NCERT Solutions For Class 11 Physics Chapter 11: Thermal Properties of Matter

Content Curator

NCERT Solutions for Class 11 Physics Chapter 11 Thermal Properties of Matter are given in the article. The matter is the one due to which a matter exhibits heat conductivity or it is the property that decides the nature of the matter in the presence of heat. Thus, thermal properties are exhibited by objects when heat passes through them. Temperature is one of the physical properties of matter.

Class 11 Physics Chapter 11 Thermal Properties of Matter belongs to Unit 7 Properties of Bulk Matter which along with Unit 8 and Unit 9 has a weightage of 20 marks. NCERT Solutions for Chapter 11 Class 11 Physics covers concepts of specific heat capacity, Latent heat formula, and Blackbody Radiation.

Class 11 Physics Chapter 11 – Concepts Covered

The thermal energy of a body is the quantity of heat that is required to raise the temperature of the whole body by a unit degree. If Q is the amount of heat that’s needed to produce a temperature change (Δt), then the thermal capacity of the substance is given as:

\(S = {Q \over \bigtriangleup t}\)

The Specific Heat Capacity of a substance is the amount of heat that is required to raise the temperature of a unit mass of a substance by 1° C.

\(S = {1 \over m} {Q \over \bigtriangleup t}\)

Calorimetry is concerned with the measurement of heat.

From the law of energy conservation: Heat gained by one body = heat lost by the other

The Basic Heat Formula: The heat Q that is required to raise the temperature of a substance with mass m of specific heat capacity s through t degrees is given by

Q = m x S x t

Newton’s law of cooling states that the rate of loss of heat in a body is proportional to the difference in temperature of the body and its surroundings provided that the difference in temperature is small and is not more than 40° C.

\({dT \over dt} = -K(T-T_s)\)

The negative sign implies that as time passes, the temperature decreases.
