Why changes of stat are physical changes?
Changes in state are physical changes because they involve a change in the physical appearance or state of a substance without altering its chemical composition. For example, when water changes from a liquid to a solid (freezing) or a gas (vaporization), it is still water chemically. This contrasts with chemical changes, which involve a rearrangement of atoms and result in the formation of new substances.
Are all physical changes accompanied by a chemical change?
A physical change is a change in chemical composition. A physical change is a change where chemical composition is not altered. Not all chemical changes are accompanied by a physical change, but some are. The same is true for the reverse.
How can a soda be a physical change?
A soda can undergo physical changes such as temperature changes causing condensation on the can, or changes in pressure leading to fizziness. These changes do not alter the chemical composition of the soda itself, making them physical changes.
When you heat up water and it changes to steam is it a physical or chemical change?
physical change because you are not doing anything to the object to change its ingredients or the way it is constructed and all you are really doing is adding heat.
How are physical and chemical changes alike and different?
The physical and chemical changes that occur in a system are alike because they change the state of the reactants. They are different because a chemical change produces a new substance while a physical change does not produce any new substance.Differ in physical:1. A difference in the appearance, smell, or simple display of a sample of matter without a change in composition.2. Be observed without changing the identity of the substance3. Can be seen or measured without changing a material.Differ in Chemical:1. There is a change of the substances in question2. determines how a substance changes into a completely different substance.3. Tells how the substance forms new substances when it mixes with something else.
How are physical changes alike?
all physical changes are alike in which all of them changing without changing in chemical makeup of the matter we have
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.
Are all physical changes are reversible changes?
Not all physical changes are reversible. Some physical changes, such as breaking a glass or cutting a piece of paper, are irreversible because they result in a permanent change to the material's structure. Reversible changes, like melting ice or boiling water, are changes that can be easily reversed by altering the conditions.
What undergoes physical change?
All substances have physical changes.
Are reversible changes and physical changes the same?
Reversible changes and physical changes are not exactly the same. Reversible changes can be undone and the original substance can be recovered, while physical changes alter the appearance or state of a substance without changing its chemical composition. Physical changes are usually reversible, but not all reversible changes are physical changes.
Is melting ice a physical change or chemical change?
Physical; all phase changes are physical changes because the composition does not change.
All changes in a phase are what?
the phases can be changed from a liquid, gas, or solid
What substances undergo physical change?
All substances have physical changes.
How are physical weathering and chemical weathering alike?
how are physical weathering and chenical weathering alike and different
How are chemical and physical weathering different and alike?
how are physical weathering and chenical weathering alike and different
Are all physical changes reversible with examples?
Not all physical changes are reversible because most times when such changes occur parts of the substance is lost to the environment.
