What is the melting point of ethanol?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 156 K
Ethanol (\(\ce{C2H5OH}\)), the alcohol found in drinks and used as a fuel and a solvent, is a liquid at room temperature. Its melting point is commonly given as 156 K (about −117°C) and its boiling point as 351 K (78°C); precise measurements put the melting point a little higher, at about 159 K (−114°C). Since this lies far below room temperature (about 298 K), ethanol stays liquid in everyday use.
