Light dark matter, in astronomy and cosmology, are dark matter weakly interacting massive particles (WIMPS) candidates with masses less than 1 GeV. When a certain temperature threshold unique to each substance in the universe is crossed, a phase change will result, changing the state of the matter. for example:- Chairs, bricks, almonds, air, lemon water, cold drinks, glass, atom, molecules, etc., but smell, feelings, thoughts, and emotions like love or hate, are not examples of matter because they do not occupy space in its surroundings and also . What happens to the speed of the particles when you change the temperature to colder? Suppose you move the free end of a rope up and down to create a wave. Solid to liquid change : Melting Defination : The process in which a solid substance changes into a liquid on heating, is called melting (or fusion). Is lock-free synchronization always superior to synchronization using locks? A liquid (NOT WATER, IT IS A SPECIAL CASE) has lower density than the crystal because the molecules are moving around a lot and "need more space". As a result, the interparticle force of attraction between particles decreases, and particles become unattached from their positions and free to travel. But considering water(as pointed out by Ivan), it actually shows the reverse trend ie., density of ice < denisty of water. When a liquid is heated, the heat energy makes its particles move even faster. The relationship between temperature and kinetic energy is important to understand because it affects so many everyday phenomena. 5 Why does the temperature of a cube increase with speed?
