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.
Melting and welding of glass are physical processes.
Physical. The shape changes, but it is still only glass. When the rain rusts your bicycle, that's a chemical change.
A chemical change because the chemicals from the bee's stinger are reacting with the chemicals in your body, producing the red mark.
chemical change.because once the tray melts it's no longer there anymore
It is chemica changel because it produces gas and the smoke it produce is one of the evidence that it is really a chemical change, also you can't put it back to its beginning state.
Chemical broooooooooooooooo niga
Chemical I think
Physical.
NO{dmn
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.
This is a chemical change because a chemical reaction occurs, creating a whole new substance (carbon dioxide).
Physical
A chemical change because the chemicals from the bee's stinger are reacting with the chemicals in your body, producing the red mark.
Physical, because you are only diluting the tea, but not creating a new substance.
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.
No because combustion is a chemical reaction. Anything having to do with burning undergoes chemical change. This creates a new substance therefore creating a chemical change.
