During winters, moisture condenses in the from of dew and can be seen on plant leaves and grass. The entropy of the system in such cases decreases as liquids process lesser disorder as compared to gases. With reference to the second law, which statement is correct. for the above process?

A

The randomness of the universe decreases

B

The randomness of the surroundings decreases

C

Increases in randomness of surrroundings equals ito the decreases in randomness of system

D

The increases in randomness of the surroundings is greater as compared to the decreases in randomness of the system.

Text Solution

Verified by Experts

The correct Answer is:
A
As dew formation is spontaneous process, therefore, entropy or randomness of the universe will increase. As randomness of the system has decreased but randomness of the surrounding will increase significantly so that change is positive.

During winters, moisture condness in the form of dew and can be seen on plant leaves and grass. The entropy of the system in such cases decreases as liquids posses lesser disorder compared to gases. With prefrence to the second law, which statement is correct, for the above proces?

If a system at equilibrium is subjected to a change of any one of the factors such as concentration , pressure or temperature, the system adjusts itself in such a way so as to minimise the effect of that change. Effect of change in concentration on equilibrium: As we add or remove reactant (or product) the ratio of equilibrium concentratio become 'Q' (reaction quotient) and depending upon. QltK : equilibrium will shift ihn forward direction QgtK equilibrium will shift in backward direction Effect of change in pressure : If a system in equilibrium consists of gases, then the concentrations of all the components can be altered by changing the pressure. When the pressure on the system is increased, then equilibrium will shift in the direction in which there is decrease in number of moles i.e., towards the direction in which there is decrease in volume. Effect of change in pressure on melting point : There are two rypes of solids : Solids whose volume decreases on melting, e.g., ice, diamond, carborundum, magnesium nitride and quartz. Solid (higher volume) hArr Liquid (higher volume) The process of melting is facillitated at high pressure, thus melting point is lowered. Solid whose volume increase on melting, e.g., Fe, Cu, Ag, Au, etc. Solid (lower volume) hArr Liquid (higher volume) In this case the process of melring becomes difficult at high pressure, thuse melting point becomes high. Solubility of substances : When solid substance are dissolved in water, either heat is evolved. for endothermic solubility process solubility increase with increase in temperature. For exothemic solubility decrease with increase in temperature. Solubility of gases in liquids : when a gas dissolves in liquid, there is decreases in voolume. Thus increase of pressure will faavour the dissolution of gas in liquid. Effect of temperature : For endotherimic reacrtion as temperature increases reaction shift in backward direction Fe(l)hArrFe(s) Above equilibrium is favaured at :

Consider the following statements relating to the Non-Alignment Movement: 1. The Non-Aligned Movement (NAM) was created and founded during the collapse of the colonial system and the independence struggles of the peoples of Africa, Asia, Latin America and other regions of the world and at the height of the Cold War. 2. The First Summit of the Movement of Non-Aligned Countries was convened by the leaders of India, Indonesia, Egypt, Syria and Yugoslavia at Belgrade on September 1-6, 1961. 3. During the early days of the Movement, its actions were a key factor in the decolonization process, which led later to the attainment of freedom by many countries and to the founding of several new sovereign States. 4. The fundamental principle of the movement is to maintain equal distance from both the super powers by joining the military alliances of both the blocs.
