Humidity is water vapor, not liquid water, and water vapor molecules are lighter than the molecules of nitrogen and oxygen that make up approximately 99% of the atmosphere. So, dry air is heavier than humid air.

Free expansion means the expansion of a gas when the external pressure (pext) ) is zero. So the expansion of a gas in vacuum is free expansion as the external pressure is zero. The work done in the free expansion of a gas is always zero, wether the process is carried out reversibly or irreversibly. Secondly, the free expansion of the gas isothermal if no heat exchange is allowed between  the system and the surrounding that is if the free expansion is carried out adiabatically, then it is isothermal.

OK here ur answer :- we know that air above to the lake or water surface is much cooler than that of ground air... So cool air freezes the top of water surface.. Most Lake doesn't freezes right from the bottom except around the edge bcoz ground 'insulates' the lake water.. That's why fish doesn't die even when water get cooled at bottom........... Hope it helps...... ???

First write the given compound in complete structure form and count the pi bond and sigma bond.whereas,single bond(C-C) have only sigma bond or let it be (C-H)also have only one sigma bond. Now the double bond case (C=C,C=H),there is one pi bond and one sigma bond....koi bhi case kyo na ho agar double bond hota hai to waha par ek pi bond aour ek sigma bond hota hai...Aabb third one(C=_C,C=_H) yani ki agar triple bond ho to waha par 2pi bond and 1sigma bond hota hai ,koi bhi case ho agar koi do atoms ke bich me triple bond ho to 2pi and 1sigma bond hota hai kyonki upar aour niche wala bond pi bond hota hai and the middle wala bond sigma bond hota hai......
