Which occurs more often on earth physical changes or chemical changes?
Physical changes occur more often on Earth compared to chemical changes. Physical changes involve alterations in the state or appearance of matter without changing its chemical composition. Examples include changes in shape, size, or state of matter (solid, liquid, gas). Chemical changes involve the formation of new substances with different chemical properties.
Are the changes in the state of matter chemical changes?
No, changes in state of matter (such as melting, freezing, boiling) are physical changes, not chemical changes. Chemical changes involve the formation of new substances with different chemical properties.
Differences between physical changes and chemical changes?
Physical changes are changes that affect the form of a chemical substance, such as changes in state or shape, without changing its chemical composition. Chemical changes, on the other hand, result in the formation of new substances with different chemical properties. Physical changes are usually reversible, while chemical changes are often irreversible.
Changes in properties of matter are called?
physical or chemical changes
Are chemical changes irreversible If yes then what about the chemical reactions that are reversible Don't we say that all chemical reactions are chemical changes?
some chemical changes can be reversed but they are hard to reverse usually
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 properties are seen when one substance changes to another known as?

Are all physical changes accompanied by chemical changes?
Not all chemical changes are accompanied by a visible physical change. Most chemical changes however will be accompanied by a physical change.
What part does heat play in most chemical changes?
Heat usually accelerates any chemical changes
What can be used as an indicator fot a physical change and a chemical change?
A temperature change can be seen both in physical and chemical changes.
Can anyone summarise the physical processes long answers needed please?
Physical processes is changes that can be seen from the eye. These changes affecting the form of a chemical substance but does not change its chemical composition.

Which equipment is most useful when measuring the chemical and physiacl environmental changes?
Sensors of varying nature can measure the physical and chemical changes in the Environment. At present, there are no instruments that can measure both physical and chemical factors.
What are the type of changes in baking a cake?
The most important changes are of chemical nature; water evaporation is a physical process.
What are the different chemical changes in food?
I am also researching on this. Cant seem to find answers anywhere. I am also researching on this. Cant seem to find answers anywhere. There is the formation of a precipitate seen when baking a cake or making eggs. A color change indicative of chemical changes can be seen in the browing of meat or potatoes. Hope this helps.

What are the chemical and physical changes of photosynthesis?
There are no physical changes. there are only chemical changes.
