Juan observed the ice as it melts on the table. He wondered what happened to the movement of the particles present on the ice. Which of the following concepts can help Juan?

• A. The movement of the particles become slower as phase change happens.

• B. The movement of the particles become slower because there are spaces between particles.

• C. The movement of the particles become faster because the particles in ice is faster than the particles in water.

• D. The movement of the particles become faster because the temperature of the ice changes sufficiently as phase change happens.

• D. KE is constant

Why is it that ice is less dense than water?

• A. The negative-charged oxygen atoms repel each other.

• B. The ice melt easily and the bond between the molecules break.

• C. Less amount of temperature for the water molecules brought to be closer.

• D. The hydrogen atom in a molecule attracts the oxygen atom in another molecule.
