As the temperature of a substance increases, its particles move faster.
Gas particles are not close together; they are far apart and move freely in all directions. Gas particles have a lot of kinetic energy and therefore have enough space between them to move around. This is why gases can expand to fill the volume of their container.
Yes, they do. Sound waves move fastest through solids, less fast through liquids, and slowest through gasses. This is because the molecules of solids are closer together, while those of gasses are further apart, creating more space that the waves must jump to move.
Really fast.
Really fast.
Molecules are spaced farthest apart in the gaseous state because the particles have enough energy to move around and separate from each other. In a gas, the molecules are free to move in all directions and only come close together during collisions.
molecules move more in gasses gasses>liquids>solids
Its a definition thing. Gasses don't move more because they're hotter. Gasses that move more are defined to be hotter. Gasses move more when they aquire energy from somewhere and their increased motion is measured with a thermometer. And when the thermometer goes up we say the gas is hotter.
Gasses CAN move solids. Look up pneumatics
In a solid the atoms are tightly packed together and vibrate in place, in a liquid the atoms are loosely packed together and can move past each other, and in a gas the atoms are far apart and move freely and collide frequently.
no they do not. the particles in gasses are free to move
