FAQs on Introduction & Basic Concepts of Thermodynamics Video Lecture - Physical Chemistry

1. What is thermodynamics?
Ans. Thermodynamics is the branch of physics that deals with the study of energy and its transformations, particularly in relation to heat and work. It focuses on understanding the behavior of systems and the transfer of energy between them.
2. What are the basic concepts of thermodynamics?
Ans. The basic concepts of thermodynamics include the first law of thermodynamics, which states that energy is conserved and cannot be created or destroyed; the second law of thermodynamics, which deals with the direction of energy transfer and the concept of entropy; and the third law of thermodynamics, which relates to the behavior of systems at absolute zero temperature.
3. What is the first law of thermodynamics?
Ans. The first law of thermodynamics, also known as the law of energy conservation, states that energy cannot be created or destroyed in an isolated system. It can only be transformed from one form to another or transferred between different systems. This law is based on the principle of conservation of energy.
4. What is entropy in thermodynamics?
Ans. Entropy is a concept in thermodynamics that measures the degree of disorder or randomness in a system. It is often referred to as the "arrow of time" because it determines the direction of energy transfer, which is from a state of lower entropy to a state of higher entropy. Entropy is closely related to the second law of thermodynamics.
5. What is absolute zero in thermodynamics?
Ans. Absolute zero is the lowest possible temperature in the thermodynamic temperature scale, denoted as 0 Kelvin (K) or -273.15 degrees Celsius. At absolute zero, the particles of a system have minimal motion and their thermal energy is at its lowest possible state. It is a fundamental concept in thermodynamics, especially when studying the behavior of gases.
