[Chemistry Tips] Physical vs chemical

Hi student,

Today, we will start another mini-series - common confusions in chemistry.

The first one that comes to mind is physical properties vis chemical properties.

When asked about chemical or physical properties of a species, you ought to know the difference (common exam questions).

Chemical properties: The properties enable one substance to be converted into another brand new one - they describe how a substance reacts with other substances. Water could turn into H2 and O2 - that is its chemical property since new species are formed.

Physical properties: The properties describing the physical characteristics of a substance. Typical properties are the mass, volume, density, color, and phase. Water can be vaporized into steam - that is its physical property since no new substance is formed; only the phase changes (liquid to gas phase).

So to tell the difference, just ask yourself a simple question: Is there a new substance formed?

Until next time, student, keep it up!
