The kinetic theory of matter states that matter is made of particles whose speed is dependent on what?
The kinetic theory of matter states that matter is made of particles whose speed is dependent on their mass and temperature. The kinetic theory states that particles in matter are always in motion.

Pythagoras
When was the atomic theory discovered?
Leucippus is a mysterious figure whose exact dates are unknown - some say he never existed - but is still considered the be the founder of the Atomistic theory. Democritus was born 460 B.C. and died 370 B.C. He was a disciple of Leucippus and both men are credited with the atomistic theory.
