Thermal Equilibrium of an Ice-Water System
A 0.2 kg ice cube, initially at -10°C, is placed into 0.5 kg of water, initially at 20°C, in a thermally insulated container. The specific heat of ice is 2100 J/(kg·K), the specific heat of water is 4186 J/(kg·K), and the latent heat of fusion for water is 334 kJ/kg. Which of the following best describes the system when it reaches thermal equilibrium?
A
All water at a temperature above 0°C
B
All ice at 0°C
C
All water at 0°C
D
Mixture of ice and water at 0°C
