Some scientists predicted that there are rivers of methane on the moon called Titan. Methane has a melting point of -182 deg. C & boiling point of
-161 deg. C. What do u think the temperature on the surface of Titan is that led to the scientists' prediction? A) Above -161 deg. C, B) Below -182 deg. C, C) Between -182 & -161 deg. C, or D) It is impossible to tell.

If methane exist on the surface of moon called Titan in liquid state, then the surface temperature of Titan has to be less than boiling point of methane and more than melting point of methane. Thus means surface temperature of Titan must be between -161 degrees C and - 182 degrees C.
Therefore among the options given, option C0 is the correct answer.
