FAQs on Chapter 5 Workbook: Thermodynamics - Topper Handwritten Notes & Videos for GATE ME - Mechanical Engineering

1. What is thermodynamics?
Ans. Thermodynamics is the branch of physics that deals with the relationships between heat, work, and energy. It focuses on the transfer of energy and its conversion from one form to another.
2. What are the laws of thermodynamics?
Ans. The laws of thermodynamics are fundamental principles that govern the behavior of energy and its transformations. The four laws are: 1) The first law, also known as the law of conservation of energy, states that energy cannot be created or destroyed, only transferred or converted. 2) The second law states that the entropy of an isolated system always increases or remains constant in any natural process. 3) The third law states that the entropy of a system approaches zero as the temperature approaches absolute zero. 4) The zeroth law establishes the concept of thermal equilibrium and the transitive property of temperature.
3. What is the difference between heat and temperature?
Ans. Heat and temperature are related but distinct concepts. Temperature measures the average kinetic energy of the particles in a substance, while heat is the transfer of energy between two objects due to a temperature difference. Temperature is measured in degrees Celsius or Fahrenheit, while heat is measured in joules or calories.
4. What is an example of a thermodynamic system?
Ans. A thermodynamic system is a region of space that is chosen for study. It can be as simple as a gas-filled container or as complex as an entire planet. An example of a thermodynamic system is a gas-filled balloon, where the gas inside is the system and the balloon itself is the surroundings.
5. How does thermodynamics relate to everyday life?
Ans. Thermodynamics has numerous applications in everyday life. It helps us understand and improve the efficiency of engines and power plants, as well as the behavior of refrigerators and air conditioners. It also plays a role in understanding weather patterns, the functioning of biological systems, and the behavior of materials.
