Because there are more space between gas particles compare to solid materials.
molecules move more in gasses gasses>liquids>solids
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.
Solids do conduct heat better than gases, although not necessarily better than liquids. Some solids are actually composite materials, because they can have a porous structure which contains gas within the solid, and this results in solids that do not conduct heat very well. But it is the gas component which has this insulating property.
Solids, liquids, and gases can be made to contract by reducing their temperature. Cooling these substances causes their particles to move more slowly, resulting in a decrease in volume. This decrease in volume leads to contraction of the material.
Solids - Fixed volume and shape. Particles in a solid have a rigid structure and vibrate. Liquids - Fixed volume but no fixed shape. Particles in a liquid can flow and have more energy than in solids. Gases - No fixed volume and no fixed shape. Gas particles move with a lot of energy and fill the space available to them.
Molecules - They are more tightly packed in solids than liquids and gases
Solids ---heat---> Liquids ---more heat---> gases
Gases have the highest kinetic energy, followed by liquids, and then solids. -apex
Humans are more use to engaging and thinking about solids than liquids or gases. They are easier to find because they are what we are looking for.
A blended mixture of two or more solids, liquids, and/or gases is called a heterogeneous mixture.
Solids are usually more dense because solids have a smaller volume than liquids or gases, so the same amount of mass is in a smaller volume, making the density greater.
Gases have the highest particle speed, followed by liquids, and then solids. Gases have particles that are widely spaced and move quickly, while liquids have particles that move more slowly due to stronger intermolecular forces, and solids have the slowest particles due to their fixed positions.

how am i suposed to know
The motion of particles in gasses, liquids, and solids are all different. Gas particles can move much more quickly than solids.
The common denominator in solids, liquids, and gases is that they are all forms of matter. They differ in their arrangement of particles and the extent to which those particles move. Solids have tightly packed particles with little movement, liquids have particles that are more spread out with some movement, and gases have particles that are very spread out and move freely.
In solids and liquids the molecules are already very close together so they can't be squeezed together much more than that. In a gas molecules are very spread out so they can be compressed .
