# Class 11 Physics Thermal Expansion Notes | Complete Handwritten Notes

In the thermal expansion chapter of Class 11 Physics, we study the principles of thermal expansion, including the coefficient of linear expansion, superficial expansion, and volume expansion. We explore how materials expand or contract with temperature changes and examine their applications in various fields.

Thermal Expansion falls under Heat and Thermodynamics branch of physics and has total 5 chapters. Heat and Temperature, Thermal Expansion, Quantity of Heat, Rate of Heat Flow and Ideal Gas are the chapters falling under this branch.

Syllabus:
Linear expansion and its measurement, Cubical expansion, Superficial expansion and its relation with linear expansion, Liquid Expansion: Absolute and apparent, Dulong and Petit method of determining expansivity of liquid.

Learning Objectives
After studying this chapter, students should be able to:

• Explain some examples and applications of thermal expansion, and demonstrate it with simple experiments.
• Explain linear, superficial, cubical expansion and define their corresponding coefficients with physical meaning.
• Establish a relation between coefficients of thermal expansion.
• Describe Pullinger's method to determine coefficient of linear expansion.
• Explain force set up due to expansion and contraction.
• Explain differential expansion and its applications.
• Explain the variation of density with temperature.
• Explain real and apparent expansion of liquid appreciating the relation; γᵣ = γ₉ + γₐ
• Describe Dulong and Petit's experiment to determine absolute expansivity of liquid. Solve mathematical problems related to thermal expansion
