What are the Chemical or Physical Change

Chemical Change vs. Physical Change?

The difference in physical and chemical reactions is composition. This chemical reaction produces different compositions for the material involved but there can be different physical changes resulting in a different appearance and smell of materials without changing their composition. Physical phenomena can be regarded, however, when a certain degree of the action takes place on a subject. To create a response there requires changes within the material that cause them to occur. Also, we should start using physical reactions as physical changes.

What are the Chemical or Physical Change :

Physical change occurs when the cause of change is removed from a substance and the original substance is recovered. On the other hand, some changes are referred to as chemical changes because they only affect the composition of substances and do not result in the formation of new substances.

Physical Change :

These are changes in which a substance’s physical properties and state change but its chemical properties remain unchanged. Simultaneously, after removing the cause of change, the original substance is recovered, such as water (H2O) in its liquid state, which transforms into gaseous state vapor (H2O) when heated, and solid-state ice when cooled (H2O).

the ice (H2O)

to cool

to get warmed up

To warm up, use water (H2O).

condensation

(solid-state) (liquid state) Vapor (H2O) (gas state)

Other examples include the formation of iron magnets, the sublimation of Nausadar (NH4Cl), and the dissolution of sugar in water

Properties of Physical Change :

  • 1. Only the physical properties of matter change, such as state, color, and odor.
  • 2. The original substance is obtained after the cause of change is removed.
  • 3. This is a one-time change.
  • 4. There is no new material created.

Chemical Changes :

These are the changes that occur when the chemical properties and composition of a substance change, resulting in the formation of a new substance. When a chemical change occurs, removing the source of the change does not always mean obtaining the starting substance. Coal combustion, for example, produces carbon dioxide gas.

CO2 CO2 CO2 CO2 CO2 CO2 CO2 CO2 CO2 CO2 CO2 CO2 CO2 CO (solid) a source of oxygen (gas) CO2 is a greenhouse gas (gas)

The reaction of carbon and oxygen produces carbon dioxide (CO2), and coal cannot be recovered from CO2 in this reaction. Curdling of milk, spoilage of cooked vegetables, rusting of iron, and so on are all examples of this.

Properties of Chemical Change :

  • 1. The chemical properties and composition of the substance formed as a result of a chemical change are completely different from the original substance.
  • 2. In most cases, the starting material is not recoverable.
  • 3. This is a long-term change.
  • 4. New material is being developed.

The distinction between physical and chemical change is as follows:

Chemical Changes :

The chemical properties and composition of the substance formed by the chemical change are completely different from those of the original substance.
In most cases, the starting material is not recoverable.
This transformation is irreversible.
New material is created in this process.
Rusting of iron, for example.

Physical Change :

Only the physical properties of matter change, such as state, color, and odor.
The starting material is obtained once the cause of change has been removed.
This is a one-time change.
It does not generate any new material.
Ice Water Vapor is an example.
