The expression of work done on a gas or by a gas is. Everything external to that system is called environment or surroundings. It is the energy which is transferred from a system to surrounding or vice-versa due to temperature difference between system and surroundings. Thermodynamics is a important and vast topic when it comes to NEET. heat given to the system is equal to work done (area of cycle). First law of thermodynamics gives a relationship between heat, work and internal energy. The efficiency of heat engine η is never greater than unity, η =1 only for ideal engine & for practical heat engine η < 1. The physics concepts and formulas of class 11 also you need to prepare for NEET along with the concepts and formulas for class 12. The effect of naturally occurring processes is always to increase the total entropy (or disorder) of the universe. The aim of this lecture is to provide a quick and crisp revision of one of the important topic of chemistry from competitive point of view i.e. Question: Find, for which of the given processes the would the entropy change be zero? In cyclic process, there is no change in internal energy (shown in fig.). Path along which state of a system changes. In given process dW = 0, dQ < 0 then for a gas. It is also macroscopic and path dependent function. The heat absorbed in process I is more than that in II.
