Is drying of clothes on a line a chemical change?
Drying wet clothes is a physical change because the clothes are same as it got dried from removing water content. Physical changes only change the appearance of a substance, not its chemical composition.
Is something drying out a chemical or a physical change?
Physical changes affect a substance’s physical properties but do not alter its chemical structure. Types of physical changes include boiling, clouding, dissolution, freezing, freeze-drying, frost, liquefaction, melting, smoke and vaporization.
What type of change is drying wet clothes?
Drying wet clothes is a physical change because the clothes are same as it got dried from removing water content. The composition is same nothing has been changed. Physical changes only change the appearance of a substance, not its chemical composition.
Is washing clothes a chemical or physical change?
Chemical action – This is the reactions between the soap, soil, and water to remove stains from clothing. For washing purposes, a chemical is the cleaning agent that is added to the water. Saponin, the cleaning agent in soap nuts and our liquid detergent is a chemical – it’s just made by a plant instead of by people.

- Burning of paper and log of wood.
- Digestion of food.
- Boiling an egg.
- Chemical battery usage.
- Electroplating a metal.
- Baking a cake.

- Various metabolic reactions that take place in the cells.
What evidence shows chemical changes?
Some signs of a chemical change are a change in color and the formation of bubbles. The five conditions of chemical change: color change, formation of a precipitate, formation of a gas, odor change, temperature change.
Is evaporation a physical change?
Melting, evaporation and condensation are examples of physical change, or change of state, and are distinct from changes that cause new materials to form through a chemical reaction. Some curricula talk of physical changes as being reversible, and chemical change being irreversible.
What are physical and chemical changes?
In a physical change the appearance or form of the matter changes but the kind of matter in the substance does not. However in a chemical change, the kind of matter changes and at least one new substance with new properties is formed. The distinction between physical and chemical change is not clear cut.
What are the 5 examples of chemical change?

- Rusting of iron in presence of moisture and oxygen.
- Burning of wood.
- Milk becoming curd.
- Formation of caramel from sugar by heating.
- Baking of cookies and cakes.

What causes drying of clothes?
When a wet object dries, it is because the liquid water that is on the object evaporates to water vapor and diffuses out into the air. Drying consists of individual water molecules breaking free of their bonds to each other and to the object, and then flying out into the air.
Is drying wet clothes a chemical change or physical change?
The person earlier said drying wet clothes, but he/she is wrong because when you dry wet clothes, the water goes through a physical change called evaporation, which is NOT a chemical change. I hope this helps. Good luck on your chapter assessments(I’m doing mine too).
How does temperature affect the drying time of a cloth?
The highest curve, indicating the slowest drying rate, was obtained by heating the cloth to ambient temperature, with no deliberate air flow over it. The water vapour enters the boundary layer just above the cloth, but disperses very slowly into the room air.
What are some examples of physical changes?
Physical change – Inflating a balloon , Dissolving of sugar into water , Dissolving of salt into water , Drying of wet clothes and hair , Stretching of a rubber band , Melting of ice and butter , Clothes being ironed , Wool being knitted into a sweater.
Is lighting a match a physical or chemical change?
The answer is lighting a match box because when doing so, the match goes into flames and flammability is a chemical change. When cutting a snowflake, the substances do not change, neither does it change when drying wet clothes.
