This would prevent different parts of the plant from getting too hot. Since, the initial pressure of the gas in cylinder P is 1 atm. Now, as soon as the stop cock is opened the gas will start flowing from cylinder P to cylinder Q which is completely evacuated and thus the volume of the gas will be doubled because both the cylinders have equal capacity. below we have mentioned complete Class 11 Science Syllabus. Previous NCERT Solutions for Class 11 Physics Chapter 11 Thermal Properties of matter NCERT Book Class 11 Physics Chapter 12 Thermodynamics B is completely evacuated. The NCERT Class 11th Physics textbooks are well known for it’s updated and thoroughly revised syllabus. If you have any query regarding NCERT Solutions for Class 11 Physics Chapter 12 Thermodynamics, drop a comment below and we will get back to you at the earliest. (a) What is the final pressure of the gas in A and B ? Scroll down for Thermodynamics from NCERT Book Class 11 Physics Book & important study material. Edition : Corrected Reprint 2071. In the first case, the work done on the system when the gas is brought from state P to state Q is 23.2 J. CBSE Physics Chapter 12 Thermodynamics class 11 Notes Physics in PDF are available for free download in myCBSEguide mobile app. These solutions for Thermodynamics are extremely popular among Class 11 Science students for Physics Thermodynamics Solutions come handy for quickly completing your homework and preparing for exams. Thermodynamics is the hot topic for the experts who prepare question papers. Therefore, the pressure of gas should be increased by a factor of 6.964, if the gas is to be compressed to quarter of its original volume. Hc Verma II Solutions for Class 11 Science Physics Chapter 26 Laws Of Thermodynamics are provided here with simple step-by-step explanations. SHARES. Following are the statements of second law of thermodynamics: Heat supplied to the system = 110 J/sec     [1 Watt = 1 J/sec]. The bodies are then said to be the thermal equilibrium. The rate of flow of water = 3.0 litres/min. NCERT solutions for class 11 physics is perfect for you to develop more understanding of this subject. CBSE Class 11-science Videos. Previous NCERT Solutions for Class 11 Physics Chapter 11 Thermal Properties of matter The stopcock is suddenly opened. Class 11 Physics NCERT Chapter 12, Thermodynamics. Answer: Question 12. Thermodynamics in physics is a branch that deals with heat, work and temperature, and their relation to energy, radiation and physical properties of matter. (d) Do the intermediate states of the system (before settling to the final equilibrium state) lie of its P-V-T Surface? The net heat absorbed by the system when the gas changes its state from state P to state Q is: Since heat absorbed,ΔQ=ΔU+ΔW\Delta Q=\Delta U+\Delta WΔQ=ΔU+ΔW, Therefore, ΔW=ΔQ−ΔU\Delta W=\Delta Q-\Delta UΔW=ΔQ−ΔU At what rate is the internal energy increasing? This NCERT solution consists of answers to the questions provided in the textbook, important questions in previous year question papers and CBSE sample papers. This is possible because of the infinitesimal difference in temperature between the system and the reservoir. (i). Define temperature on the basis of zeroth law of thermodynamics. The syllabus covered by this board is also helpful in attending other competitive exams such as JEE and NEET. Finally, the heat flow ceases and both attain the same temperature. These ncert book chapter wise questions and answers are very helpful for CBSE exam. The entire system is thermally insulated. ), Universal gas Constant, R = 8.3 J mol – 1 K – 1, Mass of Nitrogen, m = 1.8 × 10 – 2 kg = 18 g, Now, the number of moles, n = mass  of  N2Molicular  mass  of  N2=mM=1828\frac{mass\;of\;N_{2}}{Molicular\;mass\;of\;N_{2}}=\frac{m}{M}=\frac{18 }{28}MolicularmassofN2​massofN2​​=Mm​=2818​, Now, for Nitrogen Molar specific heat at constant pressure CP = 72×R=72×8.3\frac{7}{2}\times R=\frac{7}{2}\times 8.327​×R=27​×8.3. Pradeep Solution for Class 11 Physics is provided here for students to prepare for final exams and score well in the examinations.Pradeep Solutions is prepared by subject experts for solving the questions related to Physics, Chemistry and Biology by giving proper understandable solutions. Class 11 Physics Notes Chapter 8 Thermodynamics. NCERT Books Class 11 Physics: The National Council of Educational Research and Training (NCERT) publishes Physics textbooks for Class 11. Answer: Question 12. (d) The climate of a harbour town is more temperate (neither too hot nor too cool) due to formation of sea breeze at day time and land breeze at night time as already explained in Chapter 11. NCERT Solutions for Class 11 Physics in PDF format are available to download updated for new academic session 2020-2021, solutions of Exercises, Additional Exercises, ... Thermodynamics: It is the theory of heat, temperature and conversion of heat into work and vice-versa. (c) Air pressure in a car tyre increases during driving. 9 A thermodynamic system is taken from an original state to an intermediate state by the linear process shown in Fig.Its volume is then reduced to the original value from E to F by an isobaric process. The NCERT Solutions for Class 11 Physics Chapter 12 is given here so that students can prepare effectively for their exam. Answer: (a) In thermal contact, heat flows from the body at higher temperature to the body at lower temperature till temperatures become equal. 100 Qs. Thermodynamics:-It is the branch of physics which deals with process involving heat, work and internal energy.Thermodynamics is concerned with macroscopic behavior rather than microscopic behavior of the system.
