How much energy is needed to melt 25.4grams of l2?
To calculate the energy needed to melt 25.4 grams of I2 (iodine), you can use the formula: energy = mass x heat of fusion. The heat of fusion for iodine is 15.52 kJ/mol. First, find the molar mass of I2 (253.8 g/mol) and then convert the mass to moles. Finally, multiply the moles by the heat of fusion to get the energy needed.
Why does it take more heat to boil a substance than to melt it?
The energy required to completely separate the molecules in a liquid and convert them to a gas (boiling), is greater than the energy needed to completely separate the molecules in a solid and convert them to a liquid (melting).
Where does the energy needed to melt the iron come from?
The energy needed to melt iron typically comes from heating the iron to its melting point, which requires input of heat energy. This heat energy can be created by burning fuels, using electric resistance, or other heat sources that can raise the temperature of the iron to the point where it transitions from a solid to a liquid state.
How much energy is required to melt 56g?
The energy required to melt a substance can be calculated using the formula: Energy = mass x heat of fusion. For water, the heat of fusion is 334 J/g. Therefore, the energy required to melt 56g of water would be 56g x 334 J/g = 18,704 J.
How is the H fusion used to calculate the energy needed to melt a mass of solid?
The heat fusion (H fusion) is the amount of energy required to change a substance from solid to liquid at its melting point. To calculate the energy needed to melt a mass of solid, you multiply the mass of the substance by its heat of fusion. The formula used is ( Q = m \cdot H_f ), where ( Q ) is the energy required, ( m ) is the mass, and ( H_f ) is the heat of fusion. This calculation provides the total energy needed to completely melt the solid into a liquid at its melting temperature.

How much enjergy is needed to melt 4.24 grams of Pd?
The energy required to melt a substance is its heat of fusion. For Palladium (Pd), the heat of fusion is 16.74 kJ/mol. To calculate the energy needed to melt 4.24 grams of Pd, first convert to moles by dividing by the molar mass of Pd (106.42 g/mol), then multiply by the heat of fusion. This yields approximately 3.34 kJ of energy needed to melt 4.24 grams of Pd.
How much energy is needed to melt 4.24 grams of Pd?
The energy required to melt a substance can be calculated using the heat of fusion value for that substance. The heat of fusion for palladium (Pd) is 16.74 kJ/mol. To convert grams to moles, divide the given mass by the molar mass of Pd (106.42 g/mol), then multiply by the heat of fusion value to find the energy needed to melt 4.24 grams of Pd.
How much energy in kJ is needed to melt 183.3 g of water at 0 C?
The energy needed to melt ice is given by the formula Q = m * L_f, where Q is the energy required, m is the mass of water, and L_f is the heat of fusion of water (334 J/g). Converting 334 J/g to kJ/g gives 0.334 kJ/g. Multiplying these together, we find that 183.3 g of water will require 61.21 kJ of energy to melt at 0°C.
How much energy is needed to melt 2kg of gold?
It takes approximately 64,000 Joules of energy to melt 1kg of gold. Therefore, to melt 2kg of gold, you would need around 128,000 Joules of energy.
Why energy is needed to melt ice and how this is explained by the structures of ice and water?
Because the ice structure is made up of frozen water molecules, which are blown by fairies creating heat which makes the ice melt like butter in a dragons mouth.
How much energy is required to melt 1.5 kg of gold?
The heat of fusion for gold is 64.4 kJ/mol. To convert this to energy required to melt 1.5 kg of gold, we need to calculate the number of moles in 1.5 kg of gold (1.5 kg of gold is approximately 0.047 moles). Then, the energy required would be approximately 3.03 kJ.
