Before we go into the details of whether melting of ice at a room temperature of 25 degree Celsius is spontaneous reaction or not, we first define the spontaneous and non-spontaneous reactions.
Spontaneous Reaction, as you know, is a reaction that takes place on its own without an external force or other reaction to drive it e.g. rusting or iron nail, burning of wood etc.
Non-Spontaneous Reaction is a reaction which cannot occur without the input of work from an external source. Such as charging of battery, as the electrons flow is required to charge it completely.
Now replying to your question: First of all I think, though I am not sure, that heat doesn't transfer from ice to the room. Actually, heat transfers from room to the ice and that's how ice is caused to turn into liquid. The ice needs heat from the surrounding to have its molecules to jiggle (vibrate) and this shaking of ice molecules changes it into liquid. Remember, this reaction is physical, not chemical.
From all I have studied and I know, I truly believe that the conversion of ice into liquid form is spontaneous reaction.

What is the reaction for ice to water?
its called melting.
The melting of ice cubes is an exothermic reaction?
No. The phase change requires adding heat, so melting ice cubes is an endothermic reaction.
Is ice melting in tea a chemical reaction?
a chemical reaction transforms a substance into another. in this case, the melting ice would only add more water to your tea, which is already composed primarily of water, infused with tea (leaves). ice melting is only changes the state of the substance--the substance itself does not change!
Is ice cream melting in a bowl a chemical change?
No. It is purely a physical change, that of melting. No chemical reaction takes place.
What is a spontaneous endothermic reaction?
An endothermic reaction takes in heat from its surroundings. One example of a spontaneous endothermic reaction is an ice pack that doesn't have to be kept in the freezer. When the ice pack is struck with your palm the membrane is broken and the salt is dissolved in the water. The equation would be NH4NO3 plus H2O is equal to NH4 plus NH3.
Is ice melting chemical reaction?
ice melting is a physical reaction
Which reaction is an endothermic reaction?
Melting ice
Is the melting of ice a chemical reaction?
No.

The melting of ice cubes is an exothermic reaction?
No. The phase change requires adding heat, so melting ice cubes is an endothermic reaction.
Is ice melting a physical or chemical reaction?
Physical
The melting of ice cubes is a exothermic reaction?
No, it is a physical change, not a chemical reaction.
How is melting ice a physical reaction?
it is certainly not a chemical reaction, and it is still melting something, so it is a physical reaction. it does depend HOW you melt it, but other than that, it is a physical reaction.
Is a melting ice lolly a chemical reaction?
No ice- cream melting is not a chemical reaction, because with a chemical reaction it is hard to get back the original form. But with ice cream melting that is a physical change because you can easily freeze the ice cream again and get it back to normal un-melted ice cream.
How is melting sugar different from melting an ice cube?
Because melting sugar turns color to form caramel. i.e. it has changed and specifically it has undergone a CHEMICAL CHANGE (Or chemical reaction). When melting ice, no chemical reaction occurs, and so it is just a PHYSICAL CHANGE.
What is the melting of ice?
Scientifically it is an endothermic reaction. Where ice absorbs surrounding heat to form a liquid.
Is cooling a drink by putting an ice cube in it a chemical reaction?
No. The ice melting is a physical change.
