How much energy does it take to melt ice?
A total of 334 J of energy are required to melt 1 g of ice at 0°C, which is called the latent heat of melting. At 0°C, liquid water has 334 J g’1 more energy than ice at the same temperature. This energy is released when the liquid water subsequently freezes, and it is called the latent heat of fusion.
How much energy does it take to melt 5g of ice?
Answer: The amount of heat required to melt 25 grams of ice is 8,350 Joules or 2,000 calories. Note: Heat of fusion should be a positive value.
How much energy is needed to melt 5g of ice?
Answer: The needed energy to melt of ice is 1670 J. Hence, The needed energy to melt of ice is 1670 J.
What is the heat required to melt 10 grams of ice?
So,to convert 10g of ice at 0∘C to same amount of water at the same temperature, heat energy required would be 80…10=800 calories. So,to convert water at 100∘C to steam at 100∘C heat energy required will be 537…10=5370 calories.

How do you calculate latent heat of fusion?
Find the latent heat of fusion, Lf, according to Lf = q ÷ m by dividing the heat, q, absorbed by the ice, as determined in step 3, by the mass of ice, m, determined in step 4. In this case, Lf = q / m = 2293 J ÷ 7.0 g = 328 J/g. Compare your experimental result to the accepted value of 333.5 J/g.
What is latent heat and its types?
Latent heat is energy released or absorbed, by a body or a thermodynamic system, during a constant-temperature process. Two common forms of latent heat are latent heat of fusion (melting) and latent heat of vaporization (boiling).
What is Latent Heat Class 9?
The heat energy which has to be supplied to change the state of a substance is called its latent heat. Latent heat does not raise (or increase) the temperature. But latent heat has always to be supplied to change the state of a substance .
What is the difference between latent heat and specific heat capacity?
Hi Shrawani Latent heat capacity is the heat required by a substance without the change in temperature. Specific heat capacity is the heat required by a substance of unit mass to change the temperature by 1 degree C.
What is latent heat of fusion explain with example?
For example, the amount of energy absorbed by ice to become water is equal to the amount of energy liberated by water to become ice. The latent heat of fusion of a substance also accounts for the energy required to accommodate any increase in the volume of the substance post the change of its physical state.
33600 J/K.
What is the heat of fusion for water?
The heat of fusion for water at 0 °C is approximately 334 joules (79.7 calories) per gram, and the heat of vaporization at 100 °C is about 2,230 joules (533 calories) per gram.
What substance has the highest latent heat of fusion?
Ice
What is latent heat of fusion used for?
Fusion. The latent heat of fusion is the heat required for an object to go from the solid state to the liquid state, or vice versa. Since its value is generally much higher than specific heat, it allows you to keep a beverage cold for much longer by adding ice than simply having a cold liquid to begin with.
Why is it called latent heat of fusion?
Latent heat of fusion is the heat which is required to make 1kg of solid into liquid. This heat remains hidden until solid is completely transferred into liquid. It is called latent heat because latent means hidden.
What is Latent Heat Short answer?
Latent heat is defined as the heat or energy that is absorbed or released during a phase change of a substance. It could either be from a gas to a liquid or liquid to solid and vice versa. Latent heat is related to a heat property called enthalpy.
