The melting point of gallium is about 30°C, while the freezing point of water is 0°C. To find out how much warmer the melting point of gallium is than the freezing point of water, we can subtract the freezing point of water from the melting point of gallium:
Melting point of gallium - Freezing point of water = 30°C - 0°C = 30°C
Therefore, the melting point of gallium is 30°C warmer than the freezing point of water.
