Thermal Physics: Fluid Mechanics and Heat Transfer

This lecture covers the concepts of fluid mechanics, including fluid properties, hydrostatics, Archimedes' principle, Bernoulli's theorem, Poiseuille's law, turbulent flow, cohesive forces, surface tension, Laplace's law, and capillarity. It also discusses temperature, thermal expansion, specific heat, changes of state, conduction, convection, and radiation. The instructor explains the microscopic origin of heat, diffusion, and thermal expansion, providing examples and values for different materials. The lecture further explores the concepts of heat capacity, latent heat, and phase changes, emphasizing the importance of pressure in determining melting and boiling points.
