When a change in matter affects the basic nature of the substance, it is called a chemical change. During a chemical change, the molecular structure of the substance is altered, resulting in the formation of new substances with different properties. Examples include rusting of iron or burning of wood. In contrast, physical changes do not alter the fundamental composition of the substance.
A change in some properties of matter without forming a different kind of matter is called a physical change. This can involve changes in state, shape, size, or appearance of the substance, but the chemical composition remains the same.
When a change in matter alters the basic nature of a substance, it is called a chemical change. In a chemical change, the substances involved react to form new substances with different properties than the original ones.
Nope. That is a physical change. If I crush a cookie into powder, it is still cookie- no chemical change. The form and appearance have changed. But pour powdered cookie onto your tongue, and it is still cookie.
It is when a substance changes it's form of matter, such as ice ( a solid) melting into water ( a liquid).
The phase transition from a solid to a gas is called sublimation. The reverse phase transition from a gas to a solid is called deposition.
This is called a change in the physical state of the substance. For example formation of ice from water is a change in the physical state of water.
When a substance changes from one state of matter to another it is called changing its state. Temperature changes are usually the main cause of this change.
A change in matter that produces a new substance is called a chemical reaction. This involves the breaking and forming of chemical bonds between atoms to create different molecules with distinct properties.
The chemical composition of the substance does not change when it changes its state of matter. The arrangement of atoms and molecules may vary, but the elements present in the substance remain the same.

By heating or freezing.

A change in matter that changes its physical form is called a physical change. This type of change does not alter the chemical composition of the substance, but only its physical properties such as shape, size, or state (solid, liquid, gas).
A chemical change in matter produces a new substance. A physical change, on the other hand, only alters the state or phase of matter without producing a new substance.
This change in the state of matter (liquid to solid) is called freezing; it is a physical change, the chemical nature of the molecules is not changed.
