On placing an ice cube inside a glass of water:
We have two glasses of water of same type.In first glass of water we add a ice cube and the ice cube floats in water but in second glass of water we add a ice cube by applying some force on ice cube to keep it under water. Which ice cube melts fast and why?
An ice cube contains a glass ball. The cube is floating on the surface of water contained in a trough. What will happen to the water level, when the cube melts?
