What happens to the atoms when a substance changes state from a liquid to a gas?

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 liquid. In situations where you do not have molecules (just atoms attracted or bonded to each other) then vaporization does separate the atoms from each other. Examples might be vaporizing a metal like Mercury or a noble gas like xenon.

∙ 14y agoIf an atom of an element changes its state (solids, liquids and gases), then its chemical properties remain unchanged, however its physical properties change (the atoms either become more compact or loosely placed with changes in state).

∙ 11y agoWhen 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.

What happens to atoms of A substance when heat is added?
When heat is added to a substance, the molecules and atoms vibrate faster.
How can pressure change a liquid into a solid?
Liquid changes to gas when pressure is reduced and temperature is increased. When pressure on liquid is reduced, the inter molecular space increases and temperature increases the kinetic energy of the atoms. This changes liquid to gaseous state
Describe how particles change as they change state from solid to liquid?
Particles do not change when they change state from solid to liquid form. However, they will change behavior because they are completely still when they are solid and move faster when a liquid.
What will happen to the atoms or molecules of a substance when it condenses?
When a substance condenses, it turns from a vapor (gas) into a liquid. When this occurs, the atoms/molecules lose some kinetic energy, and don't move as fast. They also become packed closer together, and take up less volume.
What is the basic unit of matter?
The basic unit of matter is the atom.Every material object, or substance that can be touched and felt, is made up of atoms. Everything that is solid, liquid, or gas is made up of atoms. An atom's size is measured in pictometers (trillionths of a meter).
What happens to the atom when a substance changes state from a liquid to a gas?
atoms gain more kinetic energy, so they are moving so rapidly that the intermolecular attractions can no longer hold them in liquid form.
What happens the atoms when a substance change state from a liquid to gas?
Vaporization is what happens when a liquid is changed to a gas. When a gas is changed to a liquid it is called condensation.
What change occurs when a substance changes phase?
The atoms movement is either more free (liquid to gas) or more restricted (liquid to solid)
What happens to a substance when the space between the substances particles increase?
When atoms are separated the substance changes forms. Solid Liquid Gas Plasma These are a few of the forms. The substance becomes more fluid, more easily shaped and compressed. It is able to form new materials, and is easier to ignite.
What happens to a substance what the space between the substances particles increase?
When atoms are separated the substance changes forms. Solid Liquid Gas Plasma These are a few of the forms. The substance becomes more fluid, more easily shaped and compressed. It is able to form new materials, and is easier to ignite.
What happens when a substance changes state from liquid to a solid?
The molecules/atoms move far apart. As the separation between paricles increase, the state is changed. The temperature does not rise because the heat is used to overcome inter-molecular forces.
What happens to the molecular motion of a liquid as it freezes?
As the temperature of a liquid substance lowers, the molecules and atoms making up the substance slow down their movement. The also pack closer together, making the substance more rigid, turning it into a solid.
What happens to a substance when the space between the substance's particles increases?
When atoms are separated the substance changes forms. Solid Liquid Gas Plasma These are a few of the forms. The substance becomes more fluid, more easily shaped and compressed. It is able to form new materials, and is easier to ignite.
What happens when temperature of a solid reaches its melting point?
When a substance reaches its freezing point or boiling point, it also undergoes a physical change from one phase to another, changing some of its physical properties.
What is the difference between condensation and boiling?
Boiling : the temperature increases substance changes its form from liquid to gas atoms of the substance moves with the high kinetic energy by absorbing heat Condensing : the temperature decreases substance changes its form from gas to liquid atoms of the substance loses atomic kinetic energy by losing heat
What happens to atoms of A substance when heat is added?
When heat is added to a substance, the molecules and atoms vibrate faster.
What forms new substances by changing the arrangement?
Physical changes confer to the change in the physical nature of the substance. Atoms rearrange them to form a new substance identical to the previous one. Example - If you met a solid wax, you still get a wax, but in liquid form. The atoms of the solid wax rearranged themselves to form a new product (liquid wax) but the substance was same that is wax. So no new substance was formed.Source:
