====== Chapter 11: Heat and Thermodynamics ====== {{ :fsc-pctb-11:notes:fsc-pctb-11-notes-ch11.jpg?nolink&600|Chapter 11: Heat and Thermodynamics}} This is a eleventh chapter of the book Physics 11 published by Punjab Curriculum and Textbook Board, Lahore, Pakistan. After studying this chapter the students will be able to: * State the basic postulates of Kinetic theory of gases. * Explain how molecular movement causes the pressure exerted by a gas and derive the equation $P = 2/3 N_0 <\frac{1}{2} mv^2>$. where $N_o$ is the number of molecules per unit volume of the gas. * Deduce that the average translational kinetic energy of molecules is proportional to temperature of the gas. * Derive gas laws on the basis of Kinetic theory. * Describe that the internal energy of an ideal gas is due to kinetic energy of its molecules. * Understand and use the terms work and heat in thermodynamics. * Differentiate between isothermal and adiabatic processes. * Explain the molar specific heats of a gas. * Apply first law of thermodynamics to derive $C_p - C_v= R$. * Explain the second law of thermodynamics and its meaning in terms of entropy. * Understand the concept of reversible and irreversible processes. * Define the term heat engine. * Understand and describe Carnot theorem. * Describe the thermodynamic scale of temperature. * Describe the working of petrol and diesel engines. * Explain the term entropy. * Explain that change in entropy $\bigtriangleup S = \pm \frac {\bigtriangleup Q}{T}$ * Appreciate environmental crisis as an entropy crisis. | **Theory**: |{{ :fsc-pctb-11:notes:fsc-pctb-11-theory-ch11.pdf |Download PDF}} | | **Question**: |{{ :fsc-pctb-11:notes:fsc-pctb-11-questions-ch11.pdf |Download PDF}} | | **Numerical**: |{{ :fsc-pctb-11:notes:fsc-pctb-11-numericals-ch11.pdf |Download PDF}} | {{tag>FSc FSc_Part1 PCTB Notes}}
