It does not matter if a substance melts, freezes, boils, evaporates, condenses or sublimates - the mass does not change. These changes in state are called physical changes because the process can ...

There are three main states of matter: solid, liquid and gas. When a substance changes state, this is a physical change because no new substances are produced and the change is reversible.

The behaviour of the tiny particles in each case helps explain the properties of each state of matter at the everyday scale. Freezing, boiling, condensing and other changes of state can also be ...

Phase transitions, shifts between different states of matter, are widely explored physical phenomena. So far, these ...

Chinese researchers observed a novel quantum state of matter ... for exploring novel forms of matter, making it an essential tool for studying the microscopic physical mechanisms of strongly ...

Physical properties vary with the amount of heat and the amount of dissolved matter contained in the water, as well as the ambient pressure. Important state variables ... of the change in volume ...
