Document Summary
Physical science is any of the natural sciences dealing with inanimate matter or with energy as physics and chemistry. Physics is the study of matter, energy, motion and force. Chemistry is the study of matter and its properties. Matter is anything that has mass and volume. To understand the chemical ad physical properties of matter efficiently and systematically, we must use the scientific method: everything stars from observation. Ny observation, there seems to be a relation between temperature and the volume of a gas: we hypothesize that the volume of the gas is proportional to the temperature. We hypothesize that the volume of the gas is proportional to the temperature: we must test this hypothesis through an experiment. The information obtained in the experiment is called experimental data. Experimental data alone does not mean very much: we need to build a model (theory) that is consistent with the data. Experimental data seems to lie on a straight line.
