What is easier to observe about an object, it’s physical properties or it’s chemical properties. explain why

Physical properties include color, smell, texture etc which can be easily observed but chemical properties include mass, volume reactivity which can only be observed when any changes in the chemical identity of the substance takes place.

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
