Auntie CeCe's Engineering Science Course: Heat, Temperature & Expansion | Lesson 11

Lesson 11 of 12 in Auntie CeCe's Engineering Science Course, Part 2 (exam build-up). We learn the difference between heat and temperature, Celsius and kelvin, specific heat capacity with Q = mcΔT, latent heat and the heating curve, linear expansion with ΔL = αLΔT, expansion joints and bimetallic strips, and the three ways heat travels. In this lesson: Heat vs Temperature; Temperature Scales; Specific Heat Capacity; Water Is Special; Worked Example: Kettle; How Long to Boil?; Latent Heat; Expansion; Linear Expansion; Worked Example: Steel Rail; Expansion in Use; Three Ways Heat Travels; Auntie's Recap. Formulas: K = °C + 273 · Q = m c ΔT · Q = m L (latent heat) · ΔL = α L ΔT · water c = 4200 J/kg°C (exam value) There's a 3-question quiz at the end (pause and work it out), then the answers and the course path. This course is general education. Follow your own syllabus, your instructor, and local codes for any real design work. #EngineeringScience #AuntieCeCe #LearnEngineering
