Approximately how many Joules of heat are needed to completely change 10.0 grams of ice to water at the melting point temperature?

To completely change 10.0 grams of ice to water at the melting point temperature, we need to calculate the heat required for the phase change from solid to liquid and the heat needed to raise the temperature of the resulting water to the melting point temperature. The heat of fusion for water is 334 J/g, so the heat needed for the phase change is 10.0 g * 334 J/g = 3340 J. The heat needed to raise the temperature of the resulting water to the melting point temperature is calculated using the specific heat capacity of water, which is 4.18 J/g°C. The temperature change is from 0°C to 0°C, so no additional heat is needed for this step. Therefore, the total heat required is 3340 J.
