Melting point & boiling points of liquid oxygen are respectively – 218.8°C & – 183°C, while the same for liquid nitrogen is – 210°C & – 195.8°C respectively. The difference in melting points of liquid oxygen & liquid nitrogen is not equal to 8.8 ?
Correct answer: A
Explanation
The question asks for the unit of the difference in melting points. Since the given temperatures are in °C, the difference must also be in °C.
