemical reaction and why?
You can't glue together a divided pear,if you want it to be valuable but it is not a chemical change..why?-The reason is that a chemical change is followed by entirely new product and what you have done is to seperate the pear molecules,it is still a pear!,and it is a physical change,and you are free to ask more question,because I understand that a pear has life..
Is it correct to say the chemical changes are not reversible but physical changes are?
yes it is correct because chemical energy means you can't change something back like paper if you burned that paper you can't change it back but if you had that paper and you ripped it you can glue it back you can fix it that is physical energy when you can put something back together so yes you can say that.
Why does glue turn into slime when detergent is added?
When detergent is added to glue, it breaks down the glue's chemical structure and weakens its adhesive properties. This change in the glue's composition causes it to lose its cohesiveness and turn into a slimy consistency.
Is A glue gun melting glue is an example of a physical change?
Yes, a glue gun melting glue is an example of a physical change because the glue changes from a solid to a liquid without undergoing any chemical reaction.
Is glue a chemical or physical change?
Glue undergoing the process of drying and hardening is a physical change since its composition remains the same. When glue interacts with surfaces to form bonds, it is considered a chemical change as new substances are created.
Is making glue a physical or chemical change?
Making glue involves a chemical change as the components of the glue react to form a new substance with different properties. The mixing of ingredients and the formation of chemical bonds result in the creation of the glue.
When a glue gun melts a glue stick is it a physical change?
Yes, the melting of a glue stick by a glue gun is a physical change. This is because only the physical state of the glue stick changes from solid to liquid, but its chemical composition remains the same.
Is mixing elmers glue and liquid starch a chemical change?
No, mixing Elmer's glue and liquid starch is a physical change. A chemical change involves the formation of new substances with different chemical properties, while mixing these two substances does not result in a chemical reaction.
Is making glue an example of a physical or chemical property?
Making glue is a chemical process.
What is the chemical processesin adhesives?
Different for different adhesives. Hotglue for instance is merely a physical change while a 2-component epoxy glue undergoes a chemical change.
A glue gun melting glue is an example of what type of change?
Physical change because it is a solid to liquid. No change in the substance.
Is making goo from scratch a chemical change?
Chemical - reaction occurs when two components mix (ex. Acrylic polymers + polyurethane resins) or when external sources cause the reaction (i.e. heat or moisture). The physical nature of the components doesn't change, but chemically, a bond is formed.
Is drying of fevicol a chemical change or a physical change?
Drying of fevicol is a chemical change obviously !! Its because we cannot bring back the original properties of fevicol whatsoever we do to it !!! ---------------------------------------------------- But evaporation of solvents is a physical process.
Why is glue a chemical change?
Glues are not changes, but they are materials.
Why is adding borax solution to glue a chemical change?
When you mix borax solution with glue, a chemical reaction occurs where the borax molecules crosslink the polymer chains in the glue. This leads to the formation of a new substance with different properties compared to the original glue and borax solution, constituting a chemical change.
