Much like solids, liquids (most of which have a lower density than solids) are incredibly difficult to compress. In a gas, the particles have a great deal of space between them and have high ...

and the forces between the particles are different in solids, liquids and gases. The arrangement, movement and spacing of the particles explain many of the properties of solids, liquids and gases.

The ways in which particles, such as sand or liquid droplets ... you probably noticed the amount of wasted space between them all, especially if they're all the same size. But the more varied ...

“The magnetic particles here have two roles,” said Prof ... As seen in the video above, the robot can quickly change between its solid and liquid phases to escape tight spaces. Additional mobility and ...
