MCQ? Where are the choices?Originally posted by bonkysleuth:Some scientists predicted that there are rivers of methane on a moon called Titan. Methane has a melting point of -182 degrees celsius and a boiling point of -161 degrees celsius. What do you think the temperature on the surface of Titan is that led to the scientists' prediction?

Anyway, I will pick any answer between -182 and -161.
There was some technical glitches with my computer just now. Sorry for the delay. But I've since edited the post.Originally posted by SexyChin:MCQ? Where are the choices?

A.above -161 degrees celsius(BP), methane(CH4) will be at its gaseous state.Originally posted by bonkysleuth:Some scientists predicted that there are rivers of methane on a moon called Titan.

A. above -161 degrees celsius
B. below- 182 degrees celsius
C. between -182 and -161 degrees celsius
D. it's impossible to tell
And why is that so? Cuz the question's asking us about the temperature on the surface of Titan and not Methane. I'm kinda confused with the phrasing of the question.Originally posted by iwantbeautifulteeth:A.above -161 degrees celsius(BP), methane(CH4) will be at its gaseous state.
B.below -182 degrees celsius(MP), CH4 will be at solid state.
C.b/w -182 and -161 degrees celsius, CH4 will be in liquid form.
ans is C.
