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.
What is the kinetic energy in liquid?
Liquids have a larger kinetic energy than a solid but less than a liquid because they only contain enough kinetic energy to slip slowly over each other as appears to a solid where they are limited to vibrating around a fixed point and a gas where the move freely in all directions at high speeds.
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.
When a substance changes from liquid to solid what is the energy?
The energy released is called the latent heat of fusion. This energy is needed to overcome the attractive forces between the particles of the substance to allow them to transition from a liquid to a solid state.
What happens to the energy level as a substance moves from the solid to the liquid and eventually to the gaseous state?
the amount of motion of each molecule increases. i.e the amount of disorder increases. since the motion is increasing as an object gets converted from solid to liquid to gas, the energy level increases.
How do you describe each phase change?
Endothermic phase changes - the substance is gaining energy (being heated) and the molecules are getting more active.- solid to liquid: melting- liquid to gas: vaporization- solid to gas: sublimationExothermic phase changes - the substance is losing energy (cooling) and the molecules are slowing down.- gas to liquid: condensation- liquid to solid: freezing- gas to solid: depositionMemory helper: exo is like exit, and the heat energy exits the substance during an exothermic phase change.
How are the paricles in a liquid?
Particles in a liquid have only a small amount of space between each other. They have more energy then solid particles but less energy than gas particles. Particles in liquid roll over each other this is what causes water to flow.
Determine how energy is related to change in state?
Energy is used to do work against in separating the mutually attracive atoms or molecules from each other to change them from solid into liquid and from liquid into gaseous state.
At what point does a solid become a liquid?
The point at which a solid becomes a liquid is known as the melting point. This differs depending on the solid.
Why are particles of gas so hard to contain?
Because gas particle are all sperated unlike liquid and solid so they are hard to contain. hard to contain because they are not close to each other they all seperate
How each state changes and what it is called?
* solid to liquid: melting* liquid to solid: freezing* liquid to gas: vaporization* gas to liquid: liquefaction* solid to gas: sublimation* gas to solid: deposition
What is the state of matter when a solid turns to liquid?
The state of matter changes from a solid to a liquid during the process of melting. In this phase transition, the solid's particles gain enough energy to break free from their fixed positions and flow past each other, resulting in a liquid state.
