Quarks are the particles that make up protons and neutrons. There are no particles, as far as we know, that make up electrons.
atomic particles
When a solid is heated its particles melts and change into liquid
no melting is a physical process
Molecules make up a compound.
The materials that make up noctilucent clouds are tiny water Ice crystals and dust particles.
Scientifically speaking, the ice is probably melting because of the particles in the air/water/wherever the ice is. The particles in the air speed up the particles in the ice causing it to melt.
An ice cube is just frozen water. When an ice cube melts it becomes water. Eventually, the water will evaporate.
because it bonds with the particles
The names of the particles that make up soil from the smallest to the largest particles are clay, silt, and sand.
Particles that make up matter are in a state of constant motion.
Quarks are the particles that make up protons and neutrons. There are no particles, as far as we know, that make up electrons.
Loosen particles
The same particles of matter that make up a solid are also the same particles of matter that make up a gas or a liquid. Basically matter consists of atoms. At the simplest level, the particles of atoms are electrons, protons and neutrons.
Ice melts because the atoms around the ice are moving faster (because they are warmer). So the faster moving atoms bump into the slow ones (the ice), and make the slow particles move faster a little bit at a time. and the slow particles make the fast ones slow down a little bit. Until all particles are moving the same speed. this is how ice melts.
no Ice particles fall from the sky but Ice crystals form on the ground.
Clouds that are very high up, where it is very cold, are made up of ice crystals. For example, a cirrus cloud.
