How matter changes state-?
With the help of some physical and chemical processes matter changes its state. Like using heating , cooling etc we can change the state of 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.
Is candle wax melting exothermic?
no because when a substance changes its state of matter then it is NOT considered a chemical reaction or a chemical change.
What are the changes that matter undergoes?
the changes that matter undergoes are the physical and chemical change by:R.yu
What are three things that are often indications of chemical changes?
Chemical changes can be identified by 1. Color change 2. Fizzing 3. Temperature changes 4. Odor changes 5. Change in the state of matter (solid, liquid, gas)
Are changes in the state of matter are physical chemical or neither?
changes in states of matter are physical changes, as they do not affect the chemical properties of the substance

When matter changes state what is a chemical property?
covalent bonds
Are bateries chemical changes?
Yes. Chemical changes are changes in what things are made of, physical changes are changes of physical localization or state of matter ( liquid, solid, or gas)
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.
When matter changes state what two things are always conserved?
Mass and chemical composition
What is 3 changes that are physical changes?
Evaporation, Condensation, Melting and Freezing are all physical changes as only the state of matter is changing, rather than the chemical properties.
Heat causes physical changes in matter by changing?
Typically heat changes the STATE of matter from solid to liquid to gas.However, heat can also cause chemical changes for example combustion.
Is candle wax melting exothermic?
no because when a substance changes its state of matter then it is NOT considered a chemical reaction or a chemical change.

How does a chemical change affect the composition of matter?
chemical change = chemical reaction. ( the composition of matter always changes). In a chemical change the matter in one thing changes, for example you will know a chemical change has occurred when the color or odor has changes or when a new gas is given off.
What are three things that are often indications of chemical changes?
Chemical changes can be identified by 1. Color change 2. Fizzing 3. Temperature changes 4. Odor changes 5. Change in the state of matter (solid, liquid, gas)
