Class 11

The NCERT Solutions for Class 11 Physics Chapter 10 Thermal Properties of Matter are outstanding study materials that will help you score good in the Class 11 Physics exam. These NCERT Solutions have answers to the questions given in your textbook.

We all already know about temperature and heat. The hotness of a body or object is called temperature. A kettle with boiling water is hotter than a box which has ice. In Physics, heat and temperature should be defined very carefully. This chapter 10 will help you learn about heat, its temperature and various processes of heat flow. NCERT Solutions for Class 11 Physics ateSaral are according to the latest Syllabus 2023-24 and are available in PDF format, which can be accessed for free by the students.

## Subtopics of Chapter 11 Thermal Properties of Matter

The NCERT syllabus to strategise the examinations for its Classes 10 and 12. The Physics Thermal Properties of Matter NCERT Solutions for Class 11 are given so that you can understand the concepts and score well in your exam.

We all already know about heat and temperature. Temperature is a measure of the ‘hotness’ of a body or object. As we all know that measure of temperature is obtained by using a thermometer. Liquid-in-glass thermometers show different readings for temperatures other than the fixed points because of differing properties of expansion.

Following are the some key points of Thermal Properties of Matter are given below.

• Heat is another form of energy that flows between a body and its surrounding medium by virtue of the temperature difference between them. The degree of hotness of the body is quantitatively represented by the term temperature.

• A liquid in equilibrium with vapour has the same temperature and pressure throughout the system; the two phases in equilibrium differ in their molar volume (i.e., density). This is correct for a system with any number of phases in equilibrium.

• Convection involves the flow of matter within any fluid due to unequal temperatures of its parts. When a hot bar placed under a running tap loses heat by conduction between the surface of the bar and water and not by convection within the water.

• At eSaral, we provide perfect study material in the form of notes, NCERT Exemplar problems, question papers and textbooks for the sake of students. Students are advised to take maximum help from the study materials in order to master in passing their examinations and entrance examinations.

## NCERT Solutions Class 11 Physics Chapter 10 Thermal Properties of Matter - Topic-Wise Discussion

Thermal properties of Matter Class 11 NCERT has 11 topics, and together they offer a detailed knowledge of the Thermal Properties of Matter. Following are topic-wise summary to provide you with an outline of this chapter.

### 1. Introduction

The chapter starts with a general introduction and helps students to get an overview of what they will learn throughout this particular chapter.

### 2. Temperature and Heat

The next section of NCERT solutions for Class 11 Physics Chapter 10 talks about the definition of heat and temperature. In this, students will learn the units used to measure hot and cold.

### 3. Measurement of Temperature

In this section of Thermal Properties of Matter Class 11 NCERT solutions explains the process of measuring temperature and its instruments used for that. It also discusses in detail about the thermometer, and its many scales.

### 4. Ideal Gas Equation and Absolute Temperature

This section of Chapter 11, discusses various properties of a gas, and how thermometers that use gas can perform better than the liquid-filled ones. This topic also explains the variables that describe the behavior of a gas. The ideal gas equation, along with theories of many different scientists is also a part of the discussion in this chapter.

### 5. Thermal Expansion

Thermal expansion is one of the most important sections of ch 10 Physics Class 11; it talks how various elements expand under the influence of heat. A daily life example mentioned here is that hot water is poured over metal lids in case it gets tightened. The reason here is that this hot water expands the metal of pan and makes it easy to open.

### 6. Specific Heat Capacity

Every item or object has a particular boiling point, and they react differently when they absorb thermal energy. For example, a bowl of water under heat starts to pop bubbles, until it becomes turbulent when the water starts boiling. This concept of heat capacity is described here in-depth, and you can learn about its various aspects.

### 7. Calorimetry

Calorimetry means the measurement of heat, and this segment of Physics Class 11 Chapter 10 NCERT solutions discuss that concept in detail. With the help of real-life examples used here, you can quickly understand this topic.

### 8. Change of State

There are three states to every matter which is solid, liquid and gas. The transition of an element from one state to another is known as change of state, and heat plays a pivotal role here. In this section, you will also learn about the concept of triple point, latent heat and conduction.

### 9. Heat Transfer

The transfer of heat is a common occurrence, and this 9th topic of Chapter 10 explains this regular event further. The concepts of radiation, convection and others are a part of has been discussed here.

### 10. Newton’s Law of Cooling

Every item, when left without any external or outside influence, cools down gradually, and this chapter of thermal properties of matter Class 11 Solutions go on further to explain in detail.

## NCERT Chapter 11 Physics Class 11 Marks Weightage

The final physics examination will be a total of 100 marks. Out of these 100 marks, 30 marks will be assigned to the practical and the remaining 70 marks will be for the theoretical examination. You should solve all NCERT theory questions and numericals before taking the final examination. This will help you to score the highest marks in their respective classes.

Question 2 : What is Newton's law of cooling?

Answer: Newton's law of cooling states that the rate at which an object cools is proportional to the difference in temperature between the object and the object's surroundings. Simply put, a glass of hot water will cool down faster in a cold room than in a hot room.
