The molecules of the substance gain thermal energy as a result of which they vibrate more energetically. When the molecules have acquired enough energy they escape from the solid and enter the gaseous phase. Incidentally, there is no requirement for there to be a liquid phase between the solid and gas.
The particles in the substance slowly separate and when the substance is a gas the particles are free, and are buzzing all over the place
The particles are affecting the form of a chemical substance and not turning into a new substance.
There are no chemical changes.
During freezing, free-moving molecules of a liquid substance align themselves into a gridwork and no longer freely move. They become essentially stationary, and the strong bonds between them are formed by the changes in temperature, and are strong in nature, preventing the movement of the molecules. As you take heat energy from the molecules, they are not able to move as much, and they form the gridwork that becomes a solid.
The temperature remain constant during the phase changing.
Its released or adsorbed. Its "physical" because no new substance(s) is produced.
When a substance changes from a solid to a liquid and vice versa, its density changes.
It can melt into a liquid, it can be juiced,
It can melt into a liquid, it can be juiced,
When a substance changes from a solid to a gas, called sublimation, it quickly becomes less dense.
-Solid and a liquid? -A liquid and a gas? -A solid and gas? from roop
The substance that changes is the hydrogen peroxide. After it reacts, it forms bubbles of oxygen and water.
The temperature remain constant during a change of phase.
It can melt into a liquid, it can be juiced,
The particles of the substance gain kinetic energy as they absorb heat energy. Eventually there is enough kinetic energy for the particles to escape the liquid phase, forming the gas phase.
Vaporation takes place when the particles in a liquid gain enough energy to move independently forming a gas. if anyone has more info please add it. Thank you
The substance absorbs the heat of fusion. The temperature does not go up, but the form of the substance changes.
