The Laws of Thermodynamics play such a fundamental role in the behaviour of the universe. They are so fundamental to that they form part of the core studies of both scientists and engineers. The are surprisingly conceptually difficult as concepts such as Entropy and the so called ‘Zero Point’ energy play a part. A student with a solid grounding in the Laws of Thermodynamics is well placed for studies of chemistry, heat engines, cell formation etc.

Video # Video Tutori­al Title Remarks
1 The Mean­ing of Tem­per­at­ure and Heat Is tem­per­at­ure a fun­da­ment­al quant­ity? What’s the dif­fer­ence between temp and heat?
2 The First Law of Thermodynamics ΔU = Q + W
3 Ideal Gas Law PV = nRT
4 Ein­stein Solids 3 Using E.S.1 and E.S.2 to dis­cov­er the real mean­ing of heat
5 Mul­ti­pli­city of an Ideal Gas (mon­atom­ic) Bring­ing us closer to an expres­sion for and defin­i­tion of Entropy
6 Ein­stein Solids 4 The mul­ti­pli­city for a large Ein­stein Sol­id (requires Taylor Series and Stirling’s Approximation)
7 Ein­stein Solids 5 The sharp­ness of the mul­ti­pli­city func­tion. N.B., for Entropy
8 The sharp­ness of the mul­ti­pli­city func­tion. N.B., for Entropy
9 The Second Law of Thermodynamics Entropy = S = k.ln(w)
10 Entropy What is Entropy?
11 Third Law of Ther­mody­anam­ics 1/2 As the tem­per­at­ure approaches zero, so does Cv and the Entropy
12 Third Law of Ther­mo­dy­nam­ics 2/2 The net increase in Entropy is the driv­ing force of heat
