Lecture
This lecture covers the thermal properties of materials, including how they respond to heat and cold, how they transmit and store heat energy, and the concept of heat capacity in relation to temperature. The instructor explains the influence of material structure on thermal energy storage, focusing on vibrational energy storage in atoms and the relationship between temperature and vibrational modes. The lecture also discusses the variation of heat capacity with temperature, reaching a maximum value before decreasing to zero as all vibrational degrees of freedom are activated. The instructor poses a question about the behavior of heat capacity at low temperatures, inviting students to explore the principles of thermodynamics further.
