The amount of energy involved in melting a substance without changing its temperature is called the?
It is called the enthalpy of fusion of a substance, also known as (latent) heat of fusion.
Which heat changes the state of a substance without changing its temperature?
both the heat of fusion and the heat of vaporization
Why is heat energy needed to melt a solid. What is this heat energy called?
the energy that goes into changing a substance from a solid to a liquid (melting) is called the latent heat of fusion.
Define latent heat of fusion and latent heat of vapourisation?
Latent heat of vapourisation can be define as the rate by which water is heat to vapourise, it has a difference with evaporation because evaporation occurs directly when the water start heatin while vapourisation always start in a specific temperature
Calculate heat of fusion?
The heat of fusion is:Q = specific heat x mass
What a substance does when it releases heat of fusion?
It explodes
The amount of energy involved in melting a substance without changing its temperature is called the?
It is called the enthalpy of fusion of a substance, also known as (latent) heat of fusion.
The amount of heat needed to melt one kilogram of a substance?
heat of fusion
What is the measurement of how much heat energy is required for a substance to melt?
heat of fusion
The energy required to melt one gram of a substance is known as what?
heat of fusion
What does the latent heat of fusion?
The energy required to melt a substance
What is SI unit of latent heat of fusion?
The latent heat of fusion is defined as the heat energy required to convert a kg of a substance of liquid into solid of the same substance without a change of temperature. Q = mL where Q = Heat Energy in joules, m=mass of substance, L= Latent heat of fusion Taking units, [J] = [kg] [L] [L] = [J]/[kg] so units of latent heat of fusion are joules.kg-1
Which heat changes the state of a substance without changing its temperature?
both the heat of fusion and the heat of vaporization
How does the presence of hydrogen bonds affect the heat of fusion of a substance?
guyhbn
What does the latent heat of fusion measured?
The energy required to melt a substance
What The heat of fusion of a substance is the energy measured during a?
phase change
What is a similarity between heat fusion and heat solidification?
When changing from a solid to a liquid, melting, the heat absorbed is called the heat of fusion. When the reverse takes place, freezing, it is called the heat of solidification. For a single substance they are the same.
