The latent heat of fusion is the heat required to change the solid from solid to liquid state without any change in temperature. The latent heat of fusion of ice is 336000 J/kg. While Latent heat of vaporization is the heat required to change the liquid from liquid to vapor state without any change in temperature.

What is vaporization physics?
vaporization, conversion of a substance from the liquid or solid phase into the gaseous (vapour) phase. If conditions allow the formation of vapour bubbles within a liquid, the vaporization process is called boiling. Direct conversion from solid to vapour is called sublimation.
What is latent of fusion and vaporization?
The latent heat associated with melting a solid or freezing a liquid is called the heat of fusion; that associated with vaporizing a liquid or a solid or condensing a vapour is called the heat of vaporization.
Is vaporization a melting or fusion?
Solids can be heated to the point where the molecules holding their bonds together break apart and form a liquid. The most common example is solid ice turning into liquid water. This process is better known as melting, or heat of fusion, and results in the molecules within the substance becoming less organized.
How do you use heat of fusion and vaporization?
What is vaporization explain with example?
When a liquid changes form into a gas, the process is called vaporization. You can watch vaporization when you boil a pot of water. Vaporization happens in two ways: evaporation and boiling. Evaporation occurs when sunlight shines on water until it changes to vapor and rises into the air.
What’s an example of vaporization?
Vaporization Examples Opening a sealed bottle of water and leaving it out for days results in the evaporation of some water particles. The surface of a water puddle evaporates during the day. Water is turned into steam when it comes to boiling. Examples: boiling water for tea, boiling pasta water, etc.
What is the example of vaporization?
Examples of Vaporization in Our Daily Life Industrially, salt is recovered from sea water by the process of vaporization. Wet clothes are dried up due to the process of vaporization. The process is used in many industrial processes for separating the components of a mixture.
What are the types of vaporization?
There exists two types of vaporization: evaporation and boiling. Evaporation is a surface phenomenon and only occurs on the phase boundary between the liquid and the gaseous phase.
What is the difference between vaporization and diffusion?
Answer: Evaporation occurs at temperatures below boiling point when kinetic energy of molecules in water is sufficient them plumment out of water surface into the atmosphere increase the vapor pressure. … Diffusion is the movement of molecules from a region of higher contentration to lower concentration.
What is the difference between vaporization and boiling?
Boiling is a rapid and fast vaporization of a liquid when it is heated at its boiling point. Vaporization is a process of converting a substance from its liquid or solid form into a gaseous form.
What is latent of vaporization?
Similarly, the latent heat of vaporization or evaporation (Lv) is the heat that has to be given to a unit mass of material to convert it from the liquid to the vapor phase without a change in temperature.
Why is latent heat of vaporization higher than fusion?
The latent heat of vaporization is higher than the latent heat of fusion since gas molecules have the largest intermolecular space and the force of attraction between the molecules is almost negligible. Therefore, more energy is required to convert liquid to gas.
What is the latent heat of fusion called?
Latent heat of fusion, also known as enthalpy of fusion, is the amount of energy that must be supplied to a solid substance (typically in the form of heat) in order to trigger a change in its physical state and convert it into a liquid (when the pressure of the environment is kept constant).
Why is melting called fusion?
This phenomenon is called fusion because when two separate solid objects made from the same substance are melted, they can get mixed together into a new one (they fuse). This can also apply to different substances, like alloys from different metals or mixtures of alcohol and water, or different waxes and oils.
Is fusion solid to liquid?
Fusion is the process of converting a solid into a liquid. And, this phase transition occurs via the melting of the solid. The process is named as such because of the term heat of fusion refers to the energy a substance requires to convert into its liquid phase at the melting point.
Does fusion mean melting?
Melting, or fusion, is a physical process that results in the phase transition of a substance from a solid to a liquid. This occurs when the internal energy of the solid increases, typically by the application of heat or pressure, which increases the substance’s temperature to the melting point.
Is fusion freezing or melting?
Fusion is used for freezing as well as for melting. Freezing means change of liquid to solid at fixed temperature, and melting is nothing but change of solid to liquid at fixed temperature. The word “Fusion” is used for both the processes i.e. for melting as well as freezing. Q.
What is meant by heat of fusion?
The heat of fusion is the quantity of heat necessary to change 1 g of a solid to a liquid with no temperature change (Weast, 1964, p. F-44). It is also a latent heat and is sometimes called the latent heat of fusion.
What is fusion in states of matter?
A chemical that exists in its liquid state can be changed back into a solid state in a process known as fusion, which is more commonly-known as “freezing.” Melting and fusion are complementary phase changes, because both relate the same states of matter.
What are 5 examples of vaporization?

- Ironing of Clothes.
- Melting of Ice Cubes.
- Preparation of Common Salt.
- Evaporation of Nail Paint Remover.
- Drying of Wet Hair.
- Drying up of Different Water Bodies.

What is heat of vaporization in physics?
latent heat, also called the heat of vaporization, is the amount of energy necessary to change a liquid to a vapour at constant temperature and pressure. The energy required to melt a solid to a liquid is called the heat of fusion, and the heat of sublimation is the energy…
What are 2 ways for vaporization to occur?
Vaporization (or vaporisation) of an element or compound is a phase transition from the liquid phase to vapor. There are two types of vaporization: evaporation and boiling. Evaporation is a surface phenomenon, whereas boiling is a bulk phenomenon.
Why does vaporization occur?
The temperature increase causes molecules to move quickly, and this motion breaks the intermolecular bonds between the atoms. As these bonds are broken, the molecules and atoms separate and spread out, which causes them to vaporize, or turn into a gas.
What is it called when liquid turns into gas?
At a certain temperature, the particles in a liquid have enough energy to become a gas. The process of a liquid becoming a gas is called boiling (or vapourization), while the process of a gas becoming a liquid is called condensation.
