Answer:
Heat will flow from the water into the ice.
Step-by-step explanation:
Heat is a dynamic energy which flow from high temperature object to low temperature object.
So this energy flow due to temperature gradient.
Here when a cube of ice is floating in the water then we know that temperature of ice cube is less than the temperature of water always.
So here when we mix them then heat will flow from water to ice cube as it always flow from high temperature to low temperature
So here the correct answer will be
Heat will flow from the water into the ice.
