What is meant by physical form?

This textbook provides a specific definition of chemistry: the study of the materials of which the universe is made and the transformations that these materials undergo. Obviously, such a general definition has to be very broad and nonspecific. From your point of view at this time, how would you define chemistry? In your mind, what are “chemicals”? What do “chemists” do?
