# Explanation<br /><br />Lithium is a chemical element with the atomic number 3. Its physical properties include a melting point and a boiling point that define the temperature ranges at which it exists in different phases (solid, liquid, and gas). The key points to consider for this question are:<br /><br />1. **Melting Point**: The temperature at which lithium transitions from a solid to a liquid.<br />2. **Boiling Point**: The temperature at which lithium transitions from a liquid to a gas.<br /><br />The melting point of lithium is approximately \(180.5^{\circ} \mathrm{C}\), and its boiling point is around \(1,342^{\circ} \mathrm{C}\). Therefore, lithium exists in the liquid phase between these two temperatures.<br /><br />Given the options, we need to identify the temperature range that falls between the melting point and boiling point of lithium:<br /><br />- **Option A**: from \(-500^{\circ} \mathrm{C}\) to \(0^{\circ} \mathrm{C}\) (below the melting point)<br />- **Option B**: from \(0^{\circ} \mathrm{C}\) to \(100^{\circ} \mathrm{C}\) (below the melting point)<br />- **Option C**: from \(300^{\circ} \mathrm{C}\) to \(1,300^{\circ} \mathrm{C}\) (within the melting and boiling points)<br />- **Option D**: from \(1,500^{\circ} \mathrm{C}\) to \(2,500^{\circ} \mathrm{C}\) (above the boiling point)<br /><br />Based on the melting and boiling points of lithium, the entire sample of lithium would be in the liquid phase in the range provided by **Option C**.<br /><br /># Answer<br /><br />C from \(300^{\circ} \mathrm{C}\) to \(1,300^{\circ} \mathrm{C}\)
