Physical changes in matter are when physical properties are changed. Some physical properties are size and color. When a physical change in matter occurs, the material may have changed size (gotten smaller) due to weathering and erosion. Chemical changes are when the chemical composition of a substnce is changed. For example a chemical change would be iron turning into rust due to the process of oxidation
Examples: boiling of milk, preparation of milk powder.
Milk can also be a chemical change if the milk spoils.
Types of Physical Changes
changes in states of matter are physical changes, as they do not affect the chemical properties of the substance
A chaqnge of the state of matter is allways a physical change.
a physical is a change to a substance
the changes that matter undergoes are the physical and chemical change by:R.yu
no physical change does not change matter
no physical change does not change matter
Chemical composition
physical or chemical changes
When matter undergoes a chemical change, the composition of the matter changes. When matter undergoes a physical change, composition of the matter remains the same.
Physical changes.
Chemistry
The branch of physical science studies the properties of matter and changes in matter is known as chemistry. This is a branch which is mainly concerned with atoms and molecules and how they interact.
