Thermometry And Thermal Expansion
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.
Chapter Analysis:
Only two questions have been asked from this chapter in the past 11 years, with the last question appearing in the 2016 paper. Hence, this chapter falls in the low-weighted category and we should not be expecting anything more than 1 question from this chapter in the coming papers.
The below given graph will illustrate the above-mentioned analysis:

Year | 2019 | 2018 | 2017 | 2016 | 2015 | 2014 | 2013 | 2012 | 2011 | 2010 | 2009 |
---|---|---|---|---|---|---|---|---|---|---|---|
Questions | 0 | 0 | 0 | 1 | 0 | 0 | 1 | 0 | 0 | 0 | 0 |
Tips and Tricks:
1. Be thorough with the NCERT portion. Here is the link to the NCERT PDF version of this chapter:
2. Make Mind Map of the entire chapter for easier revision.
3. Solve the past year paper sincerely and make them at your fingertips and get acquainted with the type of question that can be asked in the coming papers.
4. Practice a large number of questions from this topic and leave no stones unturned to make this chapter one of your strengths.
5. Online video lectures must be looked upon as they will provide interactive animations thereby making the subject matter easier to understand.
Calorimetry
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:

Year | 2019 | 2018 | 2017 | 2016 | 2015 | 2014 | 2013 | 2012 | 2011 | 2010 | 2009 |

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.
Thermodynamics
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:

Year | 2019 | 2018 | 2017 | 2016 | 2015 | 2014 | 2013 | 2012 | 2011 | 2010 | 2009 |
---|---|---|---|---|---|---|---|---|---|---|---|
Questions | 2 | 3 | 2 | 3 | 2 | 2 | 2 | 0 | 2 | 1 | 2 |

Kinetic Theory Of Gases
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:

Year | 2019 | 2018 | 2017 | 2016 | 2015 | 2014 | 2013 | 2012 | 2011 | 2010 | 2009 |

Heat trasnfer (Conduction And Radiation)
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.
The below given graph will illustrate the above-mentioned analysis:
