When a chemical reaction takes place, usually burning and fizzing are seen.

∙ 14y agoA chemical change is usually changing something at the chemical level
e.g: rusting, burning, etc.
A physical change is usually changing the physical appearance of an object
e.g: breaking glass, tearing a piece of paper in two, etc.

∙ 13y agothe most important thing to cause a chemical reaction to occur is activation energy,& the reactants should posses minimum energy taht is threshold energy.
The answer to the science worksheet is: Collisions.

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 a physical change in matter?
A physical change is a change that affects one or more properties of matter. For example, if you have a popsicle and it melts, it's looks change but the physical properties don't
A physical change occurs when matter changes state?
no physical change does not change matter
Does a physical change occurs when matter changes state?
no physical change does not change matter
What are the changes that matter undergoes?
the changes that matter undergoes are the physical and chemical change by:R.yu
Does changes in a state of matter involve a physical change?
A chaqnge of the state of matter is allways a physical change.
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
What are two kind of changes in matter?
The two types are chemical and physical changes.
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.
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
