Both steam and liquid water are made of the same substance (H2O). However, in the gaseous form (steam), the molecules are moving more quickly, and they are spread apart much farther. As such, the number of molecules per given volume (the mass per volume) is lower for steam. Mass per volume is the same thing as density.
Humid air is lighter and less dense than dry air. Steam is water as a gas. Gaseous water is less dense than dry air.
Fish weigh less in water because of buoyancy, which is the upward force exerted by a fluid that counteracts the weight of the object immersed in it. The water exerts an upward force on the fish that partially cancels out the downward force of gravity, making the fish weigh less in water than in air.
Steam takes up more space than liquid water because the molecules of water in steam have higher energy and are further apart from each other compared to when they are in liquid form. This causes steam to have a larger volume and be less dense than liquid water.
Because sea water is more dense than regular water
No, body fat does not weigh more than water. Both body fat and water have different densities, with fat being less dense than water. This means that for the same volume, water would weigh more than fat.

no
No. Oil is less dense than water, so 1 liter of oil will weigh less than 1 liter of water.
They weigh less than the water they displace.

Steam is formed when water is heated to its boiling point and changes from a liquid to a gas. The steam rises above the hot water because it is less dense than air and is buoyant, creating a visible cloud of water vapor.
Steam rises because when water is heated to its boiling point, it turns into vapor or steam. This steam is less dense than the surrounding air, so it rises upwards.
No, gasoline weighs less than water.
