The melting points of two liquids, Liquid X and Liquid Y, are shown in the table:
| Liquid | Melting point (∘C^\circ\text{C}∘C) |
|---|---|
| Liquid X | -130 |
| Liquid Y | -95 |
Which of these two liquids is/are suitable to use in a liquid-in-glass thermometer to measure temperatures of −80∘C-80^\circ\text{C}−80∘C and −120∘C-120^\circ\text{C}−120∘C?
Liquid X only
Liquid Y only
both Liquid X and Liquid Y
neither Liquid X nor Liquid Y
