Final answer:
The mass of water that would release 16700J of energy when freezing is approximately 0.0499 kg
Step-by-step explanation:
The mass of water that would release 16700J of energy when freezing can be calculated using the specific heat capacity and heat of fusion of water. It takes 334 kJ/kg of energy to freeze water, so the mass of water can be calculated as:
M = Q / (c * ΔT)
where M is the mass, Q is the energy, c is the specific heat capacity of water, and ΔT is the change in temperature. Substituting the given values, we have:
M = 16700J / (334kJ/kg * 1°C)
M ≈ 0.0499 kg
