Understanding BTUs: How We Actually Measure Heat Energy

What exactly is a BTU, and why do we use it to measure heat instead of just using temperature? In this video, we break down the British Thermal Unit (BTU) with clear, easy-to-understand visual experiments. You'll learn exactly how much energy 1 BTU represents, the crucial difference between heat and temperature, and how fuel sources like coal release thermal energy. Perfect for students, engineering enthusiasts, or anyone curious about thermodynamics! 📌 Timestamps: 0:00 - Introduction to Heat Measurement 0:45 - What is a BTU?
