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.
What happens when a solid a liquid and gas when it changes its state?
When a solid changes to a liquid, it melts and gains more kinetic energy. When a liquid changes to a gas, it evaporates and gains even more kinetic energy. When a solid changes directly to a gas without passing through the liquid state, it is known as sublimation.
When liquid changes to gas phase the following occurs?
When a liquid changes to a gas phase, the intermolecular forces between the molecules are overcome, leading to an increase in kinetic energy and individual molecules escaping from the liquid's surface. This process is known as evaporation or vaporization and requires energy in the form of heat.
What happens to the molecules in a glass of water as the water evaporates?
The energy of a molecule is made up of potential and kinetic. so as kinetic increases, potential decreases. Also as when molecule is in gaseous state, the distance between molecules is much greater than that in a liquid, so the potential energy is less as a gas NOTE a molecule has potential energy when it is a certain distance away from its equilibrium position between adjacent particles during its vibrations in a liquid. Kinetic energy is motion energy. SO in there is less attraction between adjacent molecules, so potential energy is less.
When a substance changes from a liquid to a gas energy is . When a substance changes from a gas to a liquid energy is .?
When a substance changes from a liquid to a gas energy is absorbed. When a substance changes from a gas to a liquid energy is released.

Does potential increase or decrease when gas changes to liquid?
The potential energy of a substance decreases when it changes into a liquid. This is because it's losing the heat energy it had when in gas form to become liquid.
Does potential energy increases or decreases when gas changes to liquid?
The potential energy of a substance decreases when it changes into a liquid. This is because it's losing the heat energy it had when in gas form to become liquid.
Does kinetic energy increase or decrease when a liquid changes to a gas?
Kinetic energy increases when a liquid changes to a gas because the molecules in a gas have higher average kinetic energy compared to those in a liquid. When a liquid evaporates and becomes a gas, the molecules gain more energy and move faster, increasing their kinetic energy.
What are two changes in state that require the release of latent potential energy?
Two changes in state that require the release of latent potential energy are condensation, where gas turns into liquid and releases energy, and freezing, where liquid turns into solid and releases energy.
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.
When solid and liquid phases are in equilibrium which phase solid or liquid contain the greater amount of energy?
The answer depends on the specifics of the question. The idea though, is that when they are in equilibrium, both the solid and the liquid should have the same amount of energy PER MOLECULE. The fact that there is a solid component and a liquid component means that either the solid is melting or the liquid is freezing. In most situations, that means that the temperature of the whole mixture is constant. Another idea is that the energy in the molecules can either be kinetic or potential energy. Basically, the more kinetic energy PER MOLECULE an object has, the higher the object's temperature. Furthermore, the more potential energy PER MOLECULE that the object has, the further apart the molecules are from each other. Combining these ideas, here are a few possible answers to your question. 1. There is more solid than liquid. On average, the solid's molecules have the same kinetic energy as the liquid. The solid, having more molecules, has more kinetic energy total. The liquid has more potential energy in total. The solid has more overall energy. 2. There is more liquid than solid. On average, the liquid's molecules have the same kinetic energy as the solid. The liquid, having more molecules, has more kinetic energy total. The liquid also has more potential energy in total. The liquid has more overall energy. 3. There are equal amounts of liquid and solid. On average, the liquid's molecules have the same kinetic energy as the solid. The liquid has equal kinetic energy as the solid due to the even split. The liquid also has more potential energy in total. The liquid has more overall energy. These three are the main possibilities, and as can be seen in the details, the answer depends on the relative amounts of liquid and solid.
Why is energy required for phase change?
Energy is required for phase change because it involves breaking or forming intermolecular bonds. When a substance changes from solid to liquid or liquid to gas, energy must be added to overcome the forces holding the molecules together. Similarly, when a substance changes from gas to liquid or liquid to solid, energy is released as the molecules form bonds.
What happens when a solid a liquid and gas when it changes its state?
When a solid changes to a liquid, it melts and gains more kinetic energy. When a liquid changes to a gas, it evaporates and gains even more kinetic energy. When a solid changes directly to a gas without passing through the liquid state, it is known as sublimation.
When a gas changes into a liquid it is called and the speed of the molecules is?
When a gas changes into a liquid, it is called condensation. During condensation, the speed of the gas molecules decreases as they lose energy, allowing them to come together and form a liquid.
When a gas changes into a liquid it is called condensation and the speed of the molecules is increased or decreased?
When a gas changes into a liquid, it is called condensation. The speed of the gas molecules decreases during condensation, as they lose kinetic energy and come closer together to form a liquid.
When liquid changes to gas phase the following occurs?
When a liquid changes to a gas phase, the intermolecular forces between the molecules are overcome, leading to an increase in kinetic energy and individual molecules escaping from the liquid's surface. This process is known as evaporation or vaporization and requires energy in the form of heat.
