Question

(which of the following statements is the best description of the kinetic theory of matter)

matter is made up of electrons, which are in constant motion and have energy.

matter is made up of atoms, which are in constant motion and have energy

matter is made up of atoms which seldom move and do not possess energy

matter is made up of compounds, which are in constant motion and have energy

Answer 1

The correct option is B.
Matter is defined as anything that has mass and occupy space. The kinetic theory of matter states that all matters are made up of huge number of small particles which are in constant motion. These small particles are called atoms. Each atom has sub particles, which are electrons, protons and neutrons. The electrons are in constant motion orbiting the nucleus in which the protons and the neutrons are located. The electrons are able to move about constantly because they possess energy.

Answer 2

The statement that best describes the kinetic theory of matter is the one that explains that matter is comprised of atoms that are in constant motion and have energy. An atom is a basic unit of a chemical element and each time two atoms collide, energy is transferred.
