What does not change when a substance changes matter?
The chemical composition of the substance does not change when it changes its state of matter. The arrangement of atoms and molecules may vary, but the elements present in the substance remain the same.
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 changes in the state of matter are physical chemical or neither?
Changes in the state of matter are physical because they involve a change in the physical properties of a substance, such as its shape, volume, or density, without altering its chemical composition. Examples include melting, freezing, evaporation, and condensation.
Chemical changes can be reserved by physical change?
No, chemical changes cannot be reversed by physical changes. Chemical changes involve the formation of new substances with different properties, while physical changes only affect the state or appearance of a substance without changing its chemical composition. Once a chemical change occurs, it cannot be undone by a physical change.
What can indicate a physical or chemical change?
Physical changes can be indicated by changes in appearance, texture, size, or state of matter without altering the chemical composition. Chemical changes, on the other hand, can be indicated by the formation of new substances, changes in color, temperature, odor, or the production of gas.
What are physical and chemical?
physical changes do not change the chemical properties of a substance
What is the diffence between physical and chemical properties as well an physical and chemical changes?
Physical properties can be observed without changing the chemical composition of a substance. Chemical properties can only be observed by changing the chemical composition of the substance. In a physical change, the chemical composition of the substance does not change. In a chemical change, the chemical composition of the substance changes.
What is the diffeference between a physical and a chemical change?
A physical change is when a substance changes, but still keeps its identity. When a chemical change occurs, the substance changes its identity.
When a physical changes occurs a substance's changes?
A new substance is formed only after a chemical change.
Is it a physical or chemical change when a substance changes form but it remains the same substance?
it would be physical change because physical change is when the substance stays the same
Are there changes in the chemical changes of a substance when it undergoes a physical change?
nada
Is Melting does that changes as a physical or chemical?
It is a physical change because the chemical composition of the substance does not change.
How can you causes physicals change?
Physical changes are changes affecting the form of a chemical substance, but not its chemical composition.
Is reacting a physical change or chemical change?
Reacting can involve both physical changes and chemical changes. Physical changes involve alterations in the physical state of a substance without changing its chemical composition, while chemical changes involve the formation of new substances with different chemical compositions.
Do chemical changes affect the chemical structure of a substance?
Yes, chemical changes result in a change in the chemical structure of a substance. During a chemical change, new substances with different chemical compositions are formed through the rearrangement of atoms and bonds. This is in contrast to physical changes, where the chemical structure remains the same even though the physical properties may change.
When a substance changes from one physical form to another you say the substance had had an?
Chemical reaction
Is phase changes physical or chemical?
Phase changes are physical changes, not chemical changes. They involve a change in the state of matter (solid, liquid, gas) without altering the chemical composition of the substance.
