Our universe is made up of matter. Matter is found within our bodies and around our close environment too. It occupies space within our observable sight and at molecular levels we cannot simply see with our bare eyes. Curious minds have been investigating concepts relevant to matter since the fifth century, giving rise to interesting theories including those of ancient Greek philosophers like Empedokles. He suggested that the roots of matter were ‘eternal and invariable’ consisting of water, air, fire and earth. The concept of Plato’s bodies was later developed to improve representations of Epedokles’ “roots of matter”. This would, in turn, support many arguments regarding the constituents of matter forming what eventually gave rise to modern-day atomic theory. Learn about the scientific experimentation and proofs that made modern-day atomic theory outlive other theories regarding matter.

This course explores the chemistry behind the existence of matter in its different states of solid, liquid and gas. It maintains its characteristics of occupying space (or having volume) and having weight. Each state of matter has its own unique properties that distinguish it from the others. The properties of each state are analyzed in this course together with their relationships and expected effects from varying forces or energies. You will learn about common variables affecting gas pressure including volumes of the containers used, temperature of gasses surrounding us, and the number of measurable gas molecules in containers. In addition, the different states of matter have varying factors of the strength of attraction between molecules. For instance, liquids have different types and strengths of attractions to one another following common intermolecular forces involving dipole and induced dipole forces.

Science students interested in increasing their chances of passing their high school chemistry exams should enroll in this free online course. Your proficiency in calculations involving ideal gas laws, Dalton’s law, Charles’s law, Boyle’s law, Avogadro’s law, and Gay-Lussac’s laws will be improved. You will also learn about calculations related to various chemical solutions and their molar concentrations. The material covers molecular forces, subatomic particles, and the basic aspects of chemical bonding. Do you want to understand what happens when matter changes from one form to another? Start this course today to comprehend the chemical concepts of matter relevant to their different states alongside the intermolecular forces at play.
