if ice is melt then it is surely c) option...

But why.

anonymous · Answer

Bcoz if ice will melt then the cool water and air will fall on the thermometer below it...!!!!

abmon98 · Answer

But the question says that ice doesn't melt so how can ice drop water

anonymous · Answer

hmmm... i got the answer....
See!!!!
the c) option is right...
Bcoz when  ice is held in air it releases cool air downwards....
and thus causes decrease in temp. of the thermomete

Is that related to convection a rule in it cool air travels downwards

anonymous · Answer

hmm hmm yeah!!!!!

anonymous · Answer

answer is C guys..cool air is more dense so the bottom thermostat reading will change
