# HC Verma Heat and Temperature Solutions (Chapter 23)

HC Verma Chapter 23 Solutions for Class 12 Physics Part-2.’Heat and Temperature’ will guide you for HC Verma Class 12 Physics Solutions exams as well as competitive exams. Heat can be described as the degree or level of hotness or coldness of a body or environment. It is the transmission of energy from a hotter system to a cooler system due to a difference in temperature between them. In addition to understanding the concepts of heat, you will also study thermal equilibrium, linear expansion, volume expansion, the pressure of a gas at constant temperature and Young’s modulus.

HC Verma Concepts of Physics Part 2 Heat and Temperature Solutions contains a total of 4 exercises with around 64 questions. On solving the exercises of the chapter, you will be able to find the relation between Celsius and Fahrenheit, Kelvin, ice point, triple point, coefficient of linear expansion, and change of moment of inertia with respect to temperature. All these topics are important for a solid foundation of competitive exams like JEE, NEET and also for Class 12 Physics Part 2 exams.

HC Verma Heat and Temperature Solutions of HC Verma Class 12 Chapter 23 has been prepared by our subject matter experts with utmost clarity. Our excerpts follow the latest Physics syllabus for Class 12. The explanations provided are easy to understand the meaning of the chapter. These HC Verma Solutions will guide you in your competitive exam preparation in the best possible way.

## Important Topics for HC Verma Concepts of Physics Part-2 Solutions Chapter 23: Heat and Temperature

Thermal Equilibrium

Thermal equilibrium is defined as if there is no net flow of thermal energy among the two physical systems when they are related by a path absorptive to heat. Thermal equilibrium follows the zeroth law of thermodynamics.

Ice Point

The ice point is defined as the temperature equivalent to 32°F (0°C), where ice and water are in equilibrium in a mixture at one atmosphere of pressure.

Steam Point

Steam point is defined as the temperature 100°C (212°F), where water vapour condenses at one atmosphere of pressure.

Constant Volume Gas Thermometer

A bulb filled with a definite measure of dilute gas attached to a mercury manometer is known as a constant-volume gas thermometer. A constant-volume gas thermometer works in the principle of the law of Gay-Lussac and used to measure variation in pressure.

The Relation between Heat and Temperature

Heat is defined as the overall energy of molecular motion in a substance. It depends on the speed of the particles, the size or mass of the particles, and the type of particles in an object. The SI unit of heat is the joule.

Temperature is defined as the amount of the average energy of molecular motion in a substance. It does not depend on the type or the size of the object. The SI unit of temperature is Kelvin (K).

The Coefficient of Linear Expansion

The coefficient of linear expansion is defined as the rate of the increase of area, volume, or length of a body per degree increase in temperature to its area, volume, or length, respectively, at some particular temperature, mainly 0° C keeping the pressure constant.
