Heat, Energy Conservation, and Thermodynamics: From Work to Internal Energy
This PowerPoint covers the concepts of heat, energy conservation, and the laws of thermodynamics. It begins with heat flow, explaining that heat is the transfer of energy from a hot object to a cooler one, refuting the caloric fluid theory and introducing energy transfer instead. The presentation discusses the units for heat, such as the joule and calorie, and the mechanical equivalent of heat discovered by James Joule. It explains the specific heat of materials, latent heat during phase changes, and the First Law of Thermodynamics, which emphasizes energy conservation. The presentation also covers the concept of work done by gases during expansion and compression, with applications in the ideal gas law and thermodynamic processes.
