To determine the specific latent heat of ice in J/kg without a calorimeter, one must measure the vapor pressures of both the solid and liquid phases and calculate the enthalpies of vaporization at 0°C. The difference between these enthalpies will yield the enthalpy of fusion. While specific heat and latent heat are distinct concepts, the term "specific latent heat" is not commonly used but is not incorrect. Essential equipment includes a mass scale, heater, thermometer, and stopwatch. Accurate measurements and calculations are crucial for determining the latent heat effectively.
