The heat of fusion is used to first convert the volume of liquid to its solid form, then the heat of vaporization is used to convert the solid to vapor. By summing the two energy values, you can calculate the total energy required to vaporize the liquid volume.

The heat of fusion is the amount of heat energy required to change a substance from a solid to a liquid at its melting point. It is typically measured in joules or calories per gram. The specific heat of fusion for water is 334 J/g.
The energy required to melt a solid into a liquid is called the heat of fusion or enthalpy of fusion. It represents the amount of energy needed to overcome the intermolecular forces holding the solid together and transition it into a liquid state.
To determine the specific heat capacity of a liquid, you can use a calorimeter. By measuring the initial and final temperatures of the liquid when it absorbs a known quantity of heat, you can calculate the specific heat capacity using the formula Q = mcΔT, where Q is the heat absorbed, m is the mass of the liquid, c is the specific heat capacity, and ΔT is the change in temperature.

To calculate the heat required to convert ice to liquid at a temperature of 14.7°C, we first need to heat the ice from -12.1°C to 0°C, using the specific heat capacity of ice. Then we calculate the heat required to melt the ice at 0°C to water at 0°C, using the heat of fusion of ice. Finally, we calculate the heat required to heat the water from 0°C to 14.7°C, using the specific heat capacity of water. By performing these calculations, we can determine if the available heat of 4390 J is sufficient.

To calculate the time it would take to heat 200 gallons of water by 180 degrees using a 600 Btu water heater, you would first determine the total heat required: Calculate the heat energy required: Q = mcΔT, where Q is the heat energy, m is the mass of water, c is the specific heat of water, and ΔT is the temperature change. Then, calculate the time required to heat the water using the formula: Time = Q / power of the heater. These calculations will give you an estimate of the time needed to heat the water based on the specific heat capacity of water and the power of the heater.
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.
You could calculate the molar heat of sublimation as long as you know by placing a known amount of a known quantity in a calorimeter and measuring the change in temperature during sublimation. Then use the equation E=mc(change in T) where E is energy in joules, m is mass, c is heat capacity, and T is temperature.
