PHYS 10 - Lecture 16 - Thermal Physics I: Temperature, Heat, and Ideal Gas

────────── Lecture 16 of 30-ish in "Physics 10 in 30 Lectures" 0:00:00 - Lecture 16 Intro 0:02:21 - Chapter 8 Overview, Part 1 0:25:29 - Heat Intro (Temperature and Forms of Energy) 0:40:08 - States of Matter, a Microscopic View 0:51:17 - Ideal Gas Law (Kinetic Theory of Gas) 1:06:36 - Boiling is a Cooling Process 1:16:59 - Calculations with Ideal Gas Law, Heat Capacity, and Latent Heat ────────── In *Lecture 16**, we start our first pass through **thermal physics* by separating a few ideas that students often mix together: *temperature**, **heat**, and **energy**. We’ll connect temperature to the *average microscopic motion of particles, and we’ll treat heat as *energy transfer* (not “something stored in an object”). Along the way, we build intuition for what’s happening at the particle level when materials warm up, cool down, or change phase. From there, we zoom in on a *microscopic model* of matter (solids, liquids, gases) and use that model to motivate the *ideal gas law* and the basic *kinetic theory* picture of gases. We finish by applying the ideas to real situations—especially the surprisingly useful idea that **boiling can be a cooling process**—and we work through example calculations using **PV = NkT**, **heat capacity**, and **latent heat**. Topics in this lecture: • Temperature vs. *heat* (and what each one actually means) • Forms of energy and *thermal energy* • States of matter from a *microscopic* point of view • *Ideal gas law* (PV = NkT) and *kinetic theory* intuition • Why *boiling* can cool an object (energy transfer + phase change) • Calculations with *PV = NkT**, **heat capacity**, and **latent heat* Textbook (free, online on LibreTexts): https://coaphys.xyz/phys10book Recommended reading: *Chapter 8 — Thermal Physics I (Temperature, Heat, and Ideal Gas)*
