Stoichiometry is used to calculate the energy released when a mass of liquid freezes by applying the concept of heat transfer during phase changes. The heat released can be determined using the formula ( Q = m \cdot \Delta H_f ), where ( Q ) is the heat energy, ( m ) is the mass of the liquid, and ( \Delta H_f ) is the enthalpy of fusion (the amount of energy released when the substance freezes). By knowing the mass of the liquid and its enthalpy of fusion, one can calculate the total energy released during the freezing process.
347 J/g.K or 83 cal are released.
i wanna know this answer too.
No, freezing is exothermic as the water loses energy to its surroundings as it freezes.
Endothermic reactions absorb heat energy from the surroundings. To calculate the energy change in an endothermic reaction, you subtract the initial energy of the reactants from the final energy of the products. The resulting positive value indicates that the reaction absorbed energy.
Water releases energy to its surroundings when it cools down and freezes into ice, or when it condenses from water vapor into liquid water. This energy release is known as heat of fusion or heat of condensation, respectively.
Grams Liquid x mol/g x Hfusion
The heat of fusion is the amount of energy needed to change a substance from a liquid to a solid. To calculate the energy released when a mass of liquid freezes, you would use the equation Q = m * Hf, where Q is the energy released, m is the mass of the substance, and Hf is the heat of fusion.
Stoichiometry can be used to determine the amount of heat energy released during the freezing of a liquid by relating the quantity of the substance that freezes to the heat of fusion of the substance. This involves multiplying the mass of the liquid that freezes by the heat of fusion value to calculate the total energy released. This calculation helps in understanding the energy changes that occur during phase transitions like freezing.
Stoichiometry can be used to calculate the energy released when a mass of liquid freezes by accounting for the heat of fusion of the substance. By calculating the amount of heat energy required to freeze the liquid based on its specific heat capacity and mass, you can determine the energy released during the phase change. This can be expressed through the equation Q = m * h_f, where Q is the energy released, m is the mass of the substance, and h_f is the heat of fusion constant.
Stoichiometry can be used to calculate the energy released during the freezing of a liquid by calculating the moles of the liquid that freeze and then using the enthalpy of fusion of the substance (given in kJ/mol) to determine the total energy released during the process. The energy released can be found by multiplying the moles of liquid that freeze by the enthalpy of fusion value.
To calculate the energy released when 1.56 kg of ethanol freezes, first convert the mass of ethanol to moles using its molar mass. Then, use the heat of fusion of ethanol to determine the energy released using the formula: Energy released = moles of ethanol x heat of fusion.
When a substance freezes, it releases energy as it changes from a higher-energy state (liquid) to a lower-energy state (solid). The energy is released as heat into the surroundings.

Grams liquid × mol/g × Hfusion
When liquid water freezes into ice, energy is released. This is because the process of freezing involves the molecules in water slowing down and arranging themselves into a more ordered solid structure, which releases heat energy.
To calculate the energy released when 150 grams of water freezes, you need to know the heat of fusion of water, which is 334 J/g. You can then multiply this value by the mass of water to find the energy released. In this case, it would be 150 grams * 334 J/g = 50,100 J or 50.1 kJ.
347 J/g.K or 83 cal are released.
