NEET Thermal Physics Chapters 2022 2023 2024

Introduction:

Thermometry is the process of measuring temperature. Temperature is basically a measure of the amount of kinetic energy, particles possess. Nowadays, there are many different types of thermometers, for example glass in tube, thermistor, thermocouple, radiation thermometer etc.

Introduction:

Calorimetry is the science or act of measuring changes in state variables of a body for the purpose of deriving the heat transfer associated with changes of its state due, for example, to chemical reactions, physical changes, or phase transitions under specified constraints. Calorimetry is performed with a calorimeter.

Chapter Analysis:

At least one question has been asked from this chapter in the years between 2009-2019 with the exception of 2018 and 2011 where the question count fell to 0. In 2009, 2 questions were asked. 10 question have been asked collectively in the past 11 years, making it a low-weighted chapter and hence, we should not expect anything more than 1 question from this chapter.
The below given graph will illustrate the above-mentioned analysis:

Tips and Tricks:

1. NCERT must be read properly for this chapter as it covers most of the topics briefly. Here is the link to the NCERT PDF version of the chapter:
2. Practice a large number of questions from this topic and leave no stones unturned to make this chapter one of your strengths.
3. Online video lectures might help the student in having a clearer understanding of the topic.

Introduction:

Thermodynamics is the branch of Physics that deals with heat and temperature, and their relation to energy, work, radiation and properties of matter. The behavior of these quantities is governed by the four laws of thermodynamics which convey a quantitative description using measurable macroscopic physical quantities, but may be explained in terms of microscopic constituents by statistical mechanics. Thermodynamics applies to wide variety of topics in science and engineering, especially physical chemistry, chemical engineering and mechanical engineering, but also in field as complex as meteorology.

Chapter Analysis:

With 21 question in the past 11 years, this chapter happens to be a medium-weighted one. This chapter has not evaded the hands of the paper setters from 2013, with a total of 16 questions being asked between 2014-2019. This chapter falls in the category of medium-weighted chapter and hence, we should expect atleast 2-3 question from this chapter going by the general tred.
The below given graph will illustrate the above-mentioned analysis:

The important topics to be covered from this chapter are:
• Thermal Equilibrium and Definition of Temperature
• Heat, Work and Internal Energy
• First Law of Thermodynamics
• Isothermal and Adiabatic Processes
• Second Law of Thermodynamics
• Reversible and Irreversible Processes
• Heat Engine and Refrigerator
• Laws of Thermodynamics

Introduction:

Kinetic Theory of Gases describes a gas as a large number of submicroscopic particles, all of which are in constant, rapid, random motion. The randomness arises from the particles’ many collisions with each other and with the walls of the container. KTG explains the macroscopic properties of gases, such as pressure, temperature, viscosity, thermal, conductivity and volume, by considering their molecular composition and motion. The theory posits the gas pressure results from particles’ collisions with the walls of a container at different velocities.

Chapter Analysis:

Although no question was asked in the previous year, the period between 2013-2018 had question being asked with 2015 alone accounting for 2 questions. With a total of 8 questions being asked in the past 11 years, this chapter falls in the category of low-weighted chapter and hence, we should be expecting at max 1 question from this chapter.
The below given graph will illustrate the above-mentioned analysis:

The important topics to be covered from this chapter are:
• Equation of State of a perfect gas
• Work done in compressing a gas
• Kinetic Theory of Gases
• Concept of Pressure
• Kinetic Interpretation of Temperature
• RMS Speed of Gas Molecules
• Degrees of Freedom
• Law of Equi-partition of Energy
• Application to Specific Heat Capacities of Gases
• Concept of Mean Free Path
• Avogadro’s Number

Introduction:

Heat Transfer is a discipline of thermal engineering that concerns the generation, use, conversion and exchange of thermal energy between physical systems. Heat transfer is classified into various mechanisms, such as thermal conduction, convection and radiation, and transfer of energy by phase changes. Engineers also consider the transfer of mass of different chemical species, either cold or hot to achieve heat transfer. While these mechanisms have distinct characteristics, they often occur simultaneously in the same system.

Chapter Analysis:

The last time this chapter was skipped from the NEET question paper was way back in 2013. Last year, 2 questions were asked while the years between 2014-2018 had one question being asked each time. With a total of 10 question being asked in the past 11 years, this chapter falls in the low-weighted chapter category and hence, we should not expect anything more than 1-2 question in the upcoming papers.
