Similarities Between Physical and Chemical Changes  

, , Comments Off on Similarities Between Physical and Chemical Changes  

A physical change affects only the material’s physical attributes, including size, shape, and texture. It does not involve any change in the ingredient makeup.

In case of a chemical change, the chemical constituents of a substance undergo modification in the ingredients making the matter into being. The new substance has different chemical components than the old one. 

In this article, you can learn about the fundamental similarities and differences between physical and chemical changes.

Similarities between physical and chemical changes:

The most common similarity in both physical and chemical changes is that they cause a difference in the state of the original matter. 

Also, energy transitions are constantly present alongside chemical and physical changes. For example, both reactions can emit and absorb energy in the case of heat. Both types of reactions generate novel molecules. Those are the only three spots where the two reactions appear to overlap; other than that; they are pretty distinct. 

Differences between physical and chemical changes include: 

  • In a physical change, the change occurs in the appearance and form of matter, such as liquid, solid, or gas.
  • Changes in basicity, acidity, and other chemical properties occur during a chemical change. It involves breaking molecular or atomic bonds into a new modified existence.


How can you tell the difference between physical and chemical changes?  

When something undergoes a physical change, its outside appearance alters, but its underlying composition remains unchanged. On the other hand, a chemical change invariably results in the emergence of at least one new material with novel characteristics. 

Why is it important to know the difference between physical and chemical changes?  

Understanding the distinction between chemical and physical transformations is crucial. Although many of the shifts are simple, there are still some rudimentary ideas to keep in mind. Alterations in a thing’s physical form are commonly meant by the term “physical change.” Chemical changes occur at the molecular level when two or more molecules interact.

What are the 5 chemical and physical changes?  

  • Changes in color, precipitate formation, gas production, odor, and temperature are the five conditions of chemical change. 
  • Numerous procedures can bring about physical transformations, including slicing, bending, dissolving, freezing, boiling, and melting. 

What are some examples of physical changes?  

  • Salt dissolution in water 
  • Freezing of water to produce ice 
  • Candle wax dripping 
  • Water vaporization 
  • Heating nails 
  • Sugar dissolution in water.

What are examples of chemical changes? 

  • To heat with wood 
  • A corroding iron 
  • While chewing on a slice of bread 
  • Substituting Sodium in a Reaction for Water 
  • Methods for decomposing food.
