Is drying wet laundry a chemical change?
Drying wet clothes is a physical change because the clothes have not changed composition and have not turned into something else.
Is drying a physical or chemical change?
DRYING OF CLOTHES IS A PHYSICAL CHANGE BECAUSE IT DOES NOT NOT INVOLVE THE CREATION OF A NEW SUBSTANCE RATHER IT INVOLVES REMOVAL OF WATER FROM CLOTHES. SINCE NO NEW SUBSTANCE IS FORMED AND THERE IS NO LOSS OR GAIN OF ENERGY, IT IS A PHYSICAL CHANGE.
What type of change is drying of wet clothes give reason?
Is washing clothes a chemical change?
Answer: chemical. Explanation: since washing clothes involves the removal of the germs and other stains, those chemicals or other stains can’t be recovered anyways,hence it is more likely to be a physical change and as well as a chemical change because of the washing powder used.
How do wet clothes dry up?
Condensation: It is the process in which the gaseous state of a substance is converted into liquid state. So in this question as wet clothes are dried up so liquid is converted into gas. Hence it is Evaporation which is happening. Hence the correct option is (A).
Which phenomenon occurs during drying of wet clothes?
Evaporation
Evaporation is a surface phenomenon. Water from the surface of the clothes gets evaporated. Thus, evaporation occurs during drying of wet clothes.
What is the chemical reaction in washing clothes?
Detergent cleans by causing a chemical reaction with water to force dirt and debris out of clothing. Detergents work with water to loosen the dirt trapped in the material of clothing and clean them away. The detergents are alkaline in nature. They chemically react with the dirt or oil or stains.
Why is washing a chemical change?
When water, soap, and a dirty surface are combined, a chemical reaction happens. The hydrophobic end is afraid of the water and stays by the dirt and begins attacking the dirt. The hydrophile end is afraid of the dirt and stays by the solvent, allowing a place for the attacked dirt to be released.

Which phenomenon occurs during the following changes a formation of clouds B drying of wet clothes C wax melts in the sun?
Therefore, phenomenon for formation of clouds is known as condensation. Drying of wet clothes is a phenomenon called vaporization as liquid state of water changes into gaseous state. When wax melts in the sun then this phenomenon is called melting.
Why are wet clothes not a chemical change?
Drying wet clothes is a physical change because the clothes have not changed composition and have not turned into something else. They just merely have gone from being wet to dry. This is not a chemical change because the clothes still are made of the same material and are not something different from what they originally were.
Is the drying of hair a physical or chemical change?

How does the process of drying cloth take place?
Drying cloth involves two processes. Energy has to be provided to change the water from liquid to vapour and an air stream is needed to remove the vapour. We discuss the two processes separately and then describe an experiment which demonstrates their relative importance.
