Why is heat energy stored as potential energy while vaporisation?
During vaporization, heat energy is stored as potential energy because the energy is used to break the intermolecular forces holding liquid molecules together. This potential energy allows the molecules to transition from a liquid to a gaseous state without a change in temperature.
What is the origin of force of friction?
Friction is a force that originates from the interactions between the molecules of two surfaces in contact. When these molecules come into contact, they create resistance to the motion of one surface across the other, resulting in friction.
Is ground friction greater than air friction?
Yes, ground friction is typically greater than air friction due to the surface contact and interacting molecules, which slows down objects more effectively compared to the sparse air molecules encountered in the atmosphere.
How does Friction occur in liquids?
Friction in liquids is caused by the interaction of molecules as they move past each other. The viscosity of a liquid, which is its resistance to flow, determines how much friction there is in the liquid. When molecules in a liquid move, they create resistance against each other, leading to friction.
Why is friction greater in water?
A gas like air, is marked by lower density of molecules than a solid or liquid. Friction is caused by molecules bumping into eachother, so the more molecules there are to run into, the higher the friction. So, air has less molecules per cubic foot and therefore has less density and less friction than water.
What happens to the potential of the molecules in a reaction?
the potential energy of the molecules changes during a reaction.
What happens to molecules during photosynthesis?
It gets released into the Atmosphere.
Why is heat energy stored as potential energy while vaporisation?

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..
What happens to the number of molecules of the gas when it is compressed?
When a gas is compressed, the volume it occupies decreases, causing the gas molecules to be closer together. The number of molecules remains the same, as no molecules are added or removed during compression.
Does a gas with large molecules has friction between its molecules?
A gas with large molecules has friction between its molecules because they are constantly coming into contact with each other. This is a normal process which does not alter the overall composition or characterises of the gas.
What causes friction in a machine?
Rubbing of molecules.
What happens to the molecules during melting?
the order of the solid molecule is destroyed, the molecules can move more freely, while in solids the molecules vibrate in fixed point
What happens to the potential energy of the molecule in the reaction?
The potential energy of the molecules change during a reaction.

Why do molecules move faster when heated?
Because of friction
