There are a few physical changes that take place during digestion. Chewing food to reduce the size of the pieces and also gives the enzymes and other things more space to act on. Another is churning which is found in the stomach. Here the food is moved around somewhat like what happens in a mixing bowl. And the last is peristalsis which is a physical movement seen in the tract from the esophagus to the anus.
This is a physical change. There is nothing that changes the components of either the diamond or the glass when the diamond is used to scratch glass.
They are called digestive enzymes. There are many that are used in the process, beginning in the mouth with enzymes that begin the break down of starches.
The first digestive juices are those produced in saliva that is excreted into the mouth.
The question is a bit vague, since a PID changes with every process, and any user may be attached to that process. Please clarify what you are asking.
Papermaking is a series of physical and chemical changes. The physical and chemical changes will depends on raw material used and grade of paper manufactured. For a typical north American paper mill which uses wood for making copying paper, following changes will take place.

Yes. Among its many functions, it produces bile.
Biological evolution is the change of animal and plant life over time. Biological evolution is used to explain changes in finch beaks for example.
This is a physical process.
Heat is measured using calorimeter.A calorimeter is an object used for calorimetry, or the process of measuring the heat of chemical reactions or physical changes as well as heat capacity.
The main purpose is to take water back in from the digestive process. Some vitamins are also absorbed through this process.
The digestive system begins at the mouth where teeth are used to break and grind up food and carbohydrate digestive enzymes begin the process of digesting carbohydrate. Jerry Hart, MS. College Instructor in Nutrition
A fish has intestines that are used to digest its food in a similar manner to the digestive process of other animals.
