If the melting temperature of hydrogen is -259°C and the melting temperature of oxygen is -218°C then why is the melting temperature of water (H2O) 0°C?

Question

Shouldn’t it be around -245°C?

Answer 1

To extrapolate using your logic: if hydrogen is highly flammable, and oxygen is required for the flame, shouldn’t water be one of the most flammable substances known? 😉
