Its down to the molecules in the substance, in gases they are not that close to each other so they can move around quicker and faster so hence diffuse quicker in solids or most they are that tight they can not move are as easily.
expand
Yes, solids, liquids, and gases have different masses because their particles are packed differently. In general, solids have the most mass because their particles are closely packed, while gases have the least mass because their particles are spread out. Liquids have a mass between that of solids and gases.
Gases expand most on heating because their particles have high kinetic energy, causing them to move further apart. Solids expand least because their particles are tightly packed and have less freedom to move, limiting the expansion.
I think because mostly it is solids that are all around you, and what you notice the most. So you don't really pay attension to liquids or gases unless your handling them.
actually solids will be the best answer for this
The density of solids is generally higher compared to liquids and gases because the particles in solids are more closely packed together. Liquids have a higher density than gases due to their closer particle arrangement, but lower density than solids. Gases have the lowest density as their particles are the most spread out and have the most kinetic energy.
Sound travels fastest through solids because the particles in a solid are closely packed together, allowing vibrations to travel quickly. Liquids and gases have particles that are more spread out, which slows down the speed of sound.
Most nonmetals are gases at room temperature, such as oxygen, nitrogen, and fluorine. Some nonmetals, like sulfur and carbon, are solids at room temperature.
A sound wave can travel mor quickly in water than in air
Gases most easily form a solution, as they have higher molecular movement and can mix more readily with other substances. Solids and liquids typically require more energy input to form a homogeneous solution.
Gas expands the most for an increase in temperature, followed by liquids, with solids expanding the least. This is because the particles in gases have the most kinetic energy and move more freely than particles in liquids and solids, allowing them to expand more readily.
Sound travels the fastest in solids. Solids being the most denser make sound travel fastest as compared to liquids and gases which have speed of sound relatively less than solids.
