Although the three states of matter are solid, liquid, and gas, not all substances seem to fit perfectly into one of these groups. Take a look at the substance below and see if you can decide whether ...

Unlike solid-liquid or liquid-gas transitions, this transformation is less intuitive. It involves differences in density and molecular organization between the two phases. In water's case ...

"By measuring how these condensates change from liquid to solid in living systems, we can better understand how diseases like Parkinson's develop and progress," said Zheng Shi, an assistant ...

Once again, the particles in a gas hit the walls of the container more often, causing the pressure to rise. Most substances can exist as a solid, liquid or gas. They can change state, usually when ...
