1 oz of water
The water raises the temperature of the ice cube
This depends on the type of water used to make ice.
An ice cube will dissolve in water because the water is warmer than the ice.
The ice melts and the water gets cooler.
An ice cube is just frozen water. When an ice cube melts it becomes water. Eventually, the water will evaporate.
A sea water ice cube -- Because the melting point of sea water is lower than that of normal water.
ice cube
Salt water will melt an ice cube faster.
it depends on the size of the ice cube
An ice cube melts faster in salt water.
Heat will flow from the boiling water into the ice cube.
That would depend on the temperature of the cube and the water along with the volume of water and the mass of the ice cube and its area.
