There are several ways to detect chemical changes in a substance. 1. Change in color (usually) 2. Bubbles fizz from substance (gas is produced) 3. Change in temperature (surrounding temperature in air DOES NOT influence change in substance's temperature) 4.
Being ductile, malleable, freezing, melting are some examples of physical changes of a substance. Physical changes do not form a new substance while chemical changes do. Examples of chemical changes are a rusting nail and combustion.
In a physical change the nature of the substance has not changed, just the way it looks, feels or tastes. Examples of physical changes are: glass breaking, water changing into ice, whipping cream. In chemical change the nature or chemical composition of the substance is changed. Examples of chemical change are: iron changing to rust, burning leaves, food spoiling.
when a pure substance undergoes a chemical change it is no longer that same substance. A chemical change changes the identity of the substance. Hope i helped
physical changes can be not permanent like solid-liquid-vapour chemical changes are permanent if not reversible
Physical changes can be recognized by changes in the appearance, shape, or state of a substance without changing its chemical composition. Examples include melting, freezing, or dissolving. Chemical changes, on the other hand, involve the formation of new substances with different chemical properties. Signs of chemical changes include color changes, gas production, heat release or absorption, and formation of a precipitate.
Physical changes are changes in appearance, state, or form of matter without altering its chemical composition. Chemical changes involve the formation of new substances with different chemical properties. Examples of physical changes include melting ice or tearing paper, while examples of chemical changes include rusting of iron or burning wood.

Changes in the state of matter are physical because they involve a change in the physical properties of a substance, such as its shape, volume, or density, without altering its chemical composition. Examples include melting, freezing, evaporation, and condensation.
The chemical properties of an object show what a chemical change did to that substance.
No, it is a Physical Change. Physical Changes are concerned with energy and states of matter. A physical change does not produce a new substance. Changes in state or phase (condensation, melting, freezing, vaporization, sublimation) are physical changes. Other examples of physical changes include crushing a can, melting ice, and breaking a bottle. Chemical changes take place on the molecular level. A Chemical Change produces a new substance. Some examples of chemical changes include combustion (burning) and rusting of a metal.

Well, darling, a physical change involves a change in appearance, like cutting a piece of paper, while a chemical change involves a change in composition, like burning that paper to ash. So, in simpler terms, physical changes are like a makeover, just changing the looks, while chemical changes are like a complete transformation, changing what's on the inside. Just remember, physical changes are skin-deep, but chemical changes go straight to the core.
