Objectives
TO UNDERSTAND THE MOST IMPORTANT PHYSICAL QUANTITIES THAT CHARACTERIZE THE BULK PROPERTIES OF (MACROSCOPIC) MATTER AND THE RELATIONSHIPS BETWEEN THESE QUANTITIES.
•TO UNDERSTAND THE LAWS OF THERMODYNAMICS AND HOW THEY REGULATE MACROSCOPIC PHYSICAL PROCESSES, WITH SPECIAL ATTENTION TO ENERGY, VOLUME, AND PARTICLE EXCHANGE BETWEEN SYSTEMS AND TO TRANSFORMATIONS OF ENERGY.
•TO DEVELOP TOOLS FOR CHARACTERIZING BULK MATTER AT THE MACROSCOPIC LEVEL.
•TO UNDERSTAND THE RELATIONSHIP BETWEEN THE MICROSCOPIC VIEW (STATISTICAL MECHANICS) AND THE MACROSCOPIC VIEW (THERMODYNAMICS) OF MATTER.
