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. 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). :)
Lighting a match is not a physical change because it involves a chemical reaction that produces heat and light, resulting in the transformation of the matchstick. Drying wet clothes and cutting snowflakes from paper are physical changes because they involve a change in appearance or state of matter without altering the chemical composition of the substances.
Processes typically refer to actions or steps that occur in a system or in a series of events, rather than a specific property like physical or chemical. These actions can be driven by physical or chemical properties, but the processes themselves are not properties.
Lighting a match is a chemical change because the molecules in the matchstick undergo a chemical reaction when exposed to heat, resulting in the production of new substances like ash and smoke.
Yes, you can separate the parts of a mixture using physical processes such as filtration, distillation, sieving, and magnetism. These processes take advantage of the physical properties of the components in the mixture, such as size, shape, boiling point, or magnetic susceptibility, to separate them from each other.
No, rain turning to snow is a physical process, not a chemical reaction. It occurs when raindrops freeze as they fall through a layer of cold air near the Earth's surface, forming snowflakes.
Ignition of a match is a chemical process.

This is a physical phenomenon.
Melting snowflakes is a physical change, not a chemical change. The water molecules in the snowflake remain the same chemical composition before and after melting, they just change from a solid to a liquid state.
No, the noun 'snowflakes' is a concrete noun, a word for things made of a physical substance.An abstract noun is a word for something that can't be experienced by any of the five physical senses; something that can't be seen, heard, smelled, tasted, or touched. Snowflakes can be seen, touched, and even tasted (if you want).
lighting is a chemical change
have physical processes shape the landscape of Asia is by the WRONG TURN:(
Patterns in nature arise from the underlying physical and biological processes that govern natural systems. Examples include the branching of trees, the symmetry of snowflakes, and the spirals in shells. These patterns reflect efficiency in packing or growth strategies that have evolved over time.
The formation of snowflakes in a cloud is primarily a physical change rather than a chemical change. As water vapor in the atmosphere cools, it undergoes condensation and crystallizes into ice crystals, which then grow into snowflakes. This process involves changes in state (from gas to solid) but does not alter the chemical composition of the water molecules.
FALSE It is true the above answer is wrong
