The transformation of a solid into a liquid requires each atom to become more excited and vibrate, moving away from its neighbouring atoms, so as to allow flow. This increased "excitement" requires significant amounts of energy, and thus, latent heat is required to give that extra boost of energy so as to allow the conversion.
What else can I help you with?
Two HVACR technicians are discussing the change of states in matter. Technician A says that the latent heat of fusion is the amount of heat that must be added to matter to convert it from a liquid to?
Technician A is incorrect. The latent heat of fusion is the amount of heat required to convert a solid into a liquid at its melting point. To convert a liquid to a gas, you would need to add the latent heat of vaporization.
What is latent of fusion?
The energy required to go from a solid to a liquid-Apex
What is latent heat of sublimation?
When a substance is below the triple point, the equilibrium will be between solid and vapor rather than solid/liquid or liquid/vapor. Sublimation is the direct change from solid to vapor without any intermediate phase change. The latent heat of sublimation is the energy required to change a given quantity of solid into the vapor at equilibrium. It is analogous to (but not the same as) latent heat of melting (energy required to melt the solid to liquid) and latent heat of vaporization (energy required to change a liquid into a gas).
What is Latent heat of fusion dependent?
The latent heat of fusion is dependent on the substance undergoing the phase change from solid to liquid. It is influenced by the specific properties of the material, such as its molecular structure and intermolecular forces. The amount of energy required to overcome these forces and convert the substance from a solid to a liquid state determines the value of the latent heat of fusion.
What does the latent heat of fusion represent?
The energy required to melt a substance. (Apex)
What is the energy required to go from a solid to a liquid called?
The latent heat of fusion
What is the latent heat of sublimation?
No. Latent heat of vaporization is defined as the energy required to VAPORIZE 1 kilogram of a liquid completely at its boiling point. Latent heat of sublimation is the energy required to SUBLIME 1 kilogram of a solid completely into a gas at constant temperature. They're different. Note that the temperatures should be constant during the processes.
What does latent heat of fusion represents?
The amount of heat energy required to solid substance solid into a liquid state without any changes in temperature ______________________ Apex: The amount of energy required to turn a mole of a solid into a liquid
What is specific latent of fusion?
It is the amount of energy required to change 1kg of solid into a liquid with no temperature change.
Latent heat is the energy required for 1 kg of a substance to change?
Latent heat is the energy required for 1 kg of a substance to change ___________. phase
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
What is the energy required to go from solid to a liquid called?
The latent heat of fusion
