Physics IX Notes Chapter 7 Properties of Matter physics class 9th notes for kpk all board. Q.1 explains the kinetic molecular model of matter?kinetic molecules model of matter:- according to this theory matter consists of small particles called modules. Modules are made of a small particle called atoms. These molecules are always in a state of motion. The motion may be linear, vibrational or rotational and this motion is increased with an increase in temperature, there is a force of attraction between the molecules which depend upon the distance between them. Their kinetic energy is due to their motion and potential energy is due to the force of attraction between them.explains the states of matter on the bases of a molecular model of matter?State of matter explained below on the bases of molecular theory? Solids:- solids have a definite shape and a definite volume. In solids, molecules cannot transfer from one place to another. Their molecules perform the vibratory motion. Their molec...
