- The freezing point of water / melting point of water is 32f / 0c / 273k
- 0 c is lower than 1538 c
- The melting point of iron is 2800f / 1538c / 1811k
- Hence, the melting point of water is lower than the melting point of iron

- -2188 c is lower than 0 c
- The freezing point of water / melting point of water is 32f / 0c / 273k
- The melting point of oxygen is -3618f / -2188c / 544k
- So, the melting point of oxygen is lower than the melting point of water

- The melting point of water is lower than the melting point of iron
- The melting point of oxygen is lower than the melting point of water
- Therefore, the melting point of oxygen is lower than water and the melting point of water is lower than iron

Hence, the melting point of oxygen is lower than water and the melting point of water is lower than iron
