What happens to the particles in a substance when heat is added?

The solids were tightly compressed and held more energy together. For example, in rocks there are many atoms / molecules that bind them, then there is polystyrene foam. They are in a specific shape

The degree of compression of liquid is lower than that of solid. They fit into their container. For example, water does not have a clear shape and is suitable for that container. They are not clearly shaped

Gas is everywhere. Even without specific shapes, there is more space between them. Gas is usually in the air

Ice can pass through all three phases. First from solids, then to liquids (in the form of water), then to gases (by evaporation)

When particles are heated, space is formed. Atoms began to be "over excited" and began to move faster than usual. When this happens, energy is released in the form of heat, light and the like. Therefore, the kinetic energy increases, and the frequency of atomic collisions increases.

When heated to a substance, molecules and atoms oscillate faster. If the atom oscillates faster, the space between atoms widens. Particle movement and spacing determine the physical state of the material. The end result of increasing molecular motion is that the object expands to occupy more space. In the figure on the left, there are workers who are trying to reconnect two rails that are separated due to extreme cold. To solve this problem, the worker ignited the oil entry rope next to the truck. Fire heat will expand the truck so that they can reconnect again

Temperature is a measure of the amount of heat present in a substance. A common tool for measuring temperature is a thermometer. The theory of matter particles states that all substances are always moving, having spaces between them and consisting of small particles attracted to each other according to temperature. The particles move faster and further when heated and the particles become slower and closer when cooled. When packed with solid particles and moving slowly, faster and farther in the liquid particles, the particles are the fastest in the gas and completely separate from each other. This is because particles in the material swell due to heat, moving quickly, and the state changes.

Move the particles quickly "excites" nearby particles. If sufficiently heated, the movement of the particles in the solid increases and overcomes the bond holding the particles together. The substance changes from solid to liquid (melting). As the movement of the particles further increases in the liquid, the substance reaches a gas (evaporation) stage. Convection transmits thermal energy through gas and liquid. When the air is heated, the particles get thermal energy, allowing them to move faster and further, and carry thermal energy. Warm air will be denser and cooler than cold air. The cooler air moves down and replaces the already rising air. It heats up, heats up, and is replaced again by cooler air, forming a circulating flow called convection. These flows surround the room and heat
