What is the outcome of observing a chemical property?

Nothing

A new substance is formed with different properties

NaCl

A rise in thermal conductivity

Answer explanation

Observing a chemical property often leads to a chemical reaction, resulting in a new substance with different properties. This distinguishes it from physical properties, where the substance remains the same.
