What does the kinetic theory describe?

Answer 1

atoms are in constant motion, collisions of atoms can cause chemical changes if there is enough energy involved. Increases in temperature causes atoms/molecules to have more kinetic energy, which can cause increases in reactions.

Answer 2

I'm not sure if this is what you are looking for but to explain how gasses work scientists have come up with the kinetic theory of gases. The word 'kinetic' refers to the constant rapid movement of the particles when they are in gas phase. Basically it follows the following: • Gases consist of tiny particles (atoms for noble gases and molecules for all other gases) moving in rapid, random, straight-line motion until they collide with one another or with the walls of a container. • Collisions between particles or with the walls of the container are perfectly elastic (no energy is lost in the collsions). • The size of the particles is negligible compared to the size of the container in which they are moving. It can be assumed that each gas particle has mass but no volume. Thee distances between the particles are very large compared to the size of the particles themselves. • Any attractive or repulsive forces between particles in the gas phase are negligible. • The average kinetic energy of the particles increases as the temperature of the gas increases. Since the mass of the particle does not alter, and kinetic energy is given by the expression KE 5 ½ mv2, the particles must move faster as the temperature increases. In any sample of a gas at a given temperature, the particles are not all moving at the same velocity. They have a range of velocities, with some moving slower than average and some much faster You can use this to relate to both solids and liquids, and it is for IDEAL gasses, not real ones. More info is in any chem book, like Chemistry For WA 1. Where this info is from.

Answer 3

atoms and molecules are constantly in motion

Answer 4

theory that explains the properties of matter in terms of the particles of matter always being in motion.

Answer 5

It states that all matter is made up of particles that are in constant, random motion.
