1 The classical thermodynamics can be understood as (select only one)

	a) An elaborate study of thermodynamics that is based on the behavior of individual particles of the substance
	b) A macroscopic approach to the study of thermodynamics that does not require the knowledge of the behavior of individual particles of the substance
	c) A microscopic approach to the study of thermodynamics that is based on the average behavior of large groups of particles
	d) A macroscopic approach to the study of thermodynamics that is based on the behavior of small number of particles
	e) none of the above
