When cooled gases change to liquids (usually) and then solids Solids don't change to gases upon cooling
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.
True
most of the elements are solids at room temperature.
Solids do not mix well because there shape can not change. But a liquid and a gas can change their form. For example- you can't just change the shape of ice, but you can change the shape of water. Hope that helps
Solids, liquids and gases expand when heated, liquids and gases expand much more that solids. Gases can be compressed

Most materials expand when heated due to increased molecular motion, and contract when cooled due to decreased molecular motion. Examples include gases, liquids, and solids such as metals and plastics.
Most substances are either solids, liquids, or gases at room temperature, depending on their molecular structure and intermolecular forces. The state of a substance can change with temperature and pressure.
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.
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.
Metals, like most solids will contract when cooled. When cooled the atoms or molecules slow down, vibrating less often, causing a smaller average separation between them.
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.
Most nonmetals are gases at room temperature, such as oxygen, nitrogen, and fluorine. Some nonmetals, like sulfur and carbon, are solids at room temperature.
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.
