Yes a feather is lighter than water. Water can be gallons. A feather however is no pounds. If you have a scale at home than fill up a cup of water than get a feather, from like a scarf a pillow etc. And put the water on first, then write down the number. Then put the feather on the scale and write down that number then compare.

Water vapor is a gas so it is in the air. Nitrogen and nitrogen are in the air too, but there is more nitrogen than anything in the air. I believe it rises because it is lighter, like a balloon filled with helium.
Hydrogen is lighter than Helium.
Continental crust is generally lighter than oceanic crust.
Ice is less dense than water. Less dense floats, more dense sinks. When water freezes, its volume expands (more space between molecules), which means its density decreases so it floats.* * Among compounds, this property is unique. Among elements, it is less rare. It is shared by: Si, Ga, Ge, Bi, and Sb.
in order for granite to float on water, it has to be lighter than water. because if its heavier than water, it will not float!
