Even so, the best example of this phenomenon occurs in nature and is the dew itself that we find on plants, walls and glass exposed to the night cold, in environments rich in humidity , or on the surface of the bathroom mirror after giving us a hot shower. The process contrary to condensation is evaporation or vaporization, in which heat energy is introduced into a body of matter in a liquid state, until it reaches its boiling point , from which the liquid begins to become vapor.
The sublimation and reverse sublimation are processes similar to the evaporation and condensation, respectively, except that the phase change of gaseous matter does not occur with the liquid but with the solid directly. That is to say that in sublimation, instead of converting a solid to a liquid and then to a gas, a solid is transformed directly into gas.
In reverse sublimation, a solid is obtained directly from a gas , usually in the form of crystals. For this process to occur, very specific atmospheric pressure conditions are required.

This would be vaporization. Condensation is the reverse process- the change of a substance from the gas phase to the liquid phase. Condensation is the change of the physical state of matter from gaseous phase into liquid phase, and is the reverse of vaporization. Condensation is the change of the physical state of matter from gaseous phase into liquid phase and is the reverse of evaporation. Condensation is the change of the physical state of matter from gas phase into liquid phase, and is the reverse of vaporization.
Pieces of dry ice become smaller during condensation. Phase change, condensation. The opposite phase change is condensation. Evaporation is the change in phase from liquid to gas. Condensation is the change in phase from gas to liquid.
Condensation is the phase change from gas to liquid. Condensation is a change of phase, from gas to liquid. Condensationis the change of the physical state of matter from gaseous phase into liquid phase, and is the reverse of evaporation. When the transition happens from the gaseous phase into the solid phase directly, the change is called deposition - the opposite of sublimation.

The phase change that accompanies water as it moves between its vapor, liquid, and solid form is exhibited in the arrangement of water molecules. Water molecules in the vapor form are arranged more randomly than in liquid water. Evaporation, like melting or freezing, is an example of a phase change—a change from one physical form of a substance to another. During evaporation, energetic molecules leave the liquid phase, which lowers the average energy of the remaining liquid molecules.
Sample answer: Phase changes occur because of the energy of molecular motion. As heat is added to a solid, the molecules break out of their bonds and begin to move freely, causing the solid to melt.
As heat is added to a liquid, the molecules move faster and faster until they break free of the liquid and become a gas. A phase change is occuring; the liquid water is changing to gaseous water, or steam. On a molecular level, the intermolecular forces between the water molecules are decreasing. The heat is providing enough energy for the water molecules to overcome these attractive forces. Water must release energy to move from a higher to lower energy phase, i.
In each case, the energy released by the water results in a change in the internal molecular bonding structure. If you start with ice, then to form water, you add enough heat to break the intermolecular forces holding it in the solid phase.
If we are considering melting and boiling, the clear choice is boiling, which requires almost 7 times more energy than melting. Taking this information in hand we can see that that boiling needs approximately 6 to 7 times more amount of energy than in melting.
