All Thermal Properties of Matter Formulas at a Glance
Every formula sits in one table below, with its meaning and SI unit. Learn the expansion and calorimetry rows first, since most numericals use them.
| Formula | What it means | SI unit |
|---|---|---|
| ΔL = αL0ΔT | Linear expansion of a rod on heating | metre (m) |
| ΔA = βA0ΔT, β = 2α | Area expansion; area coefficient is twice linear | m2 |
| ΔV = γV0ΔT, γ = 3α | Volume expansion; volume coefficient is thrice linear | m3 |
| Q = mcΔT | Heat to change a body's temperature | joule (J) |
| Q = mL | Latent heat during a change of state | joule (J) |
| C = Q/ΔT | Heat capacity of a body | J K-1 |
| H = Q/t = kA(T1−T2)/L | Rate of heat conduction through a slab | watt (W) |
| dT/dt ∝ (T−Ts) | Newton's law of cooling | K s-1 |
| E = σT4 | Stefan-Boltzmann law for a black body | W m-2 |
| λmT = b | Wien's displacement law | metre (m) |
The three expansion coefficients follow α : β : γ = 1 : 2 : 3 for an isotropic solid.
Temperature Scales and Calorimetry for Thermal Properties of Matter
Convert scales and apply the principle of calorimetry before any heat numerical. Heat lost equals heat gained when no heat escapes.
- Scale conversion: (C−0)/100 = (F−32)/180 = (K−273.15)/100.
- Principle of calorimetry: heat gained by cold bodies = heat lost by hot bodies, using Q = mcΔT.
- Change of state: during melting or boiling, temperature stays constant and Q = mL supplies the latent heat.
Key Constants and Definitions for Thermal Properties of Matter
Boards and entrance papers often ask for a constant or a defined value. The list below has the values students must recall.
- Stefan-Boltzmann constant: σ = 5.67 × 10-8 W m-2 K-4.
- Wien's constant: b = 2.9 × 10-3 m K.
- Specific heat of water: 4186 J kg-1 K-1 (1 cal g-1 °C-1).
- Latent heat of fusion of ice = 3.33 × 105 J kg-1; latent heat of vaporisation of water = 22.6 × 105 J kg-1.
- Triple point of water = 273.16 K.
How to Revise Thermal Properties of Matter Formulas Before the Exam
Use this class 11 physics formula sheet chapter 10 thermal properties of matter for a fast recap the night before a test, in about 20 minutes.

FAQs on Thermal Properties of Matter Class 11 Physics Formula Sheet
Thermal Properties of Matter Formula Sheet - Frequently Asked Questions
Ques. What formulas does the class 11 physics formula sheet chapter 10 thermal properties of matter cover?
Ans. This class 11 physics formula sheet chapter 10 thermal properties of matter covers linear, area and volume expansion, the calorimetry relation Q = mcΔT, latent heat, the conduction rate, Newton's law of cooling, the Stefan-Boltzmann law and Wien's displacement law.
Ques. How are the expansion coefficients α, β and γ related?
Ans. The area expansion coefficient is twice the linear one, β = 2α, and the volume expansion coefficient is thrice the linear one, γ = 3α. So the three coefficients are in the ratio 1 : 2 : 3.
Ques. What is the Stefan-Boltzmann law?
Ans. The Stefan-Boltzmann law states E = σT4, where σ = 5.67 × 10-8 W m-2 K-4 and T is the absolute temperature in kelvin.
Ques. What does Newton's law of cooling state?
Ans. Newton's law of cooling gives dT/dt ∝ (T−Ts), valid for a small temperature difference. A hot body cools faster when the gap between its temperature and the surroundings is large.
