Both the stretching and the breaking are physical changes.
Weathering is the term used to describe the reduction in the size of a rock by chemical or physical means.
Weathering can involve both physical and chemical changes. Physical weathering breaks down rocks into smaller pieces without changing their chemical composition, such as through freezing and thawing. Chemical weathering, on the other hand, alters the chemical makeup of rocks through processes like oxidation or dissolution.
Digestion is a chemical process that breaks down food particles into smaller molecules through the action of enzymes. It involves the breakdown of complex molecules into simpler ones through chemical reactions.
It would be easier to say how they are different. Both physical and chemical weathering can cause pitting, erosion of material and degradation of optical properties, making glass surfaces less reflective or transmissive.
The process of bile is a physical one because it does not contain any enzymes that breaks down any fats. Lipase is the enzyme that breaks down fats but bile is only an emulsifier, which is a physical process, that combines bile with the fats.
It is a physical phenomenon.
no its a physical change

Weathering is the term used to describe the reduction in the size of a rock by chemical or physical means.
It is a physical change. There are no changes made to the compounds in a pencil by breaking it.
Physical weathering is breaking down of rocks by weather that does not change their chemical components. Chemical weathering is weathering that breaks rocks down by a chemical change.
Weathering can involve both physical and chemical changes. Physical weathering breaks down rocks into smaller pieces without changing their chemical composition, such as through freezing and thawing. Chemical weathering, on the other hand, alters the chemical makeup of rocks through processes like oxidation or dissolution.
it would be a chemical reaction mArKe ^_^
Digestion is a chemical process that breaks down food particles into smaller molecules through the action of enzymes. It involves the breakdown of complex molecules into simpler ones through chemical reactions.
The dissolving of sodium hydroxide in water is a physical change because no new substances are formed. Sodium hydroxide breaks down into its ions in the water, but its chemical composition remains the same.
When a carrot is cooked, it undergoes a chemical change because the heat breaks down the molecules within the carrot, altering its chemical composition. This results in changes in color, texture, and flavor, which are characteristics of a chemical change.
It is a physical change. The resulting fragments of glass are still glass and of the same composition.
