What is the melting point of Ethanol?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 156 K
Ethanol freezes at about −114°C, which on the Kelvin scale is roughly 156–159 K — the value of 156 K given here. Its boiling point, by contrast, is 351 K (78°C).
The very low melting point is why ethanol stays liquid in thermometers and antifreeze mixtures far below the freezing point of water, which is 273 K.
