66 practice questions · 22 Easy · 22 Medium · 22 Hard
Practise Class 11 Physics Chapter 11, "Thermal Properties of Matter", with 66 NCERT-aligned multiple-choice questions. The set is split into 22 Easy, 22 Medium and 22 Hard questions, so you can warm up on the fundamentals and then push into the exam-level problems that separate top scorers in CBSE Board exams, JEE Main, JEE Advanced and NEET UG.
"Thermal Properties of Matter" is one of the chapters where numerical problem-solving, derivations and conceptual application really pays off. Each MCQ on this chapter is timed and uses exam-grade marking (+2 correct, −1 wrong, 0 skipped), training the same accuracy-under-pressure that real papers demand. Every question carries a short explanation, so a wrong answer becomes a quick lesson rather than a dead end — the fastest way to close gaps before a test.
Use this chapter as targeted revision: attempt the Easy set first to confirm your basics on Thermal Properties of Matter, then move to Medium and Hard to test application and problem-solving. Your accuracy, streaks and XP save automatically, and the chapter feeds into your overall Class 11 Physics mastery score. A few sample questions are shown below; sign in free to practise all 66.
Key concepts: Thermal Properties of Matter (Class 11 Physics)
This chapter covers temperature and heat, thermal expansion, specific and latent heat, and the modes of heat transfer.
- Temperature & heat
- Temperature measures the degree of hotness; heat is the energy transferred due to a temperature difference.
- Thermal expansion
- Solids expand linearly (α), in area (β = 2α) and volume (γ = 3α) on heating.
- Specific & latent heat
- Q = mcΔT for temperature change; Q = mL for a change of state at constant temperature.
- Heat transfer
- Conduction (solids), convection (fluids) and radiation (no medium needed).
- Radiation laws
- Stefan–Boltzmann law (E ∝ T⁴), Newton's law of cooling, and Wien's displacement law.
Key formulas — Thermal Properties of Matter
💡 Exam tips for Thermal Properties of Matter
- During a change of state temperature stays constant; the heat goes into latent heat (Q = mL).
- Remember the expansion relations: β = 2α and γ = 3α for isotropic solids.
