Humid air is lighter and less dense than dry air. Steam is water as a gas. Gaseous water is less dense than dry air.
To find the density of an irregular shape solid lighter than water, you can use the following steps: Weigh the solid in air to determine its mass (m). Weigh the solid while it is fully submerged in water to determine its apparent mass (m'). Calculate the density using the formula: Density = (m / (m - m')) * density of water.
Elements more massive than iron are created through processes such as supernova explosions and neutron star mergers, where extreme conditions allow for the fusion of lighter elements into heavier ones.
Fake gold chains often feel lighter than real gold chains because they are typically made of materials that are less dense than gold, such as brass or alloy metals. These materials are lighter in weight compared to solid gold, which is a dense metal. This difference in density is why a fake gold chain might feel lighter.
Temperature in this instance will not affect density, but rather pressure. The density of the gas will be much smaller than the density of a liquid or solid of the same chemical because it is a gas. The formula for density is mass over volume, and a gas has no measurable mass, making the gas always less dense than the liquid and the solid.
Gaseous water is lighter than air. Clouds are composed (mainly) of gaseous water.
Nitrogen, oxygen, and carbon. (NO, NO2, O2, O3, CO, CO2) These elements are in period 2 and tend to form gaseous oxides rather than the solid oxides of period 3. i.e SiO2, P4O10, SO3 (gaseous at STP).
Uranium is not lighter but heavier than many of the other elements; the density of uranium is 19,05 g/cm3 and the atomic weight is 238,02891.

Nuclear fusion only releases energy when elements lighter than iron are involved. This is because elements lighter than iron release energy due to the process of fusion, while elements heavier than iron require energy to be input for fusion to occur.
Not better, just a different application.
A compound is not lighter than an element, if that element is part of the compound. Some compounds, like H2O would be lighter than, say, the element lead, but it is not lighter than the elements that make it up, i.e. hydgrogen and/or oxygen.
Balloons! Gaseous Helium is easily compressed and is stable, (as opposed to Hydrogen). It is lighter than surrounding air.
Less expensive than solid wood, lighter weight to work with, lighter weight finished project, can be matched with other wood, easier to cut than some solid woods
Lighter elements are composed of fewer protons and neutrons compared to heavier elements. They tend to have fewer total nucleons and lower atomic numbers. Lighter elements are typically found at the beginning of the periodic table, while heavier elements are found towards the end.
Lighter elements tend to have neutrons equal to protonms or only a slight excess. Heavier elements have an excess of neutrons over protons
In fact there are seven elements lighter than oxygen: hydrogen, helium, lithium, beryllium, boron, carbon and nitrogen.
