Look at the data in the table concerning three substances, P, Q, and R.
| Substance | Melting point (∘C^\circ\text{C}∘C) | Boiling point (∘C^\circ\text{C}∘C) | Does it conduct electricity? | Density (g/cm3\text{g/cm}^3g/cm3) |
|---|---|---|---|---|
| P | 114 | 184 | no | 4.9 |
| Q | 1710 | 2230 | no | 2.6 |
| R | 714 | 1412 | Solid does not conduct, but conducts when melted or dissolved in water | 2.3 |
