The molecules state of being changes from that of gas to that of being a liquid. The gaseous substance molecules has much more energy in it. But as the energy escapes or slows down, the molecules stop moving so much and there for bond better causing gas to change to liquid; and liquid to change to a solid. Solid particles are those whose atoms and molecules move very slightly and contain little energy.
It depends on the substance. If it is a molecular compound made of molecules (groupings of atoms covalently bonded to each other), then going from a liquid to a gas does nothing to the atoms. All that happens is that the intermolecular forces between the molecules are broken and the molecules are separated from each other, but the atoms in the molecule remain bonded to each other the same way that they were in the…
How does the potential energy of water molecules change as water changes from a liquid to a solid or gas?
When a substance changes from a liquid to a gas, its molecules expand and move farther apart from each other. In other words, intermolecular space between the molecules increase. Since changes in states of matter (also called interconversion) are always physical changes, there is no difference in the chemical contribution and no new substance is formed. Thus, there is no discovered difference in the atoms.
The faster the molecules of a substance are moving, the warmer that substance is, because temperature is really a measurement of the average kinetic energy of the molecules in a substance or object. For a substance to evaporate, or change from a liquid to a gas, it has to become warmer. That means that the kinetic energy of the molecules increases.
Which describe the changes that molecules undergo when heat is applied during a phase change and a single phase?
There are several phases of change that occurs when heat is applied, this is also known as a change of state. Heat changes the bond between molecules and either changes the state from a solid to a liquid (fusion), liquid to solid (freezing), gas to liquid (condensation), liquid to gas (vaporization), solid to gas (sublimation), or gas to solid (deposition).
