 # HC Verma Solutions Vol 2 Chapter 4 Laws Of Thermodynamics

HC Verma Solutions Vol 2 Chapter 4 Laws of Thermodynamics given here will help students to go through all the exercises and improve their ability to tackle all the questions related to the chapter. This is an important unit from an examination point of view. The chapter also focuses on enabling students to learn about fundamental physical properties like entropy, temperature, and energy that are all defined by the laws of thermodynamics. These topics are mainly found under thermal equilibrium.

Having HC Verma Solutions Part 2 will come in handy as it will improve the students’ ability to solve complex questions based on the four laws of thermodynamics: The zeroth law, the First Law, the Second Law, and the Third Law. The solution also contains answers to all the exercises given in the chapter and will ultimately help students to study productively and prepare well for the exams.

## Laws of Thermodynamics Key Topics

The chapter covers some of the topics like;

• Laws of Thermodynamics
• Work Done by Gas
• Heat Engines
• Reversible and Irreversible Processes
• Carnot engine

The HC Verma solutions are available in a PDF format which students can download and use it to study offline.

The solutions are also listed below for reference.

## Important Questions In Chapter 4

1. We apply a certain force F on a block of mass M and is displaced for distance d in the direction of the force. Explain the amount of work done by the force on the block? Also, clarify whether the internal energy changes because of this work or not?

2. State the condition for the efficiency of a Carnot engine to be equal to 1?

3. What does the first law of thermodynamics signify?

(a) conservation of momentum (b) conservation of energy (c) conservation of heat (d) conservation of work

4. Suppose the internal energy of an ideal gas is decreased by the same amount as the work done by the system. What is the process involved?

(a) An adiabatic process (b) The process is isobaric (c) The process must be isothermal (d) There is a decrease in temperature

5. Usually, when a hot object cools down, the heat dissipates from it. In such a process, will the entropy of the object decrease? State whether this process violates the second law of thermodynamics or not?
