It is the amount of energy required to change the state of 1kg of a substance with no change in temperature.

What unit is specific latent heat measured in?
The unit for specific latent heat is J Kg-1(Joules per Kilogram)
What two factors does a materials specific heat latent depend on?
A material's specific heat and latent heat depend on the type of substance and its phase (solid, liquid, or gas). Specific heat is the amount of heat needed to raise the temperature of 1 kg of the substance by 1°C, while latent heat is the amount of heat absorbed or released during a phase change at a constant temperature.
What is the relationship between specific heat and latent heat in the context of thermal energy transfer?
Specific heat and latent heat are both properties of a substance that determine how it absorbs or releases thermal energy. Specific heat refers to the amount of heat required to raise the temperature of a substance by a certain amount, while latent heat is the amount of heat needed to change the state of a substance without a change in temperature. In thermal energy transfer, specific heat affects the temperature change of a substance, while latent heat is involved in phase changes such as melting or boiling.
What are the factors that affect specific latent heat of fusion of a substance?
The amount of energy needed to change the "state of matter" is termed as "latent heat". This is not same for vapourisation (liquid to vapour) or for fusion (solid to liquid). For example, latent of fusion is 79.7 cal whereas latent heat for vapourisation is 541 calories. The latent depends on how closely the atoms and molecules in the matter are closely packed.
What is the difference between specific heat and latent heat, and how do they affect the heat transfer process?
Specific heat refers to the amount of heat required to raise the temperature of a substance by one degree Celsius, while latent heat is the heat absorbed or released during a phase change without a change in temperature. Specific heat affects the temperature change of a substance, while latent heat affects the phase change process. Both specific heat and latent heat play a role in heat transfer processes by determining how much heat is needed to change the temperature or phase of a substance.
Is specific latent heat of ice is same for water or not?
The specific latent heat of ice and water is not the same. The specific latent heat of fusion for ice (the heat required to convert ice to water at 0°C) is approximately 334 kJ/kg, while the specific latent heat of vaporization for water (the heat required to convert water to vapor at 100°C) is significantly higher, around 2260 kJ/kg. Thus, the energy required for phase changes differs between ice and water.
Can you measure Latent heat with a thermometer?
No, latent heat cannot be measured directly with a thermometer. Latent heat is the energy absorbed or released during a phase change (e.g. melting, boiling) without a change in temperature. The amount of latent heat can be calculated using specific equations and constants for each substance.
What two things does the specific latent heat of a material depend on?
The specific latent heat of a material depends on the substance being considered and the phase change involved, such as condensation or freezing.
What is the specific latent heat of fusion for a substance that takes 550 kJ to melt 14 kg at 262 K?
The specific latent heat of fusion can be calculated by dividing the energy required to melt the substance by the mass of the substance. In this case, the specific latent heat of fusion would be (550 kJ) / (14 kg) = 39.29 kJ/kg.
What is the difference in specefic heat and latent heat?
Specific heat is the heat energy in joules required to rise the temperature of one kg of substance through one kelvin without a change in its state. But latent heat is the heat required to change the state of one kg of substance without change in temperature.
Was Joseph Black famous?
yes he was known for Latent heat, specific heat, and the discovery of carbon dioxide
What is the symbol for latent heat?
The symbol for latent heat is ( L ).
