What is meant by latent heat of fusion of ice is 80 cal GM?
The latent heat of fusion for ice is 80 calories per gram (see calorie). This amount of heat is absorbed by each gram of ice in melting or is given up by each gram of water in freezing. The latent heat of vaporization of steam is 540 calories per gram, absorbed during vaporization or given up during condensation.

1 Answer. The value of latent heat of fusion = 160 cal.
What is meant by specific latent of fusion of ice?
The specific latent heat of fusion of ice is the amount of heat required to change 1 kg of ice to water without a change in temperature.
What is the value of latent heat of fusion of water?
It is also a latent heat and is sometimes called the latent heat of fusion. It has only one value for water, because water freezes at one value (0 °C), and it is 79.71 cal/g or the rounded number 80 cal/g. The high heat of fusion of water is used in frost control.
What does it mean by saying latent heat of fusion of ice is 80 kcal kg?
A given amount of ice always requires the same amount of heat to melt it; 1 kg of ice needs 80 kcal to change it into water, thus the latent heat of fusion of ice is 80 kcal/kg (Fig 4).
What is latent heat of fusion state its unit?
The specific latent heat of fusion of ice is defined as the quantity of heat required to convert the unit mass of ice into liquid at 0°C (without change in temperature). The SI unit of specific latent heat is J/Kg or JKg-1.
What is meant by specific latent is heat of fusion of ice 80 kcal kg?
Solution : When 1g o ice at a pressure of one atmosphere and at a temperature `0^(@)C` is converted into 1 g of water, heat absorbed by the ice is 80 cal. Loading Books. Answer. Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams. ×
What are the value of latent heat of fusion of ice and latent heat of vaporization for with water?
The value of latent heat of fusion of ice and latent heat of vapourisation of water are 80 cal/g and 540 cal/g respectively.
What is meant by saying that the latent heat of ice is 3.34 105 J kg?
What is meant by saying that the latent heat of fusion of ice is 3.34 × 105 J/kg? The latent heat of fusion of ice is 3.34 × 105 J/Kg means that 3.34 × 105 J of heat is required to change 1 kg of ice into the water at its melting point at the same temperature.
What do you mean by specific latent heat of ice is 80 cal GM?
What is the value of latent heat of vaporization of ice?
Only one-quarter of the heat produced is absorbed by the ice and all energy of ice gets converted into heat during its fall. The value of h is [Latent heat of ice is 3.4×105J/kg and g=10N/kg]: Physics.
What do you mean by latent heat of fusion of ice is 80 calories per gram?
Hint: The latent heat of fusion of ice is 80 calories per gram. This means that 80 calories of heat absorbed by one gram of ice is melting. This is the same amount of heat that was given up when the water froze.
How do you find the heat of fusion of ice?
Key Takeaways: Heat of Fusion for Melting Ice
- Heat of fusion is the amount of energy in the form of heat needed to change the state of matter from a solid to a liquid (melting.)
- The formula to calculate heat of fusion is: q = m·ΔHf
How do you calculate the latent heat of fusion of a substance?
The latent heat of fusion equation is the heat per mass of substance undergoing a phase change Lf=q/m L f = q / m where q is the flow of energy from one body to another, which is equal to the mass m of the substance that is losing or gaining heat multiplied by the change in temperature ΔT Δ T and the specific heat …
What is meant by statement latent heat of fusion of ice is 334 J per gram?
Solution. The latent heat of fusion of ice is 3.34 × 105 J/Kg means that 3.34 × 105J of heat is required to change 1 kg of ice into water at its melting point at the same temperature. Concept: Change of State of Matter.
What is the latent heat of ice in kJ kg?
(1) 333.55 J/g (heat of fusion of ice) = 333.55 kJ/kg = 333.55 kJ for 1 kg of ice to melt, plus.
What is latent heat of fusion of water?
What is the latent heat of fusion and vaporization?
The latent heat associated with melting a solid or freezing a liquid is called the heat of fusion; that associated with vaporizing a liquid or a solid or condensing a vapour is called the heat of vaporization.
How specific latent heat of fusion of ice can be determined by the method of mixture?
In this experiment the heat of fusion of ice will be determined by using the method of mixtures (Quantity of heat lost = Quantity of heat gained). where Q is the amount of heat absorbed by the solid, M is the mass of the solid and Lf is the latent heat of fusion measured in cal/g (to fuse means to melt).
How will you determine the latent heat of ice?
latent heat of fusion of ice (LHice),the energy needed (per gram) to melt ice. The needed energy will come from a cup of warm water. The amount of water and its temperature will be measured before adding some ice and then again after the ice has been melted. These data will be used in an energy
What is the equation for latent heat of fusion?
The formula for Latent heat of fusion: If m kg of the solid changes into the liquid at a constant temperature which is its melting point. Then the heat absorbed by it means the latent heat of fusion formula will be, Q = (m times L_f) Also, if the temperature of some object varies from the lower temperature (t_1) to higher temperature (t_2
What is the latent heat of fission?
What is Latent Heat? Latent heat is defined as heat energy that is absorbed or released during the transition phase of a substance. It can be either the transition of gas to a liquid or a liquid to a solid. The latent heat that is related to the total heat energy of a thermodynamic system is known as enthalpy.
What is the cause of latent heat?
Latent heat is the heat the results from an increase or decrease in the amount of moisture held by the air. Specifically, it’s the amount of energy needed to cause a phase change (for our purposes, liquid-to-gas or gas-to-liquid) without changing the actual temperature of a substance.
