### CBSE Class 11 Physics Chapter 11 – Thermal Properties of Matter NCERT Solutions

Matter refers to those object that occupies space and has a mass. Thermal properties of matter define the state of matter based on their temperature. Apart from this, there are other thermal properties of matter. In our NCERT Solutions for Class 11 Physics Chapter 11, we have described every topic of the chapter in easy language. Moreover, these solutions are explained so well that you will easily grasp the concept.

### Subtopics covered under NCERT Solutions for Class 11 Physics Chapter

#### 11.1 Introduction

This topic describes how we recognize heat and temperature using our common sense. Moreover, the topic gives several examples that help you to learn about temperature.

#### 11.2 Temperature and Heat

Temperature refers to the degree of heat present in an object. While heat refers to the temperature of the object. In other words, heat refers to the transfer of energy between two or more objects by virtue of temperature.

#### 11.3 Measurement of Temperature

This topic talks about the devices and unit of measure of temperature. In addition, the topic gives a to measure temperature in physics.

#### 11.4 Ideal-Gas Equation and Absolute Temperature

This topic describes the ideal gas equation that can measure the use of gas. While Absolute Temperature refers to the measure of temperature from zero to Kelvins, Celsius, or Fahrenheit. The equation for the ideal gas equation is

$$\frac{PV}{T}$$ = µR

#### 11.5 Thermal Expansion

It refers to the spread out of object’s due to change in its temperature. Also, the more heat you apply the bigger it will get.

#### 11.6 Specific Heat Capacity

This refers to the heat required to raise the temperature of a mass by a given amount of heat.

#### 11.7 Calorimetry

This refers to the change in the stat of a variable of the body for the resolve of driving the heat transfer related to the change in its state.

#### 11.8 Change of State

Generally, matter exists in three states gas, liquid and solid. This topic describes the change of states of an object due to the application of heat or temperature.

11.8.1 Latent Heat- It refers to the heat that is required to convert a solid into a liquid or a liquid into gas.

#### 11.9 Heat Transfer

It refers to the movement of heat from one object to another object of different temperature.

11.9.1 Conduction- It refers to the process by which heat transfer from one object to another object without the movement of an object.

11.9.2 Convection- It refers to the transfer of heat by the movement of the object. Also, it is possible only in liquids.

11.9.3 Radiation- It refers to that transfer of energy that does not need any carrier like the sun. Also, this energy is absorbed by every living and non-living thing.

11.9.4 Blackbody Radiation-It refers to that body that absorbs all incident electromagnetic radiation.

11.9.5 Greenhouse Effect- It refers to the increase in temperature of the surface of the earth due to greenhouse gases.

#### 11.10 Newton’s Law of Cooling

This topic explains Newton’s law of cooling with the help of an activity. Apart from that, the states that the change in temperature of an object is comparative to its own temperature and ambient temperature.
