Mike and Vince were in the music room at their school. Vince placed a glass of water on top of the piano. He noticed that as Mike played the piano, the glass vibrated and the water inside moved. Vince wondered how the water could be moving without him touching the glass. Mike explained that since sound waves move through matter. Complete the sentence: So, when he played the piano, the __________ energy of the matter increased. This increase leads to the movement of the water and glass. As Mike played _______________________________.

Kinetic, more loudly the glass' vibrations increased
c)
Thermal, more quietly the glass' vibrations increased
d)
Potential, more quietly the glass' vibrations increased
