To find the enthalpy change when 1.0 g of water is frozen at 0°C, we can follow these steps: ### Step 1: Understand the given data We are provided with the enthalpy of fusion (ΔH_fus) for water, which is 6.02 kJ/mol. This value indicates the amount of energy required to convert 1 mole of ice into water at 0°C. ### Step 2: Convert the enthalpy of fusion to joules Since 1 kJ = 1000 J, we convert the enthalpy of fusion: \[ ...
