Which Inorganic Substance has a melting point of -101°C and a boiling point of -35°C?
Group of answer choices

A. Chlorine

B. Hydrogen

C. Hydrogen Sulfide

D. Hydrogen Chloride

Respuesta :

The inorganic substance that has a melting point of -101°C and a boiling point of -35°C is chlorine (option A).

What is melting and boiling point?

Melting point is the temperature at which the solid and liquid phases of a substance are in equilibrium.

On the other hand, the boiling point is the temperature at which a liquid boils, with the vapor pressure equal to the given external pressure.

Chemical elements and compounds have specific boiling and melting points that distinguishes them chemically.

The following are the melting and boiling point of the given compound and elements respectively;

  • Chlorine - -101°C and -35°C
  • Hydrogen: -259.2°C and -252.9 °C
  • Hydrogen sulfide: -85.5 °C and -60°C
  • Hydrogen chloride: -114.2 °C and - 85°C

Therefore, the inorganic substance that has a melting point of -101°C and a boiling point of -35°C is chlorine.
