The melting of an ice cube is considered both a physical change and a chemical change simply because a chemical change is something burning, so if the ice cube is cold and hot at the same time, it's both a physical change and a chemical change.
its physical change.to explain,the conversion of solid to liquid is physical
a chemical change is a change which brings about a change in the chemical properties of a substance which cannot be reversed through physical means like heating or cooling.
It is a physical change because when you have a chemical change it changes the properties and makes it into a new thing, and it can't be reversed. Physical changes are usually just changes of states (solid, liquid, gas) and a physical change can be reversed.
- Sublimation don't change the molecule; solid iodine or sublimated iodine are iodine. - Slaking of lime transform the calcium oxide in calcium hydroxide. A chemical change occur.
Deductive reasoning or if you work backwards it could be inductive reasoning.
It is physical. The wire changes shape, but it is still made of the same materials.
Copper has both chemical and physical properties. You will need to specify which property you are asking about
its physical change.to explain,the conversion of solid to liquid is physical
physical property happens by itself or from things in nature. chemical property happens by outside.
No.
both physical and chemical change occur
Chemical weathering is which makes new substances, whereas physical weathering is where rock is changed into smaller pieces of the same substance.
Breaking of stone is a physical or chemical change? Explain.
Both
It is a physical change because it is evaporation. Physical changes can be undone. If it was a chemical reaction it would be permanent like burning wood.
a chemical change is a change which brings about a change in the chemical properties of a substance which cannot be reversed through physical means like heating or cooling.
Changes from a to b and from b to c may be either physical or chemical.
