The molar heats of sublimation and fusion of iodine are 62.3kjmol and 15.3kjmol respectively calculate the molar heat of vaporization of liquid iodide?
The molar heat of vaporization of iodine can be calculated using Hess's Law. The molar heat of sublimation is the sum of the molar heat of fusion and the molar heat of vaporization, so: 62.3 kJ/mol = 15.3 kJ/mol + x kJ/mol. Solving for x, the molar heat of vaporization is 47.0 kJ/mol.
The molar heat of fusion for water is 6.008 kJmol What quantity of heat energy is released when 253 g of liquid water freezes?
To calculate the heat released when 253 g of water freezes, first convert the mass to moles using the molar mass of water (18.015 g/mol). Then, use the molar heat of fusion to determine the total heat released. Therefore, 253 g of water is 14.05 moles (253 g / 18.015 g/mol) and the heat released is 84.5 kJ (6.008 kJ/mol * 14.05 mol).
What is the molar heat of fusion of ethanol?
The molar heat of fusion of ethanol is approximately 5.02 kJ/mol. This is the amount of energy required to convert one mole of solid ethanol into liquid ethanol at its melting point of -114.1°C.
Molar heat capacity of water?
The molar heat capacity of water is 75.3 J/mol K at constant pressure. This means that it takes 75.3 joules of energy to raise the temperature of one mole of water by 1 Kelvin.
A sentence for heat of fusion?
The heat of fusion is the amount of energy needed to change a substance from a solid to a liquid at its melting point.
The amount of heat necessary to change 1 kg of a solid into a liquid at the same temperature is called the?

What is the relation of the molar heat of fusion to the molar heat of vaporization?
Molar heat of fusion: the heat (enthalpy, energy) needed to transform a solid in liquid (expressed in kJ/mol). Molar heat of vaporization: the heat (enthalpy, energy) needed to transform a liquid in gas (expressed in kJ/mol).
How much heat is requires to convert 0.3 kilogram of ice at 0 C to water at the same temperature?
The molar heat of fusion of water in J / g is 334. To find the heat required to convert 0.3 kg, use the equation: heat of fusion * mass = heat required. It would require 100.2 kJ.
How do you calculate the molar heat of fusion?
Use Einstein's Theory of Special Relativity
