When a system in equilibrium is subjected to a change in temperature, pressure or concentration, the equilibrium is displaced in a direction which tends to undo the effect of the change. This is called the?
Answer: Option 1 Le Chatelier's principle states that a system will react to a change (disturbing the equilibrium) in such a way that it minimizes the change.

Directions : In each of the following questions a statement is given, followed by two conclusions. Give answer : Statements : Wind is an inexhaustible source of energy and an aerogenerator can convert it into electricity. Though not much has been done in this field, the survey shows that there is vast potential for developing wind as alternative source of energy. Conclusions : I. Energy by wind is comparatively newly emerging field. II. The energy crisis can be dealt by exploring more in the field of aero-generation.?
Answer: Option 5 The phrase 'not much has been done in this field' indicates that wind energy is a comparatively newly emerging field. So, I follows. The expression 'there is...
