Answer:
Gallium is solid at 300K
Explanation:
X °C = 300 kelvin - 273.15 = 26.85 ° C
To know if Gallium is solid, liquid or gas; we should know the melting point of Gallium.
The melting point of gallium is 29.76 °C, which is 3 °C higher than the current temperature. This means it hasn't melted yet. So at 300 Kelvin, it is still solid. But the melting temperature is slightly above room temperature.
