Energy

The temperature may be defined as the particular property which determines whether a system is in thermal equilibrium or not with its neighbouring system when…

If two systems A and B are separately in thermal equilibrium with a third system C, then the three systems are in thermal equilibrium with…

Thermal equilibrium is the condition in which two substances in physical contact with each other exchange no heat energy. Let consider a system requiring a…

Law of equipartition of energy states that for a dynamical system in thermal equilibrium the total energy of the system is shared equally by all…

Postulates of Kinetic theory of gases (1) A gas consists of a very large number of molecules. Each one is a perfectly identical elastic sphere.…

According to caloric theory of heat, heat was regarded as an invisible and weightless fluid called “caloric”. The two bodies at different temperatures placed in…

Application of Bernoulli’s theorem (i) Lift of an aircraft wing A section of an aircraft wing and the flow lines are shown in Figure. The…

In 1738, Daniel Bernoulli proposed a theorem for the streamline flow of a liquid based on the law of conservation of energy. According to Bernoulli’s…
