A physical change in matter occurs when the shape or form of matter changes, but there is no chemical reaction. If someone were to melt a sugar cube, that would be an example of a physical change.

What are the changes that can be reversed?
example of change can be reversed
Is combustion a physical change?
NO its a chemical change for it can't be reversed
What is a the difference between a chemical and physical change?
A physical change can be reversed such as an ice cube melting. A chemical change, on the other hand, cannot be reversed such as burning wood.
Can a physical change always be reversed?
No, not always. But mostly.
What kind of change is it if changing from one state of matter to another?
it is a physical change since it can be reversed to its original form.

What is physical change in matter?
A physical change is a change to a substance/object which can be easily reversed, and no new substance is formed from it (as opposed to chemical change). The state of matter is usually changed, for example, turning from a solid to a liquid. e.g. ice cube melting
What is the difference between physical and chemical changes of matter?
Usually a physical change can be reversed such as fruit rotting. where as chemical change is very hard to reverse such as rust
What are example of a physical change that can be reversed and an example of a physical change that cannot be reversed?
an example of a physical change that can be reversed is like freezing water and letting melt back into water again
Is combustion a physical change?
NO its a chemical change for it can't be reversed

Burning is what form of change?
it is a chemical change because it cannot be reversed
Can a physical change always be reversed?
No, not always. But mostly.
What changes of matter occur in respiration?
A change is said to be physical if no new substances are formed. Physical changes are temporary and can easily be reversed to give back the substances in their previous form. Freezing of water is an example of a physical change. A change is said to be chemical if new substances with different properties are formed. Chemical changes are permanent and cannot be reversed to give back the substances in their previous form. Burning of paper is an example of a chemical change.
How is sour milk a chemical change?
milk going sour is a chemical change because it can't be reversed. Most physical changes can be reversed for example snow melting is a physical change because it can freeze again.
What kind of change is it if changing from one state of matter to another?
it is a physical change since it can be reversed to its original form.
Is an egg a chemical change?
Yes, it is, because it cannot be reversed.
