It depends slightly on the atmospheric pressure. At standard pressure the answer is 0 C or 32 F
Before melting the temperature of the ice is under 0 0C.
The ice is at a constant temperature of 0°C as it melts. Once it has completely melted, the water's temperature will start to rise to equilibrium with the room.
Room temperature
No, it stays at the freezing temperature of water until it has all melted.
Its ok as long as you let the water cool to room temperature before adding the water back to the bowl, or adding the betta to the water. Also, it is completely unnesseary to boil before putting in your betta's bowl.
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.
The same temp as the room it was placed in
The ice is at a constant temperature of 0°C as it melts. Once it has completely melted, the water's temperature will start to rise to equilibrium with the room.
Room temperature
The hot water will get colder and the ice will melt and the water from the melted ice will get to the same temperature as the final temperature of the hot water.
No, it stays at the freezing temperature of water until it has all melted.

A thermometer placed in iced water can be expected to indicate a temperature of around 0oC, as this is the temperature at which water freezes. The temperature indicated may be higher if there is a lot of water relative to ice in the container (for example, if a lot of ice has melted).
Well, yes, but the water must be very hot. Not just like the water temperature that we shower in.
The heat going into the ice initially breaks the hydrogen bonds between water molecules, during which the temperature remains constant. Once the hydrogen bonds are broken, the heat will go into melting the ice and the temperature will increase.
yes
No, because melted ice is water - you drink water.
Melted ice is liquid water and water boil.
