The diagram shows a flask which has been filled with liquid X at room temperature.
When the flask is placed in warm water, the liquid rises higher up the tube. When the flask is put in cold water, the liquid drops below the original level in the tube.
The experiment is repeated using an identical flask but a different liquid Y. The initial level of the liquid in the tube is the same as that in the original experiment.
Liquid Y expands more, per degree increase in temperature, than liquid X.
Which row is correct for the level of the liquid?
1 )
rises most in warm water:X / falls most in cold water:X
2 )
rises most in warm water:X / falls most in cold water:Y
3 )
rises most in warm water:Y / falls most in cold water:X
rises most in warm water:Y / falls most in cold water:Y
