222.14 K

256.14 K

273.16 K

245.18 K

- The melting point of ice at sea level and normal atmospheric pressure is widely known.

- At these conditions, pure ice melts at 273.15 K, equal to 0°C or 32°F.

- This value is close to the triple point of water, which is precisely 273.16 K.

- The triple point is when water coexists in three phases: gas, liquid, and solid.

- The correct choice here is option 3: 273.16 K.

- Option 1: 222.14 K is far below any typical water phase transition.

- Option 2: 256.14 K is also below freezing; ice won't melt at this temperature.

- Option 4: 245.18 K is incorrect for similar reasons.
