Humid air is lighter and less dense than dry air. Steam is water as a gas. Gaseous water is less dense than dry air.
Ice has a higher density than steam. This is because ice molecules are packed closely together in a solid state, while steam molecules are spread out in a gaseous state. Steam is also less dense than liquid water, as the molecules in steam have more energy and move farther apart when transitioning from liquid to gas.
Steam is less dense than liquid water because steam is in the gaseous state, while water is in the liquid state. The molecules in steam are farther apart and have more kinetic energy compared to liquid water molecules, which results in steam having a lower mass per unit volume.
The particles them self, assuming that you are referring to the individual atoms/molecules that makes up a liquid, does not change in "density" when going from one state of matter to another (liquid -> steam). However, the density changes for a certain amount of the matter, for instance one liter. One liter of water weighs a lot more than one liter of water steam. This is because the density of liquid water is much higher than water steam. The density of liquid water is 1000g/liter while the density of steam is 0.8g/liter. In other words, liquid water is over 1200 times denser than water vapor!
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.
Air is more buoyant than water because it has a lower density. The density of an object determines its buoyancy - objects with lower density than the fluid they are in will float. Air is less dense than water, so objects are more likely to float in air than in water.
No, it depends on the volume of water that can dissolve the salt. If the volume of water is more then it dissolves more salt and the density will be more and if the volume of the water is less then it dissolves less salt and the density will be less.

-- If the object floats in water, then its density is less than the density of water. -- If the object sinks in water, then its density is more than the density of water. -- If the object floats in air, then its density is less than the density of air. -- If the object sinks in air, then its density is less than the density of air.
The particles (atoms or molecules) have more energy and move about more. They are thus more spaced out. Think of a pan of water. It occupies a small volume. Heat it up and the whole house can be full of steam/water vapor/gas. So the same mass has a lot more volume in a gas and as density is mass/volume the density is considerably lower.
The weight does not determine if an object will float in water. If an object has a DENSITY that is more than the density of water then it will sink, if it's density is less than the density of water it will float.
You can determine if a solid object is more or less dense than water by comparing their densities. If the density of the object is greater than the density of water (1 g/cm^3), then the object will sink in water. If the density of the object is less than the density of water, then it will float.

You can determine whether a solid substance is more or less dense than water by comparing their densities. If the density of the substance is greater than the density of water (1 g/cm^3), then the substance is more dense. If the density of the substance is less than the density of water, then the substance is less dense.
You can determine if a substance is more or less dense than water by comparing their densities. Water has a density of 1 g/cm3 at 4 degrees Celsius. If a substance has a density greater than 1 g/cm3, it is more dense than water. If it has a density less than 1 g/cm3, it is less dense than water.
It's because of the density of the object; for example wood floats in water because its density is less then the density of water, and metal sinks because its density is more then the density of the water.
For floating in water: density under 1 g/cm3 For sinking in water: density more than 1 g/cm3
