In this chapter, you will study the physical properties of solids like elasticity, plasticity, and many other things. This chapter goes in depth to reach fundamental concepts like tensile stress, compressive stress, tangential stress, tensile stress, volume strain, etc. This chapter helps in building the foundation of various properties in solids.

This chapter will introduce you to some physical properties like gases and liquids. What common characteristics are between gases and liquids? How does fluid differ from solids? The difference in solids with liquids and gases are some questions that will be answered using this chapter. External forces like pressure and tension and its effects on fluids using mathematical expressions are some of the topics you will understand in this chapter.

This chapter will teach you the exact meaning of heat and how this heat is measured. There are various topics related to heat flow that will be discussed in this chapter. Some of the interesting daily life phenomena like why the wind reverses its direction near a sea beach or why the blacksmiths healthier iron rings before they fit a rim on the wooden wheel will be explained through this chapter. You will also learn why the temperature does not change when the water boils even though it goes through a great of heat change in the process in this chapter.

Thermodynamics usually deals with the ideas related to the temperature and heat as well as interconversion of heat and other forms of energy. This is considered as a macroscopic science. Furthermore, it deals with the bulk systems and often it does not include the molecular constitution of the matters.

This chapter will help you in understanding the favor of gases along with fast-moving molecules and atoms. Since the 19th century, Kinetic energy is being studied by some of the great scientists like Maxwell, Newton, Boyle, and many more. This and all is explained in this chapter of kinetic theory.

This chapter further dwells into projectile motion, rectilinear motion, and other similar motions that you have studied in earlier chapters. The study of oscillations is considered as very basic in physics. This chapter does into detail about the oscillation as well as oscillatory motion.

There different waves and its influences which will be understood through this chapter. Furthermore, this chapter will help you develop a conceptual study about the longitudinal and transverse waves, angular wave and wavelength number, frequency, and angular frequency, etc.

Physics is often one of the most dreaded subjects by students. However, if approached correctly it can soon turn to be of the easiest and most enjoyable subject. Not only can you score well in Physics but it can awaken a lifelong love for the sciences. So it is very important that the student take the correct approach while studying a conceptual subject like physics. Here we have the NCERT Solutions for Class 11 Physics to help you with this process.

Every single function of our life is actually governed by some law or concept of physics. It is said that physics can actually explain everything from the beginning of the universe to life in the present. In class 11 students are introduced with some basic concepts and laws of physics. We will be covering important chapters such as units of measurements, motion in a plane and straight line, gravitational force, kinetic energy, etc.

Here students are introduced to the international system of units and its history. They will learn about concepts such as base units and derived units. There are also numerical problems regarding volume and surface area of objects.

This is the introduction of Kinetics. We will learn about rectilinear motion, reference points, path lengths, relative velocity, acceleration, and other such interesting concepts. There are also some basic mathematical problems for the students to practice.

Students will learn about the differences between scalar and vector quantities. The chapter covers topics such as equality, addition, and multiplication of vectors, angular frequency and velocity, displacement and more.

This chapter further explains the motion of an object and the effect external forces can have on it. We will learn about the direction and magnitude of the force and the effects of gravitation. There are numerical problems and graphical representation to calculate the time and speed of moving objects.

In this chapter, we learn the theoretical concept of rotational motion and also the mathematical method of its calculation. The NCERT solutions will make the concepts clear and deepen the students understanding of the chapter.

Here students will learn about certain common physical properties of solids such as density, elasticity, tensile strength, volume strain, etc. We will see the real-life applications of certain solids such as steel and copper.

In this chapter, we will learn the concept and definitions of heat and temperature. We will learn how different matter behaves differently when the heat is applied to it. There are some mathematical problems about the conversion of celsius and kelvin.

Students will study in detail about oscillations and oscillatory motion. They will need to learn about periodic motion and harmonic motion and problems regarding them as well as their graphical representation.

Along with the NCERT Solutions for Class 11 Physics, Toppr provides its students with hundreds of videos, thousands of practice questions and other such invaluable materials. This will help students clear their concepts, solve their doubts, practice numerical problems all from the comfort of their home. With the right tools at their disposal, students are ensured of a good result.

Answer: A metal expands on heating. If a hole is made in the metal plate, the hole will also expand due to the expansion of the material. It can be explained by considering the air in the region of the hole and that air will also expand on heating. Therefore, the diameter of the hole increases always.

Answer: A body absorbs and emits thermal radiations at all temperatures except absolute zero, hence option A is incorrect.

Thermal radiations like all forms of radiation are electromagnetic in nature. Hence option B is correct.

All electromagnetic radiations reflect off mirrors, hence option C is incorrect.

All the electromagnetic radiation like thermal radiations travel with the velocity of the speed of light. Hence option D is correct.
