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?
It is a known fact : Molar heat of sublimation = molar heat of fusion + molar heat of vaporization so, molar heat of vaporization = molar heat of sublimation - molar heat of fusion Mv = 62.3 kJ/mol - 15.3 kJ/mol Mv = 47 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).
How much heat in kJ is required to melt 54.0 g of ice at 0 and degC into water at 0 and degC if and DeltaHfus for water 6.01 kJmol?
The first step is to convert the mass of ice to moles using the molar mass of water (18.015 g/mol). Then, use the molar enthalpy of fusion to determine the heat required to melt the ice. Finally, multiply the molar enthalpy of fusion by the number of moles of water to get the total heat required in kJ.
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?
Molar heat capacity of liquid water = 75.3538 Molar heat capacity = molar mass x specific heat

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 do you calculate the molar heat of fusion?
Use Einstein's Theory of Special Relativity
How are the heat of fusion of ice and heat of fusion of water similar?
due to the anomalous behaviour of water.....
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?
Molar heat capacity of liquid water = 75.3538 Molar heat capacity = molar mass x specific heat
A sentence for heat of fusion?
Because of the heat of fusion the ice is now water
What is greater water heat of fusion or its heat of vaporization?
The heat of vaporization of water is greater than its heat of fusion. Specifically, the heat of vaporization is approximately 2260 joules per gram, while the heat of fusion is about 334 joules per gram. This means that it requires significantly more energy to convert water from a liquid to a gas than to change it from solid to liquid.
What is the negative heat for water as a ice?
The heat of fusion refers to the energy required to change a substance from a solid to a liquid at its melting point. For water to change from ice to liquid water, heat needs to be added, making the heat of fusion a positive value.
