Is there any other state?
First, we will explain the four already known states:
Solid: This is the state, in which the matter has not much kinetic energy and the particles are packed so they vibrate and they are put in order.
Liquid: When a solid gains energy, it becomes a liquid, and that process is called melting. A liquid has more energy than a solid but not enough to let particles move freely, so they are still in contact. When a liquid cools down, it becomes again a solid, and this is called solidification.
Gas: When a liquid absorbs heat, it becomes a gas, this is called evaporation and the inverse process is called condensation. The gases have lots of energy and the particles move freely and randomly. A solid can become a gas, but when it gains lots of energy very quickly, this is called sublimation and the inverse process is called deposition.
Plasma: is when a gas gains more energy and its electrons move freely from the atoms. The Sun is an example of plasma.
Interview with Dr. Faustino Feced Valverde
- Good afternoon.
- We asked you to come to ask you some questions like, are there any other states of matter as well as the four we already know about ?
- Yes, of course, apart from the four essential states, we think that are eight at least.
- Can you talk to us about some of those states?
- Yes, about ten years ago in the University of Colorado, some scientists created the first matter in the fermionic condensate state.
- What's this state like?
- They are fermionic particles cooled down to temperatures which are very near to the absolute zero. It is closely related to the Bose-Einstein condensate. We also discovered superfluids and superconductivity. The superfluid phenomenon is helium cooled down to a temperature very near to zero, so the helium atoms, which are bosons, have very little energy and they lose their viscosity so they can have an infinitely thin surface. On the other hand, superconductors have no electric resistance. Then, there is also the supersolid, which is a solid that both behaves like a solid and like a liquid at the same time. And that's all for the moment.
- Thank you Dr. Faustino for coming to The New Pork Times.
- Thank you for inviting me.
