Kinetic theory of gases is based on the following basic assumptions
Let us suppose that a gas is enclosed in a cubical box having length
IMPORTANT POINTS
MAXWELL'S DISTRIBUTION LAW
Total number of independent co-ordinates which must be known to completely specify the position and
configuration of dynamical system is known as "degree of freedom f". Maximum possible translational
A graph representing the variation of pressure or variation of temperature or variation of volume with each
other is called indicator diagram
Thermodynamics is mainly the study of exchange of heat energy between bodies and conversion of the
same into mechanical energy and vice-versa.
DIFFERENT TYPES OF PROCESSES :
Isothermal Process
Iso- choric Process (Isometric Process)
Pressure remains constant in isobaric process
In the cyclic process initial and final states are same therefore initial state = final state
Work done = Area enclosed under P-V diagram
Isobaric Process : Pressure remains constant in isobaric process
The first law of thermodynamics is the law of conservation of energy. It states
that if a system absorbs heat dQ and as a result the internal energy of the system
Efficiency of a cycle
The specific heat capacity of a substance is defined as the heat supplied per unit mass of the substance
per unit rise in the temperature.
At room temperature average molar specific heat of all metals are same and is nearly equal to 3R
