NCERT Exercise 10.6 | Thermal Expansion of Steel | Class 11 Physics

Описание: QUESTION:
A steel tape 1 m long is correctly calibrated at 27.0 °C. The length of a steel rod measured by this tape is found to be 63.0 cm on a hot day when the temperature is 45.0 °C. What is the actual length of the steel rod on that day? What is the length of the same rod at 27.0 °C? (Coefficient of linear expansion of steel = 1.20 × 10⁻⁵ K⁻¹)

This session focuses on understanding the concept of linear expansion, applying the correct expansion formula, and solving the numerical step by step so that students can confidently attempt similar real-life application questions in exams.
