If Ice cubes are melting in water, the temperature of both the ice cubes and the water will be exactly the freezing temperature of water: 32F, 0C. You cannot change this. You can add heat to make the ice cubes melt faster, but the extra heat will have no effect on the temperature, It will all go to melting the ice cubes.
this will depend on the temperature of the atmosphere the ice cube is in and the surface area to volume ratio of the ice cube amongst other things....
the temperature of ice cubes are lower than the temperature of the water around them. The heat energy from the water is used up in the process of melting the ice, so the water temperature drops.
Its a physical change because it can be reversed by re-freezing the water.
No, freezing is exothermic as the water loses energy to its surroundings as it freezes.
Ice cubes explode in a drink because they are melting at a fast rate. The ice cannot contract fast enough to keep up with the melting, which causes it to crack.

Ice cubes that are in water are in full contact with a liquid medium with high rate of heat transfer. in soda, some of the surface of the ice is in contact with gas bubbles that have low rate of heat transfer. Liquid transfers heat (melting the ice) faster than air.

No. The phase change requires adding heat, so melting ice cubes is an endothermic reaction.
this will depend on the temperature of the atmosphere the ice cube is in and the surface area to volume ratio of the ice cube amongst other things....
the hotter the water the faster the ice will melt
Melting is easier.

It is PHYSICAL because when the ice cubes melt, they turn into water. We can reverse the change and bring the water back into ice. Water has a chemical formula of H2O and so does ice. So, Physical Change: can be reversable, the object's components don't really change.
