Physical Change is any change made to a substance without changing its chemical composition. For example, cutting iron or heating clay. when i cut iron i am still left with iron, when i heat clay, all i have is solid clay. i didn't change their chemical compositions
Physical change is changing it in appearance or mass, but not chemically. For example an example of physical change would be to cut a piece of paper in half as you do not change its chemical composition, this is as opposed to burning the paper, which would change it chemically.
A chemical change cannot usually be reverted due to the alteration of molecular formations within a substance. Cooking a raw vegetable can be treated as a chemical change because the process cannot be reverted, unless the object can spontaneously quantum tunnel to an earlier stage of itself, or there is technology capable of increasing the probability of such phenomenon.
A physical change on the contrary is a reversible change which usually involves a transfer of energy to or away from the substance or object in question. Freezing some water contained in a beaker may serve as an example, as supplying sufficient thermal energy to the ice that forms will revert the ice back to its original liquid water state.
A physical change is a change in the physical properties of a substance without a change in its chemical composition.Physical change is usually reversible and temporary.

the change of matter are the physical and chemical change physical change is a substance that do not change. chemicalchange is a substance that change. examples of physical: crumpling of paper evaporation of liquid examples of chemical: digestion of food burning of wood
please explain how has science have impact our every day lives give five examples
There is nothing to change no color change so it is a physical change
no
give examples of physical and chemical change
Please see related question
There are quite a few examples of physical change including melting ice. You can also consider freezing water and boiling water a physical change.
1. breaking a rock in half 2. ripping a piece of paper

give at least 3 examples of technology
It causes matter to change by turning water into gas which is vaporization. water into ice and burning wood into ash.
Explain how turn around Management can be used for bringing change in organisations. Give examples.
give me 50 physical changes and 10o chemical change
distress=death and childbirth
I don't now
The physical properties of the material are changed; example - water: ice, liquid water and water vapors have very different properties but the same chemical formula.
