This because when we place zinc in copper sulphate solution then due to lower reduction potential and higher oxidation potential it consists the ability to loose electrons to copper as copper have more reduction potential (0.34) therefore it gains electrons from zinc. due to transfer of electrons the colour faints and after some days we will see that whole of the zinc gots oxidised and becomes zn2+.
Depends on the solute: alcohol in water is lighter, salt in water is heavier than water.
It depends on what temperature it is at, and how well sealed the container. The higher the temperature, and the more the container is open to outside air, the fast it will evaporate. Exactly how long it will take is very difficult to determine however!
yes. Because methane is lighter than any liquid, bubbles of methane will always rise in solution.
It changes from dark red when added to a solution to a lighter reddish-orange colour if testing positive for lipids.
Galileo developed an experimental apparatus called the "weighing astration" to estimate the weight of air. In this device, he balanced a sealed container filled with air against an equal weight of water. He observed that the container became lighter when air was removed, leading him to conclude that air has weight.

It's because it's only gas (fuel) in a plastic container.

No, helium has weight, but it rises when its in an expandable container such as a balloon because it is lighter than the nitrogen rich atmosphere but inside of a rigid container the helium can only add weight. (see the mythbuster's episode about the helium football)
Yes.
Neither. It doesn't absorb water.

If the receptacle is still getting power, go to an auto parts store and buy a new lighter.
Dry pounds of what? Bread crumbs would be much lighter than flour.

check socket for power, if power perhaps lighter element is burned out, if no power check fuse check to see if power getting to lighter receptacle if so, replace receptacle
