Question

Based on the kinetic molecular theory (KMT), which statement is true?
The particles of matter are do not move.
Matter is composed of very small particles.
The particles of matter have zero kinetic energy.
Matter is made up of only charged particles.

Answer 1

Statement 1 is false because heat is the movement of molecules.

Statement 2 is true because matter is composed of elementary particles which are VERY small.

Statement 3 is false because the kinetic energy of a particle determines its heat and it is impossible for a particle to be completely motionless.

Statement 4 is false because neutrons do not have a charge and make up a large portion of all matter.
