Why does an ice cube melt even in a cold glass of water?

Question

• The water is still warmer than the ice cube, so thermal energy moves from the water to the ice cube.
• The air around the water melts the ice cube.
• The ice cube is still colder than the water, so thermal energy moves from the ice cube to the water.
• Ice cubes must always melt eventually.

Answer 1

The correct answer is: The water is still warmer than the ice cube, so thermal energy moves from the water to the ice cube.
