Why does ice change to water as energy is added at the melting point? a. Kinetic energy is removed from the molecules, so they separate.
b. Molecular motion decreases until the temperature begins to increase.
C. Molecules vibrate quicker, and their motion overcomes the forces of attraction.
d. All the forces of attraction between molecules disappear at the melting point.

C.

Explanation:

Melting happens when the molecules of a solid gain enough momentum that the motion overcomes the attractions, allowing the molecules to move. Molecular motion does not decrease; this occurs when liquid freezes. Neither will it 'disappear'.

This motion comes from kinetic energy is being added to the molecules, not removed. This 'excites' the particles, which breaks the bonds that hold them together, which results in solid melting into water.

Therefore A, B, and D are incorrect, making C correct.

C. Molecules vibrate quicker, and their motion overcomes the forces of attaraction.

Explanation:

Temperature remains constant as the ice gradually changes to liquid state; melting point. It remains constant as the increased kinetic energy it had acquired makes its molecules vibrate vigorously causing further weakening between the molecules. Therefore, the ice changes to water as energy is added at the melting point.

im guessing the west of station b

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
