Important Topics for NCERT Physics Exemplar Solutions Class 11 Chapter 11 – Thermal Properties of Matter
Temperature and Heat
Heat and temperature are interrelated but are different concepts. Heat is the total energy of molecular motion in an element while the temperature is the amount of the average energy of molecular motion in an element. Temperature does not be determined by the size or type of object.
Measurement of Temperature
Temperature is the amount of the average kinetic energy of the atoms or particles in the system. It can be measured with the help of a thermometer. Thermometers are standardized in different temperature scales that traditionally have used different reference points and thermometric elements for definition.
Thermal expansion is the inclination of matter to change its area, shape, and volume in response to a change in temperature. Temperature is a monotonic function of the average molecular kinetic energy of an element. When an element is heated, the kinetic energy of its molecules rises.
Specific Heat Capacity
Specific heat capacity is the measure of heat energy necessary to increase the temperature of an element per unit of mass. It is also an example of an extensive property since its value is proportionate to the size of the system being observed.
Newton’s Law of Cooling
Newton’s Law of Cooling describes that the rate of change of the temperature of an object is proportionate to the variance between its own temperature and the ambient temperature.
Change of State
Changes of state are referred to as the physical changes in matter. They are reversible changes that do not include changes in matter’s chemical properties. Common changes in the state consist of condensation, melting, freezing, deposition, sublimation, and vaporization.
Heat transfer illustrates the flow of heat due to temperature changes and the consequent temperature distribution and changes. The study of transport phenomena distresses the exchange of momentum, energy, and mass in the form of convection, conduction, and radiation.
