Physical Properties vs. Chemical Properties: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Updated on October 26, 2023
Physical properties describe matter's observable characteristics without changing its composition; chemical properties explain how matter reacts or changes into new substances.

Key Differences

Physical properties pertain to the attributes of matter that can be observed or measured without changing the substance's chemical identity. Chemical properties, however, relate to a substance's ability to undergo changes that transform it into a different substance.

Physical properties include characteristics such as melting point, density, and color. These are aspects that can be noted without any chemical reaction taking place. Chemical properties, in contrast, involve potential reactions a substance can have, such as flammability or the ability to rust.

By examining a substance's physical properties, one can gather information about its state, texture, or appearance without inducing any chemical change. Chemical properties offer insights into how a substance can change under specific conditions, leading to the creation of new substances.

A crucial distinction is that physical properties can be observed without altering the substance's molecular structure. On the other hand, determining chemical properties requires the substance to undergo a chemical reaction, changing its original structure and forming new compounds.
