Solids, liquids and gases. In a solid like this brick, the particles are regularly arranged touching their neighbours and move only by vibrating. This explains why solids have a fixed shape. In a ...

The liquid-gas interface trapped on underwater solid structures has multiple excellent properties, such as drag reduction, anti-biofouling, and anti-corrosion, and that is why it has a promising ...

Elisa Oviedo transforms water from liquid to solid. Elisa Oviedo and her niece change water from liquid to solid using a freezer. Then they heat water up on the stove until it turns into gas. Elisa ...
