For example, it takes some energy (heat energy) to convert ice, at zero degrees, to water, also at zero degrees. While heat energy is added, the ice melts, but its temperature doesn't increase. The heat is used up, in a sort of potential energy - i.e., to break bonds between adjacent water molecules. The amount of heat required is specified per unit of mass. As an example, the latent heat of fusion of water is 334 kJ/kg, that is, it requires 334 kilojoule of energy to melt one kilogram of ice. "Melting" is the same as fusion in this context. "Vaporisation" is the same basic idea, but to convert a liquid to a gas - for example, liquid water to water vapor.

What does latent heat or fusion mean?
Latent heat of fusion is the energy required to change a substance from solid to liquid at its melting point, without changing its temperature. It represents the energy needed for the molecules to break free from their fixed positions in a solid structure.
Does steam has highest latent heat than boiling water?
Boiling water has a lower latent heat than steam. Steam is the transition from liquid to gas for boiling water. If by boiling water you mean liquid water at the temperature of 100 degrees Celsius then yes, steam has a higher latent heat.
What does it mean to have a higher specific heat?
Having a higher specific heat means that a substance requires more energy to change its temperature compared to a substance with a lower specific heat. This property can help regulate temperature changes, making substances with higher specific heat more resistant to rapid temperature fluctuations.
Does a high or low specific heat mean the substance heats up so fast?
A low specific heat means the substance heats up faster, as it requires less energy to raise its temperature. Conversely, a substance with a high specific heat requires more energy to raise its temperature, so it heats up more slowly.
Why is the temperature expected to remain constant during the thermal arrest?
I think you must mean the 'latent heat of fusion' experiment where a change of state in the cooling curve of a hot liquid like naptha or Octadecanol. the liquid cools as expected until the liquid starts to solidify. The temperature drop is arrested as the crystallisation process emits latent heat. Having solidified it then cools as expected.
What does L mean in the equation Heat equals mL?
L can either mean the latent heat of vaporization or condensation. The latent heat of vaporization is the energy required to completely turn 1 kilogram of a liquid into a gas at its boiling point. The latent heat of condensation is the energy required to completely turn 1 kilogram of a solid into a liquid at its melting point.
What does latent heat or fusion mean?
Latent heat of fusion is the energy required to change a substance from solid to liquid at its melting point, without changing its temperature. It represents the energy needed for the molecules to break free from their fixed positions in a solid structure.
Q - What is the difference between latent heat of fusion and latent heat of solidfication?
They are the same thing. Fusion and solidification both mean the changing of a liquid to a solid.
Does steam has highest latent heat than boiling water?
Boiling water has a lower latent heat than steam. Steam is the transition from liquid to gas for boiling water. If by boiling water you mean liquid water at the temperature of 100 degrees Celsius then yes, steam has a higher latent heat.
Is it true that it takes a lot of heat to melt a substance with a low melting point?
See the expert answer above for a specific answer to the question. However, if you mean 'what is a low melting point' then it means that the temperature at which the substance becomes a liquid is reasonably easy to get to, so you have to provide less heat to get to the melting point than you would if it were high.
Which occours when a liquid becomes a gas?
What do you mean? It's evaporation... The liquid absorbs latent heat from the surrounding...
What late heat mean in HVAC?
All pure substances in nature are able to change their state. Solids can become liquids (ice to water) and liquids can become gases (water to vapor) but changes such as these require the addition or removal of heat. The heat that causes these changes is called latent heat. Latent heat however, does not affect the temperature of a substance - for example, water remains at 100°C while boiling. The heat added to keep the water boiling is latent heat. Heat that causes a change of state with no change in temperature is called latent heat. Appreciating this difference is fundamental to understanding why refrigerant is used in cooling systems. It also explains why the terms 'total capacity' (sensible & latent heat) and 'sensible capacity' are used to define a unit's cooling capacity. During the cooling cycling, condensation forms within the unit due to the removal of latent heat from the air. Sensible capacity is the capacity required to lower the temperature and latent capacity is the capacity to remove the moisture from the air.
Which biological process uses the latent heat vaporization of water?
i think d...................... what you mean
What does 2.5 ton ac mean?
Cooling capacity of 30,000 btu per hour. That is the nominal total of both sensible and latent heat.
Explain how the specific heat of a substance is determined?
specific heat is the amount of heat to be absorbed required to raise a substance 1 degree celsius. And by heat being absorbed, i mean energy, because specific heat is measured in joules
What chemical bond possess low latent heat of fusion?
Latent heat of fusion (or enthalpy of fusion) is a characteristic of a substance, rather than a chemical bond. If you mean enthalpy of reaction then the lowest absolute values are for the bonds in H2, F2, and Cl2 as gases, which are zero. One low (and negative) value is for cuprous sulphate. Please see the link.
What does quiescent mean in medical terms?
rest, latent.
