It turns out that any material, no matter what it is made of, can exist in one of three forms: solid, liquid or gas. These are categories of stuff that have certain observable properties.

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. Ionic compounds - AQA ...

Students will learn how to categorize matter as either pure substances or mixtures. Students will apply tests, based on physical properties of matter samples, to determine whether a mixture is ...

Dark matter could also explain certain optical ... Many scientists have also pointed out that the known properties of dark energy are consistent with a cosmological constant, a mathematical ...

New research suggests that black holes may actually be "frozen stars," bizarre quantum objects that lack a singularity and an ...

Although it would be hard to explain the properties of a tornado in terms of the physics of electrons and quarks, I see this as a matter of calculational impasse, not an indicator of the need for ...

Most of the matter in our universe is invisible. We can measure the gravitational pull of this “dark matter” on the orbits of stars and galaxies. We can see the way it bends light around ...

Prof. Sebastian Loth and his team have captured atomic-level electron motion in solids with unprecedented spatial and ...

Scientists investigated a new two-dimensional form of matter known as Bose glass, which could help physicists study a concept ...

A new study by MIT physicists proposes that a mysterious force known as early dark energy could solve two of the biggest puzzles in cosmology and fill in some major gaps in our understanding of ...

Vacant and unsafe structures with garbage strewn across properties is leading to rodents entering livable, neighboring ...
