First it floats, then it melts and makes the water colder.

A glass of ice water is an object.
they are both water
The temperature will be the same.
Ice is less dense than water and therefore floats on water so when the glass has water in it the ice will always stay above the water.
If he glass was full and you put ice cubes in it would overflow strait away.
increases
Stays the same (assuming that all the ice was floating to begin with).
When the ice melts the water level will rise. The water level will increase because Ice is frozen water and when the ice melts, it turns to water, which means more water will be added to the glass.
If both of them consist of water and ice at the same time then the temperature for both of them is zero Celsius (from the heating curve of water)
An ice cube will dissolve in water because the water is warmer than the ice.
Because the water is probably warm enough to melt the ice in the water.
