A physical change is a change of state that does not affect the properties of the substance. Example: Ice melting to water. It's still water, just in a different form.
A chemical change is a change of properties in a substance, which creates* a new substance. This happens when two substances combine. Example: Lighting a peice of paper on fire. When this happens, the fire and the paper put together creates ash.
*Note: You can not create or destroy mass, only change it. Example: If the paper weighed 1 g before it's burning, it will weigh the same after.

Is slicing an onion a chemical change or a physical change?
Chopping an onion is considered to be a physical process. Chopping an onion is not a chemical process because it does not change the chemical composition.
Is melting ice cubes physical or chemical?
It is PHYSICAL because when the ice cubes melt, they turn into water. We can reverse the change and bring the water back into ice. Water has a chemical formula of H2O and so does ice. So, Physical Change: can be reversable, the object's components don't really change.
What takes place when a substance undergoes a chemical change?
well the way i learned it, if you cannot bring something back to its original state its a chemical change. if you can, then its a physical change.For example-burning paper is a chemical change because you cannot bring that piece of paper back from the ashes.wrinkling paper is a physical change because you can unwrinkle the paper and bring it back to its original state.

Bile will bring about a chemical change to fat. This is because bile chemically alters the way the fat is structured.
Is drying of fevicol a chemical change or a physical change?
Drying of fevicol is a chemical change obviously !! Its because we cannot bring back the original properties of fevicol whatsoever we do to it !!! ---------------------------------------------------- But evaporation of solvents is a physical process.

Chemical change from solid to liquid?
Not exaclty... A chemical change is anything that changes the chemical compound... Example... Water avaportating.... A physical Change is just changeing apperance... Example... Ripping a piece of paper Its still paper right?... ^wrong, im in grade nine and even i know that's wrong. water evaporating* is completely a physical change. a chemical change is a change that you cannot change back and diffrent particles are chemically combined. for example cooking a pancake, there is no way to make that pancake back into the the powder and water again, it is irreversable. a physical change is something that can be reversable and it isn't just changing appereance it can be changing states as well, water evaportating is a physical change because the vapor can be turned back into the liquid water, as well as water freezing into ice is a physical change because you can melt it and bring it back to its origanal state. you can have solid precipitate forming out of liquids for example potassium iodine mixed with lead nitrate will give you a yellow liquid with white flakes called solid precipitates.
