At room temperature, atoms travel at roughly the speed of sound. Since at a given temperature, the average momentum of the molecules of different substances are the same and since momentum is mv (mass times velocity) a lighter atom or molecule is traveling faster than a heavier one. The lighter molecule has the same momentum (temperature) as the heavier molecule and so is moving faster.
The average speed of the particles in a substance is the definition of temperature.
Temperature is a measurement of the average speed of the particles in a substance.

Temperature
When we heat a substance, the energy absorbed is converted into kinetic energy of the particles in it. The faster the particles in it vibrate, move, collide, etc. the higher the temperatureof a substance.So the expected answer is Temperature
Entirely dependant upon the substance e.g. particles in gases travel at a much faster speed that liquids and faster still than solids.
