What is thermodynamics?
Thermodynamics is one of the types of physics which is the combination of two words ” thermal + heat”, thermal means heat and dynamic mean motion. So literally thermodynamic mean study of the motion of heat. There are three laws of thermodynamics which are:
Thermodynamic plays a vital role in our lives.
- We were not able to get the energy to move. We get energy from food as a result of the metabolism process which is the example or application of the first law of TD.
- Refrigerators, air conditioners, cars, airplanes, buses, ships all needed a thermodynamic system to work.
- Heat pumps and heating systems are due to TD.
- Electricity is now being produced by using a thermodynamic cycle or process.
It is applicable only in the macroscopic world and not in microscopic.
- State the Basic Postulates of the kinetic theory of gasses
- Derive gas laws on the basis of kinetic theory
- Internal Energy of an ideal Gas
- To understand the term work and heat in thermodynamics
- Differentiate between isothermal and adiabatic processes
- Explain the molar specific heat of a gas
- Apply first law of thermodynamics to derive Cp – Cv = R
- Explain second law of thermodynamics and its meaning in terms of entropy
- Understand the concept of reversible and irreversible processes
- Define the term heat engine
- Understand and describe Carnot Theorem
- Describe temperature scales
- Describe the working of petrol and diesel engine
- Explain the term entropy
- Appreciate the environment crisis as an entropy crisis.
