The three states of matter can be represented by the particle model. This model explains the properties of substances in their different states, as well as changes of state. Changes of state ...

Physical chemists are focused on understanding the physical properties of atoms and molecules, the way chemical reactions work, and what these properties reveal. Their discoveries are based on ...

See the study guide on the three states of matter to see how bonding and structure are related to the properties of substances. Energy must be transferred to a substance to make it melt or boil.

Chemical physics applies physical methods and theory to study molecular and collective properties of matter. The focus is on understanding complex phenomena from gas phase molecular dynamics, to ...

Chemistry is a branch of science that involves the study of the composition, structure and properties of matter ... for instance through chemical reactions. Ion exchange membranes with tailored ...
