When matter changes states a physical change occurs what is needed to make this change happen?
When a chemical reaction takes place, usually burning and fizzing are seen.

What are two kinds of changes that occur in matter?
The two types of changes in matter that it goes through is physical change and chemical change... trust me, we are learning this at school.
What are signs a physical change has occured?
change in the form -in general can be indicated for the physical form. The substance may dissolve or its stage may change. If the change is physical, it should be reversable.
Is water condensing a chemical change?
No, it is a Physical Change. Physical Changes are concerned with energy and states of matter. A physical change does not produce a new substance. Changes in state or phase (condensation, melting, freezing, vaporization, sublimation) are physical changes. Other examples of physical changes include crushing a can, melting ice, and breaking a bottle. Chemical changes take place on the molecular level. A Chemical Change produces a new substance. Some examples of chemical changes include combustion (burning) and rusting of a metal.
What is a permanent change?
In science change is nothing but the transfer of a matter or mixtures of matters from one state to another. Here the physical 'state' is not a matter, it may change or not. Permanent change of a matter is also a change of matter which wont regain its previous state. Burned paper is an example for permanent change and vapourisation of water is a temporary change. we can classify the changes(either physical or chemical) according to the changes whether it is permanent or temporary.
What is the importance of physical change?
The importance of physical change is that :-1) No new substance is formed.2) It is a temporary change.3) It is easily reversible.4) Very little heat energy is absorbed or given out.The mass of a substance does not alter in a physical change.
A physical change occurs when matter changes state?
no physical change does not change matter
How do chemicals differ from physical 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.
What is physical and changes in matter?
a physical is a change to a substance
Can matter change states after a physical change?
Yes, matter can change states after a physical change. Physical changes involve changes in the arrangement of particles without altering the chemical composition. For example, melting ice (solid to liquid) and boiling water (liquid to gas) are physical changes that involve changes in state.
Does a physical change occurs when matter changes state?
Yes, a physical change occurs when matter changes state. This change is reversible and does not alter the chemical composition of the substance. Examples include melting, freezing, vaporization, and condensation.
What is changes in physical change?
physical change is change in the physical properties of matter that does not involve a change in its composition
What properties of matter are affected by physical changes?
The properties of matter that are affected by a physical change is for example, there is a house then it gets destroyed that is a physical change.
When Matter changes how it look but not what it is made of?
It is a physical change.
How does Matter Change Physical Changes?
It affects it state.
What is it called when matter changes?
Physical change, if it changes in a way to be seen, or chemical change, which if the change can not be seen
What is a physical change of matter?
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 phisycal changes in matter?
Physical changes are changes that only change the appearance of an object, but not the type of matter. For example, if a metal bike rusts the bike will still remain a solid. That is a physical change.
