What happened to the potential energy of the liquid molecules as they evaporated?
When liquid molecules evaporate, the potential energy of the molecules decreases. This is because the molecules overcome intermolecular forces and move from a more ordered state (liquid) to a less ordered state (gas). As the molecules gain kinetic energy during evaporation, the potential energy decreases.
Evaporation involves thr process of changing water molecules from the liquid state into?
Evaporation involves the process of changing water molecules from the liquid state into water vapor, which occurs when heat energy is applied to the liquid water, causing the molecules to gain enough energy to escape into the air.
What change from the gas state to liquid state is called?
The transition from the gas phase to the liquid phase is called "condensation."
What is the relationship between the kinetic energy of molecules and their pysical state?
The kinetic energy of molecules is higher in the gaseous state compared to the liquid or solid state. This is because the molecules in a gas have more freedom of movement and higher average velocities. As a substance transitions from a solid to a liquid to a gas, the kinetic energy of the molecules increases.
How do molecules in a liquid state move around indefinitely without losing energy and stopping?
The molecules are kept in the liquid state by being above freezing temperture and below the vaporization temperture. They take the energy needed to stay in this form from their surroundings and if their surroundings are above freezing temperture and below vaporization temperture they will stay in the liquid state theoretically forever.

What is the process by which molecules at the surface of a liquid absorb enough energy to change to the gaseous state is called?
The process by which molecules at the surface of a liquid absorb enough energy to change to the gaseous state is called evaporation. This occurs when the kinetic energy of the molecules overcomes the intermolecular forces holding them in the liquid state.
Why is kinetic energy more in liquid state?
Than in ??what?? state Kinetic energy is greater in liquid state because the liquid substance is moving. If the kinetic energy was less than in liquid state, the object of the state would become solid.
Why polar gases liquefy easily than non polar gases?
Non polar gases have very low critical temperature. Non polar gases have weak forces of attraction between their particles. They cooled to very low temperature. Polar gases have high value of critical temperature. The inter molecular forces are very strong . So polar gases have better tendency to be converted into liquid.

What is the process by which molecules at the surface of a liquid absorb enough energy to change to a gaseous state?
The process is called evaporation. Molecules at the surface of a liquid gain energy from the surroundings, typically heat, causing them to overcome the intermolecular forces holding them together. Once they have enough energy, these molecules transition to the gaseous state and escape from the liquid surface.
Do molecules gain or lose energy from melting?
When matter melts (changes from a solid to a liquid state), its molecules move faster, meaning they are gaining energy.

What is happening to the molecules during the condensation process?
During condensation, molecules are transitioning from a gaseous state to a liquid state as they lose energy and come closer together. This process involves the conversion of the kinetic energy of the molecules into potential energy as they form stronger intermolecular forces, resulting in the formation of a liquid.
What is needed for the molecules in a solid state to change into the liquid state?
In order for molecules in a solid state to change to a liquid state, the substance needs to be heated. An increase in temperature causes more molecular movement (this leaves more space between each molecule) which results in what we see as the physical change from solid to liquid and then eventually liquid to gas.
