It's called a physical change.
A change that only affects the physical properties of a substance is known as a physical change. This type of change alters characteristics such as shape, size, and state of matter without affecting the chemical composition of the substance. Examples include melting, freezing, and dissolving. In a physical change, the substance remains the same at the molecular level.
A physical change does not involve a change in the chemical composition or nature of the substance. It only affects the physical properties, such as shape, size, or state of matter.
Chemical changes change to a substance`s chemical formula but a Physical change only affects attributes like color shape or size
Because melting only affects the state of matter that the melted substance is, it doesn't change the chemical properties.
Because melting only affects the state of matter that the melted substance is, it doesn't change the chemical properties.
A physical change does not alter a substance's chemical composition; it only affects its physical properties like shape, size, or state of matter. Examples include melting, freezing, or boiling.
physical changes
Heating potassium chloride crystals is a physical change because it only affects the physical state of the substance (solid to liquid) without changing its chemical composition.
a physical change will only alter the appearance but will NOT change the substance to another substance =)
Physical. A phisical chage only affects the sapearance. A chemical change affects the make-up of the substance. If you cut glass than you are just chugging the shape of the glass, but it is still glass.
Pungent odor is a physical change because it only affects the sense of smell without altering the chemical composition of the substance emitting the odor.
