Which statement correctly compares the thermal energy of ice at 0°C and liquid water at 0°C?
(1 point)
They have the same thermal energy because their temperatures are identical.
They have the same potential energy but have different average kinetic energies.
Ice has more thermal energy because of its organized and solid structure.
Liquid water has more thermal energy because of its higher potential energy.

Liquid water has more thermal energy because of its higher potential energy.
Explanation: at 0°C the molecules in ice and liquid have the same average kinetic energy (same temperature), but melting requires input of latent heat that increases the potential energy (breaks some bonds). Thus liquid water at 0°C contains more internal/thermal energy than ice at 0°C (latent heat of fusion ≈ 334 kJ/kg).
