It is a well known fact that melting of an ice cube floating on pure water does not change the water level. Then what will happen if an ice cube floats on a liquid that is not pure water? Consider the following situation:
Johnny ordered a whiskey-on-the-rock. A large ice ball is freely floating on his whiskey. Determine what happens to the surface level of his whiskey when the ice ball melts completely.
Details and Assumptions
- There is enough whiskey for the ice to float freely (unlike the image).
- The density of pure water (as a liquid) is 1.00 g/ml.
- The density of the ice ball is 0.90 g/ml.
- The density of Johnny's whiskey is 0.95 g/ml.
- Johnny does not drink his whiskey before the ice ball completely melts.
- Ignore any evaporation.
P.S. There is more beyond the calculation, but the answer is indisputable!
