It varies by the actual Alloy, but around 340°C it will be affected.

How does specific latent heat of water vary with temperature?
Latent heat of water is the heat required to change its state at a particular temperature BECAUSE of the pressure at which the water is at at the point of fusion or evaporation.The latent heat is not affected by temperature (in fact there is no temperature change during absorption of latent heat) it is affected by the pressure acting on a substance. As the pressure increases, the latent heat (of evaporation) decreases, consequently with the change in pressure there is also a different temperature at which the evaporation takes effect, higher pressure, higher temperature at the evaporation point.
Why is heat of fusion called the latent heat of fusion?
It is called latent because heat is supplied without any increase in temperature.
What is the difference between latent heat of fusion and latent heat of vapourization?
the heat which is absorbed by a substance for changing solid into liquid state by keeping temperature constant is called latent heat of fusion while the heat which is evolved during phase change of liquid to vapour state at constant temperature is called latent heat of vapourization
Latent heat energy levels?
The latent heat energy levels refers to the heat absorbed during a change phase at a constant pressure and temperature.
Would the computed Latent heat of fusion be affected if the ice in the inner cup is not totally melted when the final temperature is determined?
yes. because the temperature will change. thus, increasing ur error.
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
Difference between latent heat from sensible heat?
Two forms of heat are relevant in air conditioning:1. Sensible Heat2. Latent HeatSensible heatWhen an object is heated, its temperature rises as heat is added. The increase in heat is called sensible heat. Similarly, when heat is removed from an object and its temperature falls, the heat removed is also called sensible heat. Heat that causes a change in temperature in an object is called sensible heat.Latent heatAll 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.
Why is latent heat called hidden heat?
The latent heat of fusion refers to the heat of fusion in reactions that involve a solid that forms a liquid, or vice versa. The latent heat of vaporization is the latent heat involving a liquid that forms a gas or vice versa.Latent means hidden or unseen. In this context, the 'latent' heat is the heat that is not detectable as a temperature change in the substance. Rather than adding kinetic energy (which is detectable as a temperature change) some heat is required to break the bonds of the solid structure.
Why does the temperature stops rising during melting and boiling point?
Because the latent heat of fusion and latent heat of vaporization are very high
What is the specific latent heat of fusion of mercury?
The specific heat temperature of mercury is 14 degrees Celsius. Comparably, the specific temperature of water is 417.9 degrees and air is 101 degrees.
What type of energy is absorbed or released when a substance changes phase?
pChanges in bonding arrangements between atoms and molecules result in absorption or release of heat (called latent heat). For example when water freezes, some heat is extracted to the environment, and the temperature does not fall until all is frozen. After that further removal of heat causes the temperature to fall below freezing point.
What is the difference between latent heat and heat?
Usually as we give heat to a system then temperature of the system would rise. But at the boiling point though we give enormous amount of heat the temperature would remain the same and so the heat given is said to be latent and it is used to change water from liquid state to gaseous state. Hence the name latent heat
