there's many many diffrent types of physical and chemical changes too.There's so many nobody really knows how many there are.But of course the is way to many to count on our hands.we'll never really know.See the thing is they happen everyday.so that's the answer to your question no scientist or anybody will every find out .
There are lots your can make up heaps....a physical change is a change that is reversible..thats all i guess..! There are lots your can make up heaps....a physical change is a change that is reversible..thats all i guess..!
What else can I help you with?
Are phase changes physical or chemical in nature?
Phase changes are physical changes in nature. They involve a change in the state of matter (solid, liquid, gas) rather than a change in the chemical composition of the substance. Heating or cooling a substance can trigger phase changes.
What are the differences between a congruent and incongruent phase transformation?
A congruent phase transformation occurs when a single phase changes into another single phase with the same composition. An incongruent phase transformation happens when a single phase changes into multiple phases with different compositions.
What phase does water change to when boiled?
Water changes from a liquid phase to a gaseous phase when it is boiled.
When a substance changes from one physical form to another you say the substance has had a what?
When a substance changes from one physical form to another, you say the substance has had a phase change or undergone a phase transition.
What changes take place when a substance goes through a phase change?
During a phase change, the arrangement of the particles changes while the chemical composition remains the same. Energy is absorbed or released, causing changes in temperature and state. Phase changes include processes like melting, freezing, vaporization, condensation, and sublimation.
Why phase changes are reversible'?
Phase changes are accompanied with optical contrast and therefore the feasibility of phase.
What are phase changes?
its physical changes
Why is a phase change only a physical change?
See "Related Questions". Phase changes are reversible by adding or subtracting heat. In many cases chemical changes are not easily reversed.
Phase changes are examples of what changes?
Puberty
What are changes in phase physical changes?
Because it changes its form.
Explain why a phase changes are a property of an atom?
Because atoms only go through phase changes
What phase changes require the addition of energy?
Phase changes requiring the addition of heat energy are the phase changes from solid to liquid, liquid to gas, and solid to gas. These phase changes are termed melting (solid to liquid), evaporation (liquid to gas), and sublimation (solid to gas).
Are phase changes physical or chemical in nature?
Phase changes are physical changes in nature. They involve a change in the state of matter (solid, liquid, gas) rather than a change in the chemical composition of the substance. Heating or cooling a substance can trigger phase changes.
Are phase changes in chemistry physical changes?
YES
What changes directly from a solid phase to a gas phase?
sublimation
Phase changes are not associated with a change in?
Phase changes, such as melting or freezing, are not associated with a change in temperature. Instead, the energy associated with phase changes is used to break or form intermolecular forces between molecules.
What are the differences between a congruent and incongruent phase transformation?
A congruent phase transformation occurs when a single phase changes into another single phase with the same composition. An incongruent phase transformation happens when a single phase changes into multiple phases with different compositions.
