Last night I was enjoying a drink with my dinner. I noticed that after about 5 minutes of not touching the drink that some of the ice had melted but the liquid level in the cup had actually went down. This was similar to the below situation that Dr. Placek presented in class about the anchor and the boat. Because liquid water is more dense than frozen water the liquid in the cup occupied less volume and became increasingly dense as the ice melted.
You're in a boat and you have an anchor that weighs 50 lbs. You decide to throw the anchor overboard. The anchor is made of a material that causes it to sink to the bottom and is not attached to the boat by a rope. Does the water level in the lake A.) stay the same? B.) go up? C.) go down?
correct answer: C The anchor displaces more water while in the boat than in the lake. This is due to Archimedes principle
