Define equilibrium state.

In changing the state of a gas adiabatically from an equilibrium state A to another equilibrium state B, an amount of work equal to 22.3 Jis done on the system. If the gas is taken from state A to B via a process in which the net heat absorbed by the system is 9.35 cal, how much is the net work done by the system in the latter case ? (Take 1 cal = 4.19 J)

At equilibrium :

There exist an equilibrium between solid SrSO_(4) and Sr^(2+) and SO_(4)^(2-) ion in aqueous medium. The possible equilibrium states are shown in figure as thick line. Now, if equlibrium is disturbed by addition of (a) Sr(NO_(3))_(2) and (b) K_(2)SO_(4) and dotted line represent approch of system towards equilibrium. Match the column given below : (I) addition of Sr(NO_(3))_(2) (II) addition of K_(2)SO_(4)

Give the characteristics of equilibrium constant.

STATEMENT-1: The physical equilibrium is not static but dynamic in nature. STATEMENT-2: The pysical equilibrium is a state in which two opposing process are proceeding at the same rate.

Hardy Weinberg equilibrium is affected by

How does the process of natural selection affect Hardy-Weinberg equilibrium? List the other four factors that disturb the equilibrium.
