A physical change is reversible?
Well it is in some cases, for exampleMelting of iceIt is a physical and a chemical changeBUT, some physical changes likeCutting of fruitsIt is a physical and irreversible change-----------------------------------------------------------------------------------------------------SO my answer would be (as I said earlier) in some cases
What is are some examples of a physical change?
Melting of ice, boiling of water, tearing a piece of paper, and breaking a glass are all examples of physical changes. These changes do not alter the chemical composition of the substances involved, they only involve a change in their physical appearance or state.
What are things that have physical changes?
Water because It is first solid its ice then when it melts it is liquid and when it is a gas its water vapor.
How does changes occur in the different changes of matter?
Changes in the states of matter occur through processes like melting, freezing, condensation, vaporization, and sublimation. These changes involve the rearrangement of particles at the molecular level due to changes in temperature or pressure. During these transitions, energy is either absorbed or released.
What are some good effects of physical change?
Some good effects of physical changes: Material or substance remains unchanged, Castings, Sculptures, Shaping of metals, Shaping of stones for building, Polishing of metals and stones.

How is physical change and chemical change different?
A physical change is when some thing's shape or volume is changed. But a chemical change is a reaction between two or more objects to create something new and you can't get back what you originally started with.
Are all physical changes accompanied by a chemical change?
A physical change is a change in chemical composition. A physical change is a change where chemical composition is not altered. Not all chemical changes are accompanied by a physical change, but some are. The same is true for the reverse.
Can you reverse physical changes?
Physical changes, those changes that do not involve chemical changes or nuclear changes, can be reversed, though doing so may be difficult in some cases. To cite a single example, water can be frozen and then thawed. Or it can be boiled off and then condensed.
What are the differences between the physical and chemical?
in changes. Physical changes can be reversed. E.g. if you were to melt a block of ice, and then freeze it again, it would to some degree be reversed. This is a physical change. However, if you were to burn a peace of toast, the change would be chemical. Once the toast is burnt you cant get it back.
Do all changes involve interaction?
No, not all changes involve interaction. Some changes can occur independently without any external influence or interaction. For example, changes in an inert object's state or changes in a closed system can happen without any interaction with the external environment.
What is the meaning of physical technology?
Physical technology is the technology focused on the physical matter or creating inventions. Bicycles, smart roads, air travel, nano tech, and roller coasters are some of the examples of physical technology.
What are some physical changes of hydrogen?

What were some inventions that brought about major changes in the way people lived in the late 1800's and early 1900's?
The invention of the steam train is one of the inventions that brought major changes in the lives of people in the late 1800's and early 1900's.
Is cooking a physical or chemical change?
Cooking involve chemical reactions.
