Is sewing fabric together a chemical or physical change?
Answer. Answer: It’s physical change since the chemical nature of the fabric has not changed .
Is dying at shirt a chemical or physical change?
A: The dyes are called fiber-reactive. That means a chemical reaction takes place between the dye molecules and the fabric molecules. The dye bonds with the cotton and actually becomes a part of the fabric. That is why the dyes are so permanent and vibrant even after several washings.
Which of the following is a physical change?
A change in physical properties is called a physical change. Physical changes do not alter the identity of a substance. Pounding, pulling, cutting, dissolving, melting, or boiling do not produce a new substance with new properties, so they are all physical changes.
Is dying a cloth a physical change?

What are 5 examples of physical change?
Examples of physical change include changes in the size or shape of matter. Changes of state—for example, from solid to liquid or from liquid to gas—are also physical changes. Some of the processes that cause physical changes include cutting, bending, dissolving, freezing, boiling, and melting.
What are 3 examples of physical properties?
Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity. We can observe some physical properties, such as density and color, without changing the physical state of the matter observed.
Is salt water evaporating a chemical change?
Evaporation of salt water is a physical change.
Is toasting bread a chemical change?
A chemical change breaks apart or rearranges the atoms or molecules of the object, resulting in a new substance. Toasting the bread and digesting the toast are both examples of chemical changes.
