Pressure The molecules of a gas are in random motion. The rapidly moving molecules continually impact on the surface of the container and its effect is to produce a force over the surface. The force normal to unit area of surface is called pressure acting on the surface. The normal force exerted by the atmosphere…
Types of relation Void relation:- Let A be a set. Then, Φ ⊆ A x A and so it is a relation on A. This relation is called the void or empty relation on set A. In other words, a relation R on a set A is called void or empty relation, if no element…
Introduction about thermodynamics Energy is the capacity to do work energy cannot be created or destroyed but only can be changed into other forms (principle of conservation of energy). Thermodynamics mainly deals with interaction between heat and work (mechanical energy) and change in the property is associated with these interactions. The interaction between heat and…
Ideal gases The term gas is applied to a particular phase of a pure substance which will fills the system boundary, and no change of phase takes place or is contemplated. They always exist in gaseous form. For this reason, they have been called permanent gases. Perfect…
State, path and process State A state is condition of system and is specified by its properties. At a given state all the properties of a system have definite values Path Change of state of a system is the consequence of any operation in which properties will change. The series of states through which system…
