Q1. Ends of two thin glass tubes are stuck in similar pool of water.  Though both tubes are thin, one tube consists of a smaller inside diameter (Tube 1) than the other (Tube 2). Both tubes are made of the similar material. Would you expect the level in Tube 1 to be higher or lower than that in Tube 2? Illustrate your answer.

Q2. Captain Ahab was sailing in the North Atlantic Ocean when he met up an ice-berg.  Being the savvy nautical mind that he was, he cleverly steered well clear of the iceberg as he and his mates headed south toward more balmy climes. On his way he decided to retrace the route of the British Fleet all through the War of 1812.

(This presumptuous Captain Ahab came after the War of 1812. Apologies to all for any historical or literary inaccuracies).

Captain Ahab finally sailed into the Lake Ontario where, shiver-me-timbers, he encountered an ice-berg of exactly the same overall size, shape and density as the one he encountered before.  Did the ice-berg as well appear exactly the same or was there a difference in what the good Captain saw? Suppose that the density of seawater is more than that of fresh-water.
