A physical change; you're turning the solid glass into a semi-liquid molten state, forming it into a desired shape, and then allowing it to cool and harden.
The process of bees creating wax from sugar is a physical change. It involves the physical transformation of the sugar molecules into wax molecules without any change in the chemical composition of the substances.
It is as irreversible change, so it is chemical.
Pulverizing sugar is a physical change because it does not alter the chemical composition of the sugar molecules. Grinding the sugar only changes its physical state by breaking it down into smaller pieces without creating any new substances.
A physical change because you are not changing the properties of the towel.If you burned it that would be a chemical change because it would no longer be in its original form.
NO!They are attracted to the North and South Poles.
Physical.

No, this is a physical change. Although you melt the glass, the molecules are not transformed into another type of molecule.
chemical
Dissolving is a physical change.
Physical because, the lemonade dissolves into the water, without creating any of the chemical changing results.
The process of bees creating wax from sugar is a physical change. It involves the physical transformation of the sugar molecules into wax molecules without any change in the chemical composition of the substances.
This is a chemical change because a chemical reaction occurs, creating a whole new substance (carbon dioxide).
Physical
Physical as H2O and some other elements are only removed from the perfume istead of creating new substances Physical, because H2O and other chemical substances are removed instead of new chemical substance being created.
Physical, because you are only diluting the tea, but not creating a new substance.
Mashing a banana is a physical change because it does not alter the chemical composition of the banana. The act of mashing simply changes the physical appearance and texture of the banana without creating any new substances.
