What happens when thermal energy is applied to an ice cube? (1 point) Responses Its water molecules gain kinetic energy and move around more. Its water molecules gain kinetic energy and move around more. Its water molecules gain potential energy. Its water molecules gain potential energy. Its water molecules lose potential energy. Its water molecules lose potential energy. Its water molecules lose kinetic energy, so the ice cube melts
Its water molecules gain kinetic energy and move around more.
Why does an ice cube melt even in a cold glass of water?(1 point) Responses The ice cube is still colder than the water, so thermal energy moves from the ice cube to the water. The ice cube is still colder than the water, so thermal energy moves from the ice cube to the water. The water is still warmer than the ice cube, so thermal energy moves from the water to the ice cube. The water is still warmer than the ice cube, so thermal energy moves from the water to the ice cube. Ice cubes must always melt eventually. Ice cubes must always melt eventually. 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.
