What is it called when a solid changes into a liquid?
The process of a solid changing into a liquid is called melting. This occurs when the temperature of the solid reaches its melting point, causing the solid to transition into a liquid state.
Is evaporation liquid changes to a gas?
condensation. Here is a list for your future reference: gas to liquid: condensation liquid to gas: evaporation liquid to solid: freezing solid to liquid: melting these next two are rare but have been known to happen: solid to gas: sublimation gas to solid: deposition
What are the 4 phases that changes solid liquid gas and plasma?
There are five common state changes between the three common states of matter. They are melting (solid to liquid), freezing (liquid to solid), condensation (gas to liquid), evaporation (gas to liquid) and sublimation (solid to gas, gas to solid).
What are the two changes in matter that occur between a solid and a liquid?
not sure here but i think gas and plasma not sure tho
What is the process at which water changes physical state?
liquid to solid is freezing (like putting water in the freezer and getting ice) solid to liquid is melting (leaving ice on the counter and it turns to water) liquid to gas is boiling (a pot of water on the stove) or evaporation (water slowly 'disappears' from a glass) gas to liquid is condensation (water on the outside of your cold glass on a warm day) solid to gas is sublimation (dry ice)
Does the temperature of a solid change when is starts melting?
No, the temperature of a solid remains constant as it melts. The energy added to the solid is used to break the intermolecular forces holding the solid together, rather than increase its temperature. This process is known as the latent heat of fusion.
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 heat change is there in liquid to gas change?
Type your answer here... evaporation
If an ice cube is placed in a pot that is heated what will happen after it has melted is it a chemical or physical change?
When ice melts and becomes a liquid it is a physical change. When the liquid boils and becomes gaseous it is a physical change. It is a chemical change when the molecular structure has been changed in some way, here it has not.
What two liquids form a solid?
a solid has high intermolecular force of attraction, so if the thermal energy is supplied to the solid, the randomness of the molecules increases and it thus decreases the force of attraction and hence converts into a liquid.
To change from a solid to a gas needs what to happen?
you need to heat the material to its melting point and then to its boiling point eg water's freezing point and melting points are respectively at zero. To melt water ypu would have to heat it up to at least 0 deg C, to change the liguid into its gaseous state you would have to heat it up to waters boiling point which is 100 deg C etc
How is heat of fusion used to protect against frost damage?
If an orchard is threatened by frost because of a sharp dip in temperature, we can turn on the sprinklers to warm the orchard. Two things are at work here. First, ground water is going to be cold, but not nearly as cold as air at freezing. Water at 45 degrees will release heat energy into the blooms of the fruit, which are sitting in air at just above freezing. It is not uncommon in orchards to be able to lift the temperature a couple of degrees by turning on the pumps and sprinklers. Water collecting on the blooms might still freeze, but as liquid water changes into solid water (ice), it give up energy to do so. This is the heat of fusion (or standard enthalpy of fusion), and the heat released when water changes state from liquid to solid will "go" somewhere, and the blooms will collect it. This helps stave off frost damage.
