As pentane is boiled, the intermolecular bonds between molecules of pentane are broken. This makes pentane molecules free to move as they please and expand to fill any volume.

What happens to air molecules when air gets warmer?
At increased temperatures, atoms and molecules exhibit more kinetic energy. This energy shows up as "vibration" in the atom or molecule. Those atoms and molecules also move around more in the "situation" they're in. As a liquid or gas, those particles that make it up will move around more within the volume of that liquid or gas. In a solid, the atoms or molecules will "buzz" increasingly as temperature goes up.
What happens to energy when a liquid turns into gas?
When a substance is changing from liquid to gas, the energy, which is absorbed, causes the atoms (or molecules) to move at a higher rate of speed, so that they are not staying close together, like in the liquid state. So the absorbed energy increases the kinetic energy of the atoms (or molecules).
A nonsolid state of matter in which the atoms or molecules are free to move past each other as in a gas or liquid?
Matter only comes in three forms; solid, liquid and gas. There is no other form of matter that allows atoms or molecules to move about freely.
How are atoms related to molecules in a sample of a compound?
atoms are made of molecules and that is why they are related !
What is the movement of atoms in a liquid during a temperature changes both increases and decreases?
As temperature increases, the atoms will move around more energetically - moving on average faster. Translational speeds increase, rotational speeds of the molecules increase, and the magnitude of vibrations of the atoms about their bonds in molecules increase As temperature decreases, the atoms move around less energetically - moving on average slower. Translational speeds decrease, rotational speeds of the molecules decrease, and the magnitude of vibrations of the atoms about their bonds in molecules decrease
What happens if you add an atom to another atom?
it becomes a molecule. when you add molecules and atoms, they form matter.
What happens to particles when heat energy is absorbed during melting?
After heat energy is absorbed during melting the atoms and molecules start moving away from each other as the force of attraction becomes weak. At one point the atoms or molecules move so further away that the solid turns into a liquid.
How do molecules at the surface of a liquid enter the vapor phase?
When we add energy to a liquid, the place where the energy is absorbed is in the vibration of the links between the atoms of a molecule. At first, the atoms of the molecule draw apart from their peers, but eventually, the vibration becomes sufficient to overcome the surface tension of the liquid, and the molecule breaks free. The hottest molecules evaporate first.
What happens to the atoms in water when water boils?
The atoms speed up building up kenetic energy which forces them apart and that is what turns the liquid into a gas
What happens to atom and molecules when matter is cooled?
Nothing happens to the atoms within the molecules,but the molecules move around slower.
What happenes when a solid turns into a liquid?
When a substance is in liquid from and changes in to a solid it freezes. It is also called solidification
What happens to the particles during evaporation?
the state of matter changes from liquid to gas, so the molecules spread out.
What are liquids made up of?
The two elements that can be liquid at room temperature and pressure without being bonded to something else are bromine and mercury.

What is melting or boiling point?
The melting point is the temperature at which a solid changes phases into a liquid. This is a result of the highly structured atoms of the solid, which have very little kinetic energy beginning to gain energy and dissociate. The boiling point is the temperature at which a liquid changes into a gas. This happens when the atoms/molecules of a liquid gain enough kinetic energy to escape the liquid and move into the gaseous state.
What element's atoms form diatomic molecules as a liquid?
Bromine is the only element that is liquid and forms diatomic molecules Br2. Mercury is also an element and is liquid but is monoatomic.
What happens to the atoms or molecules of a substance when it boils?
the atoms and molecules will vibrate, causing the substance to heat up (friction causes heat, the molecules and atoms will rub together, causing friction). I hope this helped!!!!!n_n when a substance reaches its boiling point naturally the intermolecular force becomes weak and the substance gets converted from one form to another..
