a physical change will only alter the appearance but will NOT change the substance to another substance =)
It is considered a physical change. A chemical change involves chemical reactions that change the substance into another substance. A physical change typically only modifies the form or phase.
Colorless is a physical property. Determining change requires you to compare two things.
The heat conductivity of a substance does not involve changes to its chemistry. Heat conductivity is a physical change and characteristic to a substance.
change in the form -in general can be indicated for the physical form. The substance may dissolve or its stage may change. If the change is physical, it should be reversable.
Physical because it is still Oxygen. A chemical change results in a chemical equation and thus a new substance. No new substance = no chemical change. Liquefaction is a physical property.
a physical change is a change in any physical property of a substance, not in the substance itself
a physical change is a change in any physical property of a substance, not in the substance itself
it would be physical change because physical change is when the substance stays the same
it would be physical change because physical change is when the substance stays the same
it would be physical change because physical change is when the substance stays the same
No. The whole idea of a physical change is one which does not alter the nature of the substance.
If form changes but identity doesn't change then it is a physical change.
No. The whole idea of a physical change is one which does not alter the nature of the substance.
No.
A physical change occurs when the composition of a substance does not change. This means the substance retains its chemical identity but may undergo a change in its physical properties like shape, size, or state of matter. Examples include melting, freezing, boiling, or dissolving.
A physical change does not change the substance.
no, if it's a substance change then it's a chemical change. If it were a physical change then it would be the same substance
