This is a chemical change, a photochemical reaction.
Physical change reason being it is
Yes this is a physical change because they are melting it and then it's being changed by the heat of the torch but heat is a physical change.
A can being crushed is definitely a physical change. Same properties, just a different shape!
Applying makeup is a physical change, not a chemical change. It involves rearranging or altering the appearance of the substances (e.g., pigments, powders) on the skin without changing their chemical composition.
hammering a nail is a physical change, this is because the nail changes shape from being long to being short and in a board for example.
The color of the sky being blue is a physical property, not a physical or chemical change. It is due to the scattering of sunlight by the Earth's atmosphere, particularly by air molecules and small particles in the atmosphere.
A physical change in a tennis ball could be flattening or deformation from being hit or squeezed. Another physical change could be discoloration or fading of the ball's outer fabric due to exposure to sunlight or wear and tear.
It is a physical change because the sun's rays create a physical differential not chemical relates to chemical change ie: the ice tea crystals dissolve in the water. --------- Chemical change, because fading in this case is the result of a photochemical reaction.
Flat tires is a sign of physical change. The tires go from being normal, to then being flat. This changes their physical form.
physical change plain and simple
A faded picture is considered a chemical change. This is because the fading process typically involves a chemical reaction between the light-sensitive compounds in the photograph and light exposure, leading to a permanent alteration of the molecular structure and color of the image. In contrast, a physical change involves a change in appearance, state, or form without altering the chemical composition of the substance, which is not the case with fading photographs.

Cutting anything is a physical change.

no, its physical change :)
Sharpening a pencil is a physical change, because there is no change to the chemical makeup of the pencil when sharpening it. It is simply chunks of wood being sliced off to reveal more of the lead.It is a physical change.
