In this Class 10 Physics Lecture 4, learn about the Applications and Consequences of Thermal Expansion in Real Life from the chapter Thermal Transformations, based on the National Book Foundation syllabus.

Thermal expansion plays an important role in many everyday tools and engineering systems. This lecture by Sir Anjum Teaches explains with real-life examples and diagrams how thermal expansion is applied in thermometers, bridges, railways, power lines, and even in opening bottle caps!

What You'll Learn in This Lecture:

Thermometers (Mercury & Alcohol): How thermal expansion of liquids helps measure temperature.

Bimetallic Strips: Used in thermostats and switches due to different expansion rates of metals.

Expansion Joints: Prevent cracks in bridges, railways, and pipelines during temperature changes.

Bottle Cap Opening Trick: Metal cap expands in hot water, making it easy to open.

Power Lines Sag: Wires are hung with slack to prevent breakage in winter due to contraction.

Machinery Design: Importance of accounting for expansion in machines and instruments.

Ignoring Expansion: Leads to cracks, short circuits, and structural damage.

Eiffel Tower Example: Tower expands up to 15 cm in summer due to thermal expansion.
