∙ 7y agoThe amount of energy used to melt a solid is known as the enthalpy of fusion, and this value is on a per gram or per kg basis (or on a mole basis). At any rate, it is related to the mass. The larger the mass, the more energy is needed. So, in order to calculate energy needed to melt a solid, one needs to know the heat of fusion AND the MASS of the object.

(Explanation): the other answers had Hf, Hvap, Hreaction and Hfusion as options. Remember that melting is associated with fusion, so the answer with Hfusion is the correct answer.

Is energy absorbed or released when a solid melts a liquid vaporizes a gas condenses and a liquid melts?
Melting and boiling (vaporization) absorb energy, freezing and condensing release energy.
The energy absorbed by one gram of ice as it melts as known as the .for water?
Heat of Fusion
When ice melts latent heat is absorbed from the environment sufficient to essentially?
Breaking the hydrogen bonds that maintain water
When ice melts it gains energy and is call this type of change?
When ice melts it is called a physical endothermic change.
What is basic difference between melting and fusion?
Melting point is the temperature at which something melts. Like ice has a melting point of 0 Celsius. The heat of fusion is the heat energy that is absorbed (or released) when a substance melts (or freezes) an is measured in energy units, either calories or joules. Ex. One gram of ice must absorb 80 calories of heat energy to change into liquid water.
How is stoichiometry used to calculate energy absorbed when mass of solid melts?
Grams solid × mol/g × Hfusion
When ice melts to form water energy is what?
Absorbed.
When a substance changes from solid to a liquid?
It melts. Energy is absorbed.
To calculate the amount of heat absorbed as a substance melts what information is not needed?
the density of the sample.
What is known as the energy absorbed by one gram of ice as it melts?
heat of fusion
Is energy absorbed or released when a solid melts a liquid vaporizes a gas condenses and a liquid melts?
Melting and boiling (vaporization) absorb energy, freezing and condensing release energy.
Why is energy absorbed when ice melts?
When an ice cube gains energy, it is the same as gaining heat. So if an ice cube is getting warmer, it melts.
The energy absorbed by one gram of ice as it melts as known as the .for water?
Heat of Fusion
The change in which ice absorbs energy and melts is a?
Endothermic reactions are those in which energy is absorbed during the reaction. Exothermic reactions are those in which heat is evolved during the reactions.When ice melts its absorbs energy in the form of heat so why it melts,
Describe the role of energy when ice melts and when vapor condences to form liquid water?
When water molecules melt, energy is absorbed. When water molecules evaporate, energy is also absorbed. When water molecules condense energy is released. When water molecules freeze energy is also released.
How the energy of matter changes when it melts.?
When a solid melts, it is due to an increase in thermal energy to the temperature at which it melts.
When temperature does not increase and there is a constant supply of energy where does the energy go?
One possibility is that the temperature is absorbed by a change of phase - for example, when ice melts. This is an increase in potential energy. Of course, it is also possible for energy to drain off (the object cools down while energy is being supplied).
