Mercury melts at −39∘C and boils at 357∘C. Alcohol melts at −115∘C and boils at 78∘C. At which temperature are both substances in the liquid state?
Melting point of mercury is −39oC and its boiling point is
357oC. Thus mercury remains in liquid form in the temperature range
−39oC to
357oC. On the other hand, m
elting point of alcohol is −115oC and its boiling point is
78oC. Thus alcohol remains in liquid form in the temperature range
−115oC to
78oC.
