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

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. 📘 Chapter: 10 – Thermal Properties of Matter 📌 Exercise Question Explained: 10.6 🎓 Class: 11 Physics 📚 Boards Applicable: NCERT | GSEB | ICSE This video is useful for: ✔ Class 11 students revising thermal expansion ✔ Students confused about temperature correction in measurements ✔ School tests and board exam preparation ✔ NCERT-based Physics numerical practice 🕗 Physics videos uploaded regularly at 8:00 PM. 📍 Physics by Neha Ma’am 📩 Academic enquiries: physicselixirbyneha@gmail.com 🔔 Subscribe for daily Class 11 Physics problem-solving videos. #Class11Physics #NCERTPhysics #StudentLife #StudentsOfIndia #StudyLife #ExamTime #SchoolLife #PhysicsNumericals #LearningIsFun #EducationVibes #ViralEducation #StudyGrind #fun #studentslife #studentfunnyvideo
